Chapter 1 DESIGNERS GUIDE

The structured cabling systems used by DET NSW follow the guidelines of the Australian Standards. However the standard’s SCS structure does not fully satisfy the educational requirements. Hence there are enhancements to the standard’s commercial structure to meet the educational requirements. DET use three SCS structures, Office, TAFE Campus and School. Albeit these structures are separate there are facets of each which may apply to the other depending on the nature and requirements of the site.

DET SCS Structures Office SCS Structure

The office structure is basically the same as the commercial structure. The main differences being the use of three TOs in the work area and the use of a free standing combined Telecommunications and Server Cabinet (in smaller offices) for the TC. The three TOs are mandatory for workstations and offices. The number of TOs in other work areas such as meeting rooms, utility rooms and printer rooms will be determined by the customer’s requirements and shown in the functional specification. However the TOs are to be grouped in a triple TO enclosure. The use of a combination telecommunications/server cabinet will be determined by the customer. And maybe supplied by the customer. This will be stated in the functional specification for the SCS.

Combined Telecommunications and Server Cabinet The function of the combined Telecommunications/Server Cabinet is to house the SCS, LAN equipment and servers plus a UPS. It is envisaged that the cabinet and contents will be recycled in another DET office upon removal. The removal of the cabinet will be as simple as cutting incoming cables, securing of servers then roll it out the door. The cabinet is to be located in an area that will allow for the noise of the Servers and LAN equipment. Preferred locations are Utility rooms, staff common areas or stores. The cabinet relies on the fan forced ventilation of the equipment and the available office air-conditioning. Therefore the cabinet is not to be located in an enclosed area where there are less than seven air changes per hour. Office fit-outs of 750 square metres or less are suitable for a single cabinet. Larger offices will require 2 cabinets



Page–11

A Cabinet Specifications are detailed in Rack Specification within the Technical Specification section.

TAFE Campus SCS Structure The TAFE campus structure varies from the commercial structure in its concentration of telecommunications outlets in learning areas. The learning areas are serviced with horizontal cabling. Therefore classrooms will typically contain sixteen to twenty telecommunications outlets The functions of classrooms in campuses are subject to change. Thus it is possible for a classroom with no telecommunications outlets to be changed to a fully populated computer room. Thus to allow for the changes pathways and cabinets must be sized adequately. Refer to the Distributor Rack Size chart. In all cases the absolute minimum size must allow for 100% expansion of both the FD and LAN equipment plus cable management. The type of LAN equipment used and operational requirements in campuses will vary. Thus the layout of the SCS within the cabinets is subject to the campus requirements. Designers are to consult with the relevant regional TAFE Information Technology personnel to ensure the layout of the SCS is as required by the campus.

School SCS Structure The School SCS structure is restricted to a three tiered distributor model. The objectives of this design are to:

• allow the LAN to operate to a maximum of a three tiered hierarchical format only

• minimise the requirement for active equipment • simplify operational requirements

In some schools it maybe possible to install a single CD to service all work and learning areas. In this instance all pathways will be of a lay-in nature and allow for 100% growth. The rack space must also allow for 100% growth for both the horizontal cabling and the LAN equipment. The schools building distributors by definition under the AS/NZS3080 standard are technically a two connector floor distributor. However in the Schools environment these distributors are known as building distributors (BD’s). The Classroom/Local Distributor is restricted to a single learning space such as the classroom. In some instances where there are a small number of devices in close proximity the distributor will be the interface of the LAN equipment. Thus device leads can be used. Alternatively a room can be cabled with fixed cabling consisting of telecommunication outlets and a distributor panel and cabinet.


SCS Services Network Services

The SCS has been designed to meet the requirements of the applications and hardware recommended by ITD. The campus and building backbone is to be capable of supporting the Gigabit Ethernet (1000BaseT, 1000BaseSX & 1000BaseLX) protocol. Provision has been made for the support of IEEE 802.3ae (10GBE) and 100 GBE. The protocol used to the desktop is typically Fast Ethernet (100BaseTX) and can be Gigabit Ethernet.

Telephone Services The typical telephone services will be distributed by the multipair Class B UTP backbone cabling. New Voice over Internet Protocol (VoIP) services is being implemented. These services will be distributed as a Network service. The typical 100mbps (100BaseTX) is satisfactory for this application.

Audio, Video and Image Services The audio, video and image services now comprise both digital and analogue distribution requirements.

Digital Distribution The digital (audio, video and images) services will be distributed same cabling infrastructure as the Network Services and will considered as a component of Networks Services from here on in.


Page - 12 -



Page–13

A separate specification for digital services distribution is being developed. The specification will be application oriented and no additional cabling will be required in the SCS.

Analogue Distribution The analogue video (Real time - Free to Air - TV) will be distributed by a MATV and separate RF cabling system. The determination to install the RF cabling plant will be determined by the designers of the functional specification.

SCS Administration The administration of the SCS is important to the effective use of the SCS. The labelling of the system, the identification of its components and the recording of the "work-as-executed" must be comprehensive and clear. Without this, the user will have unnecessary difficulty in troubleshooting or the implementing changes. If a certified SCS is installed then additional administration is required to ensure the integrity of the system. The administrator will need to ensure that only qualified cabling contractors are used to perform adds, moves and changes.

Cable Jointing Optical Fibre Cabling

The preferred method of fixing broken optical fibre cables is to replace the entire length of the cable. However, due to expediency the cables (both external and internal) maybe repaired by the fusion splicing method. The decision to replace the cable or to repair it is the sole right of the DET entity and its management. If there is insufficient cable length to join the cables the entire cable will be replaced. Short lengths of cable are not to be inserted. The repaired section must be accessible for maintenance and inspection.

Multipair CBC New installations of multipair backbone cables are to be continuous from CD to BD. Jointing and/or dividing cables are not permitted. Repairs may use the appropriate jointing assemblies. Additional multipair CBC will normally run from the CD. Where there are sufficient pairs in the CBC to provide a 100 percent expansion over the designed use the multipair CBC may be run from a BD.

Telecommunications Closet (Building Distributors) Location of Telecommunications Closet (TC)

The TC is to be located in either non-student or supervised areas only. Under no circumstances is a TC to be located in a corridor or be accessible from the exterior of the building. E.g. landings and verandas. The TC may form part of the general office environment. The area for the TC must be designated and used solely for the function of the TC. All equipment used in a general office TC must be housed in a secure cabinet.



Page - 14 -

Cooling and ventilation The TC will have as a minimum fan forced ventilation. If the TC is enclosed in a small room the room must have a minimum of seven (7) air-changes per hour. In areas where the temperature regularly exceeds 28 degrees Celsius air-conditioning is to be fitted.

Equipment Mounting All passive and active equipment is preferred to be mounted into Equipment racks.

Wall Surfaces - Condition & Mounting All masonry walls of the TC will be painted. All surfaces intended for mounting of active and/or passive equipment will be fitted with a melamine backing board. The board will be 16 mm thick. A minimum of 10 mm clearance from a masonry wall surface is required.

Power Requirements Each telecommunications closet must have within it or in close proximity at least one 10A double socket outlet for the technician’s use. Wall mounted enclosures/racks require a 10A double socket outlet on a dedicated circuit for the internal power rail connection. In larger installations where a floor mounted racks are provided a 15A industrial socket outlet with a screw locking ring must be provided. The circuit to the TC must be earth leakage and surge protected.

Adding Cabling to existing Cable Plants Existing Distrutors

When adding horizontal cabling to existing distributors the following guidelines apply. • If there are existing Class D panels with spare connectors then these are to be

used. Certification must still be supplied for these outlets. • If the cabling works exceeds the number of spare Class D connections then new

Class E panels and cabling will be installed. • All new distributors will be Class E cabling.

Existing AVMRS systems

If the site has an existing AVMRS the new telephone backbone cabling must be terminated using four pair termination method. The first four pairs of the multipair cable will be terminated onto the first 8 position modular outlet of the Voice Patch Panel. The subsequent groups of four pairs will be terminated on to the next consecutive 8 position modular connectors of the Voice Patch Panel. The pairs will be terminated as per pin pair assignment T568A. A minimum of 25 pairs will be run in Primary schools and 50 pairs in Secondary schools. The panels will include labelling that states “Voice & Video use”



Page–15

Existing IDC (110) Frame Installations

TAFE NSW had previously standardised on an IDC 110 frame for the SCS. If the functional specification for a TAFE NSW site stipulate the IDC 110 frame to be used then the termination method will as per EIA/TIA 568A - Method T568B.

Remote Buildings Connected to a Distributor A remote building is considered to be a freestanding building with no interconnecting structure or at best a temporary covered walkway. E.g. Demountables, sheds and stores. It is considered that remote buildings will be at the edge of the cabling infrastructure and that no other distributors will be connected to them. Remote buildings that have cable runs less than ninety (90) meters from a BD/FD and fewer than 16 cables may install external UTP cabling. However the below comparison of UTP over optical fibre must be applied. If UTP is installed lighting protection must be fitted.

External UTP or CBC comparison The use of external UTP over CBC will be determined on a practical cost basis. As the number of external grade cables run to the remote building increases the cost also increases. Thus the maximum practical distance between the remote building and BD decreases. A recent evaluation for the connection of the Modular Designed Resource buildings revealed that for 16 external UTP cables the practical distance between the BD and the remote building was 40m. Hence quotations for each cabling method will need to be acquired to determine suitability. A reduced size in CBC can be implemented. Typically a six (6) core multimode optical fibre cable for Network Services and two (2) four (4) pair external grade Cat 5e UTP cables for Telephone Services. The calibre of the CBC must equal that of the CBC equipment specification.

Considerations when cabling of Demountables Temporary Buildings

Demountables by their nature are “temporary”. Thus covered walkways to these building are also classified as temporary. Therefore the running of CBC within these covered walkways is not recommended. However the cost comparisons of UTP verses optical fibre must be applied.

Apparent ad-hoc removal of Demountables Demountables are added and removed by function not position. Thus it is possible that a demountable that is cabled as a distributor to other demountables will be removed first. Therefore consultation with DET is required to choose the most appropriate demountable for a distributor.



Page - 16 -

Fully enclosed cable pathways in the Sub-Floor Space The cable pathway under Demountables that have the sub-floor space unsecured must be fully enclosed. Typically PVC conduit is to be used.

VoIP’s affect on the CBC Typically if a new CBC was installed it would comprise a 6 core MM and 6 core SM fibre cable plus a 30 pair UTP multipair cable. As VoIP is a network service there is no need to run the 30 pair UTP cable if there is an existing voice block cabling system. When new buildings are being installed and no other UTP backbone cabling exists then the 30 pair UTP CBC is to be installed.

Wireless LANs The infrastructure and configuration rules for wireless LAN are not covered in the SCS specification. For those wishing to implement wireless LANs the “Wireless_Installation_Primer.doc” has been created and may be found on the DET ITD telecommunications web page.

Distributor Rack Sizes The size of the racks to be installed will be determined by the size of the floor space being serviced by the distributor, not by the quantity of cables being installed. The table below states the size of the racks in “Rack Units” (RU) for a given floor area and the type of DET SCS. The sizes have been determined through practical application and averaging. Therefore the designer must consider the requirements of the SCS being designed as the rack may need to be larger.

Lightning Protection Telephone Services

Lightning protection for telephone services in the CD & BD will be determined by the AS 4262.1, & S009. The requirement for the lightning protection will be determined in functional specification. However it must be recognised that the Lightning Protection devices are not necessarily suitable for digital, analogue or other “Power over Ethernet” technologies such as VoIP telephone services.

Network Services Lightning protection is required to protect the communications equipment when the connecting UTP cables are run external to the building housing the distributor. This includes both underground UTP & internal grade UTP in covered walkways. The lightning protection device/panel is to be fitted according to the manufacturer’s instructions and mounted in the Building Distributor. (It must be earthed) The LPD must protect all conductors and have an application performance not less than AS3080:2003 Class D or 100BaseTX. One LPD circuit must be allocated for each 4 pr UTP cable run externally. All 8 wires must be protected. The products that have been tested to operate with 100BaseTX are in the table below. Should other products be used it is the responsibility of the contracted entity to warrant the performance of the protection device. An additional patch lead will be provided to connect between the LPD and active equipment port. The length of the cable will be dependant on the layout of the Distributor and the performance of the cable will be no less than the ITD – IS315xx lead.

Cable Management on Panels Horizontal and vertical cabling management will be installed in the CD, BD & FD. The front rails of the equipment racks must be set back at least 100 mm from the front of the inside of the front door.

Horizontal Cable Management A 1 RU cable manager will be used for every 2 RU of Distributor panel. The Panduit Network Cable Manager is preferred as the UTP Class E bend radius is maintained and a cover is supplied. Alternative managers may be supplied but must meet the same bend radius and be fitted with a lid.

Vertical Cable Management Vertical cable management rings/loops are to be fitted to both sides of the racks at one per four RU. A slotted duct system with bend radius management is also acceptable.

Cross-Connect leads (Customer Patching) Cross-connect leads may be supplied to allow the customer to perform the patching associated with adds, moves and changes. The leads are to match the performance criteria of the application being patched. Patch leads for voice connections are to use flat ribbon cable. This provides easy identification of voice connections. Patch leads for all other applications are to be a minimum of Category 5.

Campus backbone cabling subsystem Inter- building cable types

Network Services Optical fibre cable is the preferred medium. Optical fibre cable allows for high bandwidth applications on the Campus Backbone Cabling (CBC). The Gigabit Ethernet (GBE) protocol is the DET campus network protocol. The use of single mode optical fibre cables in the CBC allows for the future applications of 10GbE & 100GbE in the CBC. The optical fibre cables used from the CD to BD will be of composite construction – 6 cores of multimode and 6 cores of single mode. However where issues of certification and supply exist two separate cables are allowable. Optical fibre cables that are installed underground or in covered walkways with exposed cable pathways must be loose tube jell-filled. Optical fibre cables that are installed on masonry building structures that are not in direct sunlight or subject to moisture can be tight buffered internal grade. Cables with a polyethylene sheath (indoor/outdoor) are preferred. However the minimum pathway and products specified in S008 & S009 applies. The availability of additional/redundant fibre cores allows the use of other non network applications. E.g. CCTV. However there must be a minimum of 100% redundancy for Network services. Thus if the network service uses 2 cores of the multimode optical fibre cable then only 2 core may be used for other services. Class E UTP may be installed where the cable run to the BD is less than ninety (90) meters from the CD. The pathway between the CD & BD must be classed as internal (no use of lightning protection). The use of Class E UTP between distributors is intended for larger buildings, concrete linked walkways and office buildings.

Telephone Services Class B UTP cable is the minimum standard required.

Inter- building pathway Inter-building pathways must provide security and expansion. Underground pathways and metal enclosed pathways are mandatory for exposed environments. Underground pathways are preferred. All pathways are to be installed with an allowance for 100% increase in capacity. All pathways must be accessible.



Page–23

Underground conduit and pit system

The size of the underground conduits will be a minimum of 100 mm. Markers identifying the direction of the conduit with the “Communications Cabling” are to be placed on a permanent and visible location. Pit wills be placed at the entry and exist points to buildings. Services will run from this pit to the building sized to suit this service. If the pathway for this service can be shared then a minimum size of 50mm conduit is required.

Covered Walkways Covered walkways have been used to support the pathway for the campus backbone cabling. The use of some walkways has proved troublesome and costly. Due to inconsistencies and timing of construction of the walkways. Thus covered walkways have not always been practical for the pathways. The appropriateness of the walkway must be determined prior to designing the pathways. If there is doubt to the appropriateness then the pathway is to be an underground conduit and pit system. Some of the factors that determine the appropriateness of the walkway are:

• the construction material of the walkway • the alignment of the sections – if there are steps in the roof alignment • the security and height of the pathway attached to it • the connectivity method of the walkway to the adjoining buildings • the intended life of the walkway relative to the 20 year Certification

Covered walkways that protect the cables (including supporting conduits or trays) from the direct sunlight and moisture and the roof structure is electrically bonded the full length of the walkway and to roof structure of the egress and ingress buildings will be considered as internal pathways. However should any portion of the cable pathway be exposed then the entire walkway will be deemed as external. Thus cables run on top of the walkway or in open spaces due to steps in the roof alignment must be external grade and lightning protection will be required.

Aerial Catenaries All fittings including catenary wires (where external to the cable) will be made of Grade 316 stainless steel. The cable will be secured to the catenary wire with wire wrap or stainless steel cable ties. PVC cable ties (white or black) are not to be used. Mounting brackets are to be fastened to masonry walls or structural timbers. Barge boards or facial boards are not to be used Copper cables are not to be installed aerially.



Page - 24 -

Cable Trays & Ducts Wherever possible the inter-building pathway will be run using existing building structures. This is to be a shared pathway with other services. The allowed services are determined by ACA standard S009.

Cable Termination Methods Voice Multipair Cable

Office and TAFE Campuses The voice multipair cables will be terminated on 8 position modular panels. Each pair of the multipair cable will consecutively terminated onto pair one (blue pair) of the 8 position modular connectors within the Voice Patch Panel. School Campuses Two pair termination will be used. Pairs one and two as per termination method T568A will be used on consecutive 8 position modular outlets of the Voice Patch Panel. Thus primary schools will have 12 connections in the CBC and secondary school will have 24 connections. Refer “Design Guide” for schools with an AVMRS.

Optical fibre Cable External and/or Single Mode The termination method of external grade and single mode optical fibre cable will be fusion splicing. Internal Multimode The termination method of internal grade multimode optical fibre cable may be direct termination. However where composite cables are used the multimode optical fibre cores are to be fusion spliced. Enclosures and Panels Optical fibre enclosures and panels are to suit the cabinet used for the distributor. Enclosures are to be fully encased with entry glands and/or supports for the cables. The panels are to present the SC connectors at an angle which assists in the reduction of bending the optical fibre leads. A protective cover or cable management is to be fitted to the front of the panel for the protection of the optical fibre leads.



Page–25

Optical fibre Colour Codes Single Mode Cables & Connectors

All leads and internal grade cable will be “YELLOW”. All connectors (on leads and patch panels) will be “BLUE”.

Multimode Cables & Connectors All leads and internal grade cable will be “ORANGE”. All connectors (on leads and patch panels) will be “BEIGE”.

Optical fibre patch panel layout The optical fibre patch panels will be installed with the multimode first and single mode second. The six (6) cores of multimode optical fibre will be installed in the first six positions of the patch panel. This will typically be cores 1 to 6. The six (6) cores of singlemode will be installed in the next consecutive positions after the multimode optical fibre. Typically this will be cores 7 to 12.

Telephone Services Cabling VoIP Systems

The DET VoIP system may or may not use PSTN services as connection to the public world. Those systems that do will require a 10 pair voice grade cable run between the MDF and a modular distribution panel in the CD. Those that don’t will use the SCS to connect to the appropriate devices. The connection of IP handsets will use the SCS.

PABX Systems The telephone service cabling comprises the cabling plant to connect the incoming carrier lines, the PABX and its extensions plus distribution throughout the campus. MDF/Test point frame On sites that have an existing MDF the new frame will be a Test Point Frame. On sites that are new the frame will be the MDF. The frame is to be operationally the same as the Krone LSA-PLUS product. The frame size will be a minimum of 250 pair terminations. The frame will be used for:

• the exchange lines to the PABX • the extensions from the PABX • the Carriers lead-in cable • distribution to existing block cabling


• distribution to SCS The telephone extensions will be terminated onto the Active Voice Patch Panel using one pair termination. Each consecutive pair will be terminated onto an 8 position connector onto pair one (1). Mounting of PABX The PABX will be mounted within the CD rack. Eight rack units have been allocated for the mounting of the PABX. The mounting maybe onto separate rack mountable structures or use the rack rails.

Labeling All components of the SCS will be labelled. Particular attention is to be paid to the labelling of the Voice panels, MDF/PABX incoming lines and Campus Backbone Cabling areas. Campus Distributor cables and termination panels will be labelled with origin and destination details. Plus pair and/or core numbers. All labelling will be machine printed. Hand written labels on panels is not acceptable.

Campus Distributor Layout The layout of the various components of the campus distributor is to be as per the drawing below. The layout is shown for one and two rack campus distributors.


Page - 26 -


Inter-rack Pathway The SFS Design Guide requires up to three racks to be installed. The LHS rack is designated the CD Rack, the middle rack is the AV rack (in Primary Schools) or an extra distributor rack (if required - in Secondary schools) and a Server Rack. These racks will be placed adjacent to each other. The sides of the rack MUST remain fitted. To enable communication cables to be passed between the racks a Cable Pathway is to be provided. This pathway must be accessible to operators. The below drawing suggests a duct system that passes over the top of the racks with access to the racks at the rear LHS of the racks. The access hole must control the minimum bend radius of the proposed cables. Additional vertical cable management is to be fitted to enable orderly distribution of the cables throughout the full height of the rack. The duct maybe of any suitable material, PVC, metal or wire basket etc. However it is to be durable and rigid. The below drawing is not to scale and site conditions may require an alternative pathway.

Building backbone cabling subsystem Intra-building cable type

Network Services Multimode optical fibre cable will be installed between the BD & FD. Single mode is not required. Class E UTP may be installed where the cable run to the FD is less than ninety (90) meters from the BD.

Telephone Services Class B UTP cable is the minimum standard required.

Intra-building cable pathway All pathways are to be installed with an allowance for 100% increase in capacity. All pathways must be accessible.

Cable Trays & Ducts Wherever possible the intra-building pathway will be run using existing building structures. This is to be a shared pathway with other services. The allowed services are determined by ACA standard S009. The pathway must allow for the installation of an optical fibre cable. PVC duct maybe used in exposed supervised areas within the building (classrooms, offices etc). Metal duct is to be used in exposed unsupervised areas within the building (corridors, common areas etc).

Cable Termination Methods Voice Multipair Cable

Office and TAFE Campuses The voice multipair cables will be terminated on 8 position modular panels. Each pair of the multipair cable will consecutively terminated onto pair one (blue pair) of the 8 position modular connectors within the Voice Patch Panel.

Horizontal cabling subsystem Cable type

Class E (Category6) cable will be used for all new distributors and existing distributors that require additional patch panel assemblies. See “Design Guide” for other scenarios.

Distributor Patch Panel The distributor patch panel will be a generic application panel. i.e. any outlet maybe used for any application (network or telephone etc). The patch panel will form one patch field. All outlets will be installed sequentially. A one meter service loop will be installed a close as practical to the patch panel. It is not to be installed in the panel area or obstruct pathways. It must be secured, accessible and easily upgradeable.

Telecommunication Outlets The pin and pair assignments will be as per AS/NZS 3080(Int) Figure ZA.2 (a) T568A. (Warning:- TAFE NSW sites are typically T568B) TOs may be installed in any quantity as required by the area being serviced. The TOs are to be installed in face plates, surface mounting boxes and Multi-User Telecommunication Outlet enclosures to suit the number of required TOs. It is preferred that the TO are to be mounted in the horizontal plane. Each TO will be served with a four (4) pair 100 ohm Class E cable. The 8 position modular connector must be capable of supporting intermittent use of 6 position modular plugs.

Tamper Proof Faceplates Tamper proof faceplates can be either shuttered outlets or be fitted with a protective cover or insert. The shutter mechanism must form part of the faceplate or connector, be internal and spring loaded. The protective cover must be attached such that a tool is required for its removal. Tamper proof outlets are mandatory in all School locations and TAFE Computer Rooms. The insert must be only removable by the use of a tool. The supply of the tools are to be one tool for every 20 inserts.



Page–33

Labeling All components of the SCS will be labelled with machine printed labels. Hand written labels on panels are not acceptable. Floor Distributor cables and termination panels will be labelled with unique numbers and match the TO numbers. The name of the BD/FD must be attached to the rack and form part of the label for the TO face plate. For a multiple building BD/FD the TO and corresponding patch panel FD outlet must be labelled with the Building name. E.g. the TO may have BD1-F-65; Building Distributor 1 - Building F - TO No. 65 and the Patch Panel will have F-65.

Appendix A DET Patch & Device Leads

UTP Leads The patch looms and device leads specified cater for both Modular Patching. Pair Managed Patch leads can be referred to in early specifications.. The IS3XX series of leads are for higher performing applications. i.e. Fast Ethernet & Gigabit Ethernet Ethernet crossover leads are also provided. The patch looms and device leads are to be manufactured using these specifications as the minimum performance criteria. In all cases they are to comply with “AS/NZS 3087.2:2003 Specification for testing of patch cords in accordance with AS3080” . The modular connectors used will be equivalent to or better than those manufactured by AMP Australia Pty Ltd or Panduit – PANPlug as specified. No lead is to be longer than five meters unless written authority is provided by DET ITD.

Packaging

Patch Looms Patch looms are to be packed separately in clear plastic bags.

Device Leads Device leads are to be packed in lots of ten (10) in clear plastic bags.



Page - 44 -

Optical Fibre Leads Optical fibre leads used in DET will vary in the type of connectors used. However in general the construction and operation are the same. There are numerous older sites which contain ST connectors whilst the new sites use SC connectors at the distributors. Recent active equipment manufacturers are using the small form factor (SFF) connectors which can be the LC and MTRJ connectors.

Construction

Optical fibre leads will be constructed using duplex cordage. Leads that are used within the distributor cabinet can use cordage with a single PVC jacket. Leads that are used external to the cabinet will use a double jacket cordage to provide greater physical protection. The connectors are to be detached from each other and the duplex cordage is to be split for 100mm (minimum) back from the connectors. This is to allow the cross-over of connectors to attain the correct polarity. Easily detachable duplexing clips may be used. SFF connectors such as MTRJ and Volition contain both optical fibre cores in one connector. Thus cross-overs are to be performed at the distributor connector.

Labelling & Markings All leads are to be labelled or marked with

• a manufacturers name • the attenuation loss of each connector • polarisation of connectors and lead • serial numbers are optional

Cleanliness & Operation All connectors are to be cleaned prior to mating connectors. Cleaning equipment specifically designed for cleaning optical fibre connectors are to be used.

Cleanliness & Packaging All connectors on leads and in the patch panels are to be fitted with caps when not in use. Leads are to be stored within sealed plastic bags. Care is to be taken not to exceed the bend radius or exert undue force on the cable.
