Solution: one 8-way HDPE bundle Micro duct

Length: 140KM

Duration:11months

Max progress :25 km/month

After the excavation, a 7-way bundle micro duct

had been laid into the trench, and after the laying

of the micro duct, a 48 core micro cable had been

blowing into the micro duct. Because the total

diameter of the micro duct is less than 45mm, so

the excavation width is only 300mm.

INTORDUCTIONTo cater the ever increasing demand for Bandwidth and to achieve a “high reliable core network”, Dialog decided to expand its Optical Fibre network.

Hence new fibre routes and nodes were identified according to the existing and predicted capacity requirements as well as the identified strategic potentials.

This decision drove Dialog for the option of releasing a Request for Proposal (RFP) to look for bidders who propose solutions for the requirement.

This section covers the technical requirements and expectations of the project.

General Scope

The scope of this document is to describe the Technical Requirements & Specifications that the Bidders shall fulfil with the aim to

provide a complete end to end solution for the implementation of Optical Fibre Network as a turnkey project.

TECHNICAL REQUIREMENTS SPECIFICATION (TRS)

The TRS specifies the technical requirements to be fulfilled in order to implement a complete end-to-end solution

for the Optical Fibre Network.

Following will be key points for the bidders to adhere from the beginning of the project.

•This is an extension of Dialog’s existing Optical Fibre Network (OFN). Hence all the components and solutions proposed by bidders

will be assessed for the compatibility with the existing network and same will be treated as a must.

•The base of the cable network will be aerial and the solution should be designed in a manner that the cable implementation to be

aerial as much as possible. The scenario to choose the other options is described under the civil construction module.

•Dialog reserves the right to suggest the successful bidder/s to change and propose any of the network / project components described

under TRS. Bidders are expected to take this challenge from the beginning.

•Dialog will decide and change its priorities on implementation with respect to the fibre routes even while at the implementation

phase.

Proposal: ADSS is recommended for installation on existing electric pole, but the

existing electric pole and wire height should be considered.

Advantage Disadvantage

ADSS ADSS cable has higher tensile strength. It isapplicable for long span. The overall thermalexpansion coefficient of ADSS is very low, sothe effect of temperature on ADSS sag is small.

ADSS is made of non-metallic materials, canbe installed and maintained on live-linesituation. The feature is convenient and safefor installation and maintenance.

Anti-track material makes ADSS be able to beused in strong electric fields.

ADSS cable has good features, such as smalldiameter, light weight, and small load affectionon poles or towers.

Installed position is under existing electric cable,the safety distance between cable and ground needto be considered.

OPGW Strong Physical feature, can support long spaninstallation (more than 250m).

Suitable for new installation powertransmission system to save construction cost.

Vibration caused by wind, hurricane, ice thickness, Unsteady operation caused by temperature,

possible thunder attack, short circuit. For existing power line system, the power supply

must be break off

Proposal : G.652D is recommended.


G.655 lower dispersion, and it need fewer DCM

(Before DCM is high cost, using G.655 save the cost of DCM. But now the DCM price is lower down, and it is not a significant advantage)

replaced with new

type of OFC

Balance of CAPEX and OPEX

• According to the traditional solution, compared with duct OFC, the direct buried

OFC for the national backbone has low CAPEX, but OPEX is extremely higher.

• Maintenance

• Trouble shooting

• Repair

No need to

excavate again

and again

Expansion

• Different steps: Duct & manhole

• Different installation methodology: laying, blowing, pulling

The distance between the manholes increases to around

1000m compare with 100m in the traditional PVC duct

solution after the popularize of HDPE pipe and cable blowing

technique. The cost of manhole reduces.

Expansion Process

• No expansion capacity for D.B.

• Cable blowing technique makes

• Choose the cable blowing methodology

The cost of HDPE pipe solution is quite lower than the traditional PVC solution. The additional cost of construction is mainly about the pipe and manhole compare with D.B. solution.

Advantage of HDPE pipe solution: obviously the OFC services have higher reliability and cost performance. The outside plant part is more convenient to maintain, and provided with expansion and upgrade capacity.

Microdu

ct

Reduce the initial investment, and

easy for expansion.

Easy to upgrade the fiber cable type.

Fully utilize the existing duct

resource

Easy for branching.

Reduce manhole / handhole

quantities.

High requirement for the protection in

handhole and manhole.

Special tools needed for

implementation and maintainence.

Additional cost for microduct

The advantage is good for access

network and FTTx senario, but for

backbone network, it not obvious.

Proposal: HDPE with blowing installation method solution is proposed.

Depend on the requirement of SMC, Microduct & Microcable or conventional

cable can be considered to be installed inside HDPE duct.
