Issue 04 (2010-04-20)

Figure 1-1 Wearing an ESD wrist strap

1.3 Flammable Air Environment

DANGERDo not place or operate the equipment in an environment where flammable gas, explosive gas,or smog exists.

Operations on any electronic device in an environment where explosive gas exists may causeextreme risks.

1.4 Radiation

Electromagnetic Exposure

CAUTIONHigh-intensity RF signals are harmful to the human body.

If multiple transmit antennas are installed on the iron tower or backstay, you must request therelevant personnel to shut down the transmit antenna before installing or maintaining the antennalocally.

During the operation, the radio equipment may generate electromagnetic radiation (namely,radiation harm). Before installing and operating the radio equipment, read the guidelines toensure safe operations. When installing the radio equipment, obey the local rules and regulations.



1-5

Forbidden Area

The following requirements should be met:

l The site of the antenna should be far away from the area where the electromagnetic radiationis beyond the specified range and the public cannot reach.

l Before entering the area where the electromagnetic radiation is beyond the specified range,the operator should learn about the area and shut down the electromagnetic radiator. Thearea where the electromagnetic radiation is beyond the specified range, if any, should bewithin 10 meters away from the antenna.

l A physical barrier and an eye-catching warning flag should be available in each forbiddenarea.

Laser

CAUTIONWhen handling optical fibers, do not stand close to, or look into the optical fiber outlet directlywith unaided eyes.

Laser transceivers are used in the optical transmission system and associated test tools. Becausethe laser transmitted through the bare optical fiber produces a small beam of light, it has the veryhigh power density and is invisible to human eyes. When a beam of light enters the eyes, theretina may be damaged.

In normal cases, viewing an un-terminated fiber or a damaged fiber with the unaided eye atdistances greater than 150 mm does not cause eye injury. Eye injury may occur, however, if anoptical tool such as a microscope, magnifying glass, or eye loupe is used to view the bare fiberend.

To avoid laser radiation, read the following guidelines:

l All the operations should be performed by authorized personnel who have completed theapproved training courses.

l Wear a pair of eye-protective glasses when you are handling lasers or fibers.

l Ensure that the optical source is switched off before disconnecting optical fiber connectors.

l Do not look into the end of an exposed fiber or an open connector when you are not surewhether the optical source is switched off.

l Use an optical power meter to check and ensure that the optical source is switched off bymeasuring the optical power.

l Before opening the front door of an optical transmission equipment, ensure that you arenot exposed to laser radiation.

l Do not use an optical tool such as a microscope, a magnifying glass, or an eye loupe toview the optical connector or fiber that is transmitting optical signals.

Read the following instructions before handling fibers:

l Cutting and splicing fibers must be performed by the trained personnel only.




Issue 04 (2010-04-20)

l Before cutting or splicing a fiber, ensure that the fiber is disconnected from the opticalsource. After disconnecting the fiber, connect the cover caps to the fiber connectors.

1.5 Working at Heights

CAUTIONWhen working at heights, be cautious to prevent objects from falling down.

The requirements for working at heights are as follows:

l The personnel who work at heights must be trained.

l The operating machines and tools should be carried and handled safely to prevent themfrom falling down.

l Safety measures, such as wearing a helmet and a safety belt, should be taken.

l Wear cold-proof clothes when working at heights in cold areas.

l Check all lifting appliances thoroughly before starting the work, and ensure that they areintact.

Weight Lifting

CAUTIONDo not enter the areas under the jib arm and the goods in suspension when lifting weight.

l Ensure that the operators have completed the related training and have been certified.

l Check the weight lifting tools and ensure that they are intact.

l Lift the weight only when the weight lifting tools are firmly fixed onto the weight-bearingobject or the wall.

l Use a concise command to prevent any incorrect operation.

l Ensure that the angle between the two cables is less than or equal to 90 degrees during thelifting, as shown in Figure 1-2.

4.4 Aligning the AntennasAligning the antennas is the most important activity in HOP commissioning, and its result hasa direct effect on the performance of the radio link.

4.4.1 Main Lobe and Side LobeBefore you align the antenna, you should be familiar with the related knowledge of the mainlobe and side lobe.

4.4.2 Aligning the Single-Polarized AntennasWhen you align the single-polarized antennas, you need to align the main lobes of the antennaby adjusting the azimuth and elevation of the antennas at both ends.

4.4.3 Aligning the Dual-Polarized AntennasWhen you align the dual-polarized antennas, you need to align the main lobe of the antennasignals by adjusting the azimuth and elevation of the antennas at both ends. You also need toadjust the feed booms of the antennas so that the cross-polarization discrimination (XPD) meetsthe specified requirements.

4.4.1 Main Lobe and Side LobeBefore you align the antenna, you should be familiar with the related knowledge of the mainlobe and side lobe.

Definitions of the Main Lobe and Side LobeThe electric field strength of the radiated power of the antenna varies in space. The differencesof the power distribution can be shown in an azimuth diagram. Generally, there are the horizontal




Issue 04 (2010-04-20)

azimuth diagram for the horizontal section and the vertical azimuth diagram for the verticalsection. Figure 4-7 is a vertical azimuth diagram. There are many lobes in this figure. The lobewith the strongest radiated power is the main lobe. The other lobes are side lobes wherein thefirst side lobe can be used for aligning the antenna.

Figure 4-7 Main lobe and side lobe

Main lobe

First side lobeSecond side lobe

Locating the Main LobeThe antenna alignment involves making the main lobe of the local antenna aligned with the mainlobe of the opposite antenna. The purpose is to make the received signal strength of the oppositeantenna reach the maximum value.

The main lobe width of the microwave antenna is narrow, that is, between 0.6° and 3.7°. Forinstance, in the case of a 1.2 m antenna at the working frequency of 23 GHz, the azimuth is only0.9° when the signal level drops from the signal peak to zero. Once a signal is detected, verysmall alignment adjustments are required to locate the main lobe.

Antenna movement across the main lobe results in a rapid rise and fall of signal level. Whetherthe main lobe is aligned properly can be verified by comparing the received signal peaks.Typically, the main lobe signal peak is 20-25 dB higher than the first side lobe signal peak.

Figure 4-8 shows the head-on view of a free-space model for radio propagation with concentricrings of side lobe peaks and troughs radiating outward from the main lobe.

l Line AA' represents that the main lobe of the antenna is almost aligned properly. The mainlobe is at point 2, and the first side lobes are at points 1 and 3. Slightly adjust the azimuthof the antenna at point 2 until the peak signal appears.

l Line BB' represents that the elevation of the antenna slightly deviates from the main lobe.The signal peaks appear at points 4 and 5. The signal peak at point 4 is higher than thesignal peak at point 5 because of the antenna characteristics. As a result, point 4 may bemistaken for the peak point of the main lobe signal. The correct method is to set the azimuthof the antenna to the middle position between the two signal peaks. Then, adjust theelevation of the antenna until the three signal peaks of line AA' appear. Slightly adjust theelevation and azimuth of the antenna at point 2 until the peak signal appears.

l Line CC' represents that the elevation of the antenna completely deviates from the mainlobe and is almost aligned with the first side lobe. The signal peak of the first side lobe atpoint 6 and the signal peak of the first side lobe at point 7 appear as one signal peak. As aresult, points 6 and 7 may be mistaken for the peak point of the main lobe signal. The correctmethod is to set the azimuth of the antenna to the middle of points 6 and 7. Then, adjustthe elevation of the antenna until the three signal peaks of line AA' appear. Slightly adjustthe elevation and azimuth of the antenna at point 2 until the peak signal appears.

When the side lobe peak at one side is higher than the side lobe peak at the other side, as shownin Figure 4-10, a common error is to move the antenna left to right along line DD', or top tobottom along line EE'. As a result, point 1 may be mistaken for the peak point of the main lobesignal. The correct method is to adjust the elevation in the middle of points 1 and 2 or the azimuthin the middle of points 1 and 3. Several adjustments are required so that the three signal peaksof line AA' can appear. Slightly adjust the elevation and azimuth of the antenna at point 2 asshown in Figure 4-9 until the peak signal appears.

2. At both ends, power off the main ODUs, power on the standby ODUs, and align thediversity antennas.

CAUTIONYou can adjust the azimuth and elevation of the antennas by adjusting the related nuts or screws.For details, see the related installation guide.

ProcedureStep 1 Determine the azimuth of the antenna according to the installation position and height of the

antenna. Then, adjust the elevation of the antenna to the horizontal position.

Step 2 Connect a multimeter to the received signal strength indicator (RSSI) port on the ODU at thelocal end and test the voltage value VBNC.




Issue 04 (2010-04-20)

TIP

It is recommended that you make the test line terminated with a BNC connector at one end in advancebecause it is more convenient to test the voltage value VBNC.

Step 3 Adjust the azimuth and elevation of the antenna as follows:

1. Keep the remote antenna fixed.

2. Use the multimeter to measure the VBNC. At the local end, rotate the antenna widely in thehorizontal direction.When you rotate the antenna, the tested signal peaks may be as follows:

l Three signal peaks are tracked, for example, line AA' in Figure 4-9. In this case, adjustthe azimuth of the antenna to the peak position at point 2 as shown in Figure 4-9.

l Two signal peaks are tracked, for example, line BB' in Figure 4-9. In this case, adjustthe azimuth of the antenna to the middle of points 4 and 5 as shown in Figure 4-9. Then,adjust the elevation of the antenna so that the three signal peaks in the case of line AA'can appear. Adjust the antenna to the peak position at point 2 as shown in Figure 4-9.

l One signal peak is tracked, for example, line CC' in Figure 4-9. In this case, adjust theazimuth of the antenna to the middle of points 6 and 7 as shown in Figure 4-9. Then,adjust the elevation of the antenna so that the three signal peaks in the case of line AA'can appear. Adjust the antenna to the peak position at point 2 as shown in Figure 4-9.

3. Slightly adjust the elevation and azimuth at point 2 as shown in Figure 4-9 until theVBNC reaches the peak within the tracked range.

4. Adjust the antenna until the VBNC voltage reaches the peak value. Then, fix the antenna atthe local end.



4-31

NOTEWhen you tighten the antenna, ensure that the VBNC voltage remains the peak value.

Step 4 Repeat Step 2 to Step 3 to adjust the antenna at the remote end. When the VBNC reaches thepeak value, tighten the antenna at the remote end.

Step 5 Repeat Step 2 to Step 4 for two to four times. When the VBNC at the local end and the VBNC atthe remote end reach the peak value, tighten the antennas at both ends

Step 6 Use the multimeter to test the VBNC voltage at both ends. Obtain the current RSL by referringto the relation curve between the VBNC of ODUs and the RSLs at both ends.

NOTE

The curve diagram of the VBNC and RSL is delivered in the carton of the ODU.

The actual RSL must be the same as planned by the network planning department.

NOTE

l If the VBNC does not meet the requirements, see the OptiX RTN 950 Radio Transmission SystemMaintenance Guide for handling the fault.

Step 7 Observe the ODU indicator on the IF board. The ODU indicator should be off. If the ODUindicator blinks yellow, align the antennas.

Step 8 Tighten all the screws of the antennas.

NOTE

Use the multimeter to measure the received value of RSSI. Avoid any fault in the alignment of antennas in theprocess of tightening the screws.

Thisprotocol manages and controls the multicast group by listening to andanalyze the Internet Group Management Protocol (IGMP) packet betweenhosts and layer 3 devices. In this manner, the spread of the multicast dataon layer 2 network can be prevented efficiently.

L

Layer 2 switch A data forwarding method. In LAN, a network bridge or 802.3 Ethernetswitch transmits and distributes packet data based on the MAC address.Since the MAC address is the second layer of the OSI model, this dataforwarding method is called layer 2 switch.

LCT The local maintenance terminal of a transport network, which is locatedon the NE management layer of the transport network.

Linkaggregationgroup

An aggregation that allows one or more links to be aggregated together toform a link aggregation group so that a MAC client can treat the linkaggregation group as if it were a single link.

Trail A type of transport entity, mainly engaged in transferring signals from theinput of the trail source to the output of the trail sink, and monitoring theintegrality of the transferred signals.

M

Multiplexsectionprotection

The function performed to provide capability for switching a signalbetween and including two MST functions, from a "working" to a"protection" channel.

MultipleSpanning TreeProtocol

MSTP is an evolution of the Spanning Tree Protocol and the RapidSpanning Tree Protocol, and was introduced in IEEE 802.1s as amendmentto 802.1Q, 1998 edition. Standard IEEE 802.1Q-2003 now includesMSTP.

N

N+1 protection A microwave link protection system that employs N working channels andone protection channel.

Networkelement

A network element (NE) contains both the hardware and the softwarerunning on it. One NE is at least equipped with one system control boardwhich manages and monitors the entire network element. The NE softwareruns on the system control Unit.

Networkmanagementsystem

The network management system in charge of the operation,administration, and maintenance of a network.

Non-gatewaynetworkelement

A network element whose communication with the NM application layermust be transferred by the gateway network element application layer.

O

Orderwire A channel that provides voice communication between operationengineers or maintenance engineers of different stations.

Outdoor unit The outdoor unit of the split-structured radio equipment. It implementsfrequency conversion and amplification for RF signals.

P

PlesiochronousDigitalHierarchy

A multiplexing scheme of bit stuffing and byte interleaving. It multiplexesthe minimum rate 64 kit/s into the 2 Mbit/s, 34 Mbit/s, 140 Mbit/s, and 565Mbit/s rates.

Polarization A kind of electromagnetic wave, the direction of whose electric field vectoris fixed or rotates regularly. Specifically, if the electric field vector of theelectromagnetic wave is perpendicular to the plane of horizon, thiselectromagnetic wave is called vertically polarized wave; if the electricfield vector of the electromagnetic wave is parallel to the plane of horizon,this electromagnetic wave is called horizontal polarized wave; if the tip ofthe electric field vector, at a fixed point in space, describes a circle, thiselectromagnetic wave is called circularly polarized wave.
