Note The optical splitters to be used are single fiber splitters. As each traffic line has two fibers, two splitters for each traffic line must be used. The max number of splitters that can be allocated inside the connection box is four so the maximum traffic configuration allowed for each ODU is: 2 SDH lines, 2 Eth lines or 1 SHD + 1 Eth lines.

Note The conduit for ODU to ODU connection cabling has to be 1m long to allow for routing the 1.7m MM or SM fibers (see Table 15. on page 137). The conduits from connection box to ODUs have to be cut to the correct length depending on the installation constraints. The maximum length cannot exceed 2 meters.

4 Place the front plate 5 The front plate has a proper receptacle for optical splitters and for LC-LC adapters. Put the optical splitters into the receptacle and fix them through the apposite screwed cover. Place the proper number of LC-LC adapters. Secure the fibers with tie wraps to the hanging hooks present in the front plate.

6 Connect the outer fibers connectors (see next section).

6.8.10.2 Protection active and standby radio cabling

All data cabling is installed on matching ports between the active and standby radios using fiber splitters. Protection communication between the active and standby radios requires a dedicated fiber connection between each radio's SDH/SONET Port 3.

The following instructions assume:

– For in-band management, a fiber connection is used between an Ethernet port on the active radio and the same number Ethernet port on the standby radio for management.

– For out-of-band management, separate Cat5e cables from the Copper 9 ports on the active and standby radios are used for management.

6.8.10.2.1 Protection active and standby radio cabling: example configuration

Active radio cabling

1) Attach one end of a single-mode fiber cable, with LC connectors, to SDH/SONET Port 3 on the active radio. The other end will eventually be connected to SDH/SONET Port 3 on the standby radio, to communicate protection-related information between the radios.

2) If desired, attach one end of a single-mode fiber cable, with LC connectors, to SDH/SONET Port 1 on the active radio, for SDH/SONET data. Another fiber cable will eventually be connected to SDH/SONET Port 1 on the standby radio. These cables will eventually be terminated in a fiber splitter inside a connection box. A third fiber cable will eventually go from the fiber splitter to customer equipment. For additional SDH/SONET data connections, repeat for SDH/SONET Port 2. SDH/SONET Port 4 can also be used for radios without Sync-E.

3) For Sync-E radios, attach one end of a single- or multi-mode fiber cable, with LC connectors, to SDH/SONET Port 4 on the active radio for Sync-E data. Another fiber cable will eventually be connected to SDH/SONET Port 4 on the standby radio. These cables will eventually be ter- minated in a fiber splitter inside the connection box mentioned above. A third fiber cable will eventually go from the fiber splitter to customer equipment.

4) Attach one end of a single- or multi-mode fiber cable, with LC connectors, to the desired Ether- net data port on the active radio. Another fiber cable will eventually be connected to the same- numbered (matching) Ethernet data port on the standby radio. These cables will eventually be terminated in a fiber splitter inside the connection box mentioned above. A third fiber cable will eventually go from the fiber splitter to customer equipment. Repeat for each Ethernet data con- nection. For out-of-band management, four Ethernet fiber data connections can be used; for in-band management, three Ethernet fiber data connections can be used.

5) For in-band management, attach one end of a fiber cable to an Ethernet port on the active radio. The other end will eventually be connected to the same-numbered Ethernet port on the standby radio.

For out-of-band management, attach one end of a Cat5e cable to the Copper Port 9 on the active radio.

6) Route the fiber cables used for in-band management (if applicable) and protection communi- cation through the straight-through fitting, then attach the flexible conduit to the fitting, ensuring that the cables do not get pinched when the conduit is pushed on to the fitting. Route these cables, which will connect to the standby radio, through this conduit.

7) Install the power cabling on the active radio. Refer to the Power Cabling subsection.

8) Route the following cables through the other straight-through fitting: fiber cables for data and Sync-E, Copper 9, and power. Then, attach the flexible conduit to the fitting. Route these cables, which will connect to the connection box, through this conduit.

Standby radio cabling

1) Attach the end of the cable from SDH/SONET Port 3 on the active radio to SDH/SONET Port 3 on the standby radio (protection communication).

2) If using SDH/SONET Ports 1, 2, or 4 for data, attach one end of a single-mode fiber cable with LC connectors, for each applicable SONET/SDH port, on the standby radio. These connec- tion(s) should match the SDH/SONET port(s) used on the active radio. These cables will even- tually be terminated in a fiber splitter inside the connection box.

3) For Sync-E radios, attach one end of a multi-mode fiber cable with LC connectors, to SDH/ SONET Port 4 on the standby radio for Sync-E data. This cable will eventually be terminated in a fiber splitter inside the connection box.

4) Attach one end of a single- or multi-mode fiber cable with LC connectors, for each applicable Ethernet port, on the standby radio. These connection(s) must match the Ethernet port(s) used on the active radio. These cables will eventually be terminated in a fiber splitter inside the con- nection box.

5) For in-band management, attach the end of the cable from the Ethernet port on the active radio dedicated for in-band management to the matching Ethernet port on the standby radio. For out-of-band management, attach one end of a Cat5e cable to Copper Port 9 on the standby radio.

6) Install the power cabling on the standby radio. Refer to the Power Cabling subsection. 7) Attach the flexible conduit from the active radio to a conduit fitting on the standby radio, to

enclose the cabling between the active and standby radios (in-band management, if applicable, and protection communication).

8) Route the following cables through the other straight-through fitting on the standby radio: fiber cables for data and Sync-E, Copper 9, and power. Then attach the flexible conduit to the fitting. Route these cables, which will connect to the connection box, through this conduit.

Connection box cabling

2) For each data and Sync-E connection: a) Route the fiber cable from the active radio through one entry of the connection box and attach the fiber cable LC connector to one sleeve of a fiber splitter. b) Route the fiber cable from the standby radio matching port through the other entry of the connection box and attach the fiber cable LC connector to the second sleeve of the fiber splitter. c) Attach a third fiber cable with an LC connector to the third sleeve of the fiber splitter to eventually be routed from the connection box exit to customer equipment.

Use one multi-mode fiber splitter per matching Ethernet or Sync-E port, and one single-mode fiber splitter per matching SONET/SDH port.

3) For out-of-band management, a) Route the cable from the active radio Copper 9 port through the connection box entry designated for the active radio. b) Route the cable from the standby radio Copper 9 port through the connection box entry designated for the standby radio. 4) Route the power cable from the active radio through the connection box entry designated for

the active radio; route the power cable from the active radio through the connection box entry designated for the standby radio.

5) Attach flexible conduit to both connection box entries.

6) Route the following cables through the connection box exit: data and Sync-E fiber cables from the third sleeve of the fiber splitters, Copper 9 port, and power.

7) Attach flexible conduit to the connection box exit.

8) Connect the fiber and Cat5e cables at the customer equipment.

It is recommended to secure the fiber splitters inside the connection box using a tie wrap.

6.8.10.3 OMT-80 fiber cabling

1) Install the desired SFP modules in the radio with duplex MMF or SMF fiber from the radio to the network termination equipment (switch or router with 1000Base-X port or SONET/SDH equipment). The cable should be looped around the inside of the enclosure to provide strain- relief. The connectors on the radio end of the fiber require a duplex LC connector; the connec- tors on the switch/router end should mate to the network equipment.

2) Connect the fibers at the network equipment.

6.8.10.4 Power cabling

Please refer to the Power Cabling subsection.

6.8.10.5 Ground cabling

The preferred method for grounding the radio is to ground the mast to a ground source. If this is not pos- sible, perform the following:

1) Insert the ground cable into the grounding hole of the radio and tighten the 9/16 inch grounding bolt to hold the ground cable.

2) Connect the other end of the ground cable to a nearby ground location.

6.8.10.6 10/100/1000 Base-T surge suppressor

It is recommended to use a surge suppressor at the point where the cable enters a building or is connected to other outdoor equipment that does not already contain surge suppression hardware.

6.8.10.7 RSL test cable

Please refer to the RSL Test Cable subsection.

The following summarizes surge suppressor cabling. For details, refer to the 10/100/1000 Base-T Surge Suppressor subsection.

When removing the cover of the radio to measure voltage, open the clasp nearest the antenna last. When replacing the cover, close the clasp nearest the antenna last.
