Avoid turning while laying optical fibers. Route optical fibers as straight as possible.
Lead optical fibers between cabinets through cabling racks, or through the top of
cabinets if convenient.
Put the redundant optical fibers in the fiber tray. Do not cross fibers.
Lay optical fibers naturally. Do not pull or bind them by force. Bind fibers on the
beam every 150 mm (6 in.).
Labels at both ends of optical fibers must be clear. They must indicate the
relationship between the RF module and the fiber port on the BRDM of the
baseband subrack.
Use corrugated plastic tubes to protect fibers when leading them out of the cabling
rack.

5.5.2 Installing Optical Fibers Cascading the ODU3601C

When the ODU3601C is cascaded with the BTS3606A, you need to connect two ends
of the optical fiber respectively to the optical interface of the CCPM on the BTS3606A
and the optical interface of the MTRM on the ODU3601C.

5.6 Installing GPS Lightning Arrester and GPS Clock Cables

The GPS clock cables are bound to the bundling rack near the air intake box upon
delivery.
To install the GPS lightning arrester and GPS clock cables,
1) Remove the panel on the air intake box.
The box already has the GPS clock cable attached as shown in Figure 5-34.
