3)
Connect the other end to the corresponding hole of the protection grounding bar
in the cabinet.
4.4.3 Distributing Protection Grounding Cables for Cabinets
The protection grounding cable for cabinet is distributed in the same way as the
power cable is. See section 4.3.3 , "Routing Power Cables".
4.5 Installing Optical Fibers
When the BTS3606 connects to the ODU3601C, you need to install the optical fibers.
4.5.1 Distribution Principle of Optical Fibers
Observe the following principles when distributing and binding optical fibers:
Do not bend an optical fiber to a right angle upon distribution. Make it round with
a diameter of no less than 8 cm. Optical fiber pairs must be bound in order.
The optical fibers between cabinets can be distributed through the cabling rack,
or directly on the top of the cabinet for the consideration of a nice appearance.
Keep the redundant optical fibers in the fiber management tray. Do not twist and
mix fibers; otherwise, it is difficult to identify them.
Optical fibers must be distributed according to specific conditions and bound
properly. Those fixed onto the beam must be bound with the interval of 150 mm.
Corrugated plastic tubes must be added to protect the fibers when they are led
out of the cabling rack.
4.5.2 Installing Optical Fibers to ODU3601C
When BTS3606 is connected with ODU3601C, optical fibers are led out from CCPMs
to the MTRM of ODU3601C.
4.5.3 Installing Optical Fibers of Combined Cabinets
For details, see 4.8.2 "Installing Optical Fiber".
