7.2.2 Connecting Multi-carrier Interconnection RF Cables

If a double-carrier & single-sector micro-BTS/remote station is required, two cabinets
need be configured. These two cabinets should be connected by cables to achieve
transmission of diversity antenna signals.
When a micro-BTS cabinet and a remote station cabinet form a double-carrier &
single-sector micro-BTS system, two pieces of RF cables need be added to
cross-connect the RFE-ANT0 interface with the EXTEND interface at the bottom of
the two cabinets respectively.
Similarly, when two double-carrier remote station cabinets form a double-carrier
remote station and it is used in cooperation with a double-carrier macro-BTS, two
pieces of RF cables need be added to cross-connect the RFE-ANT0 interface with the
EXTEND interface at the bottom of the two cabinets respectively.
Refer to Appendix B for the configuration of internal cables in a double-carrier system.
The interconnection RF cable is 3m long, with both ends being RF N connectors. It is a
finished product delivered with cabinets. It is named as "F-RF05-009". See Fig. 7.2-6
for the cable connections between two cabinets.
the LFM, lay the optical fiber along the horizontal cabling trough on the top of
the TRX layer, and then along the vertical cabling trough on the left of the shelf;
next, open the cover of the standby interface marked with "BTM ANT" on the
top of the macro-BTS, pull the optical fiber out of the shelf and then lay it onto
the cabling rack on top.
Requirements for laying optical fiber
The optical fiber should be arranged in order, with the interval for cable ties less
than 0.5m.
The minimum bending radius of the outdoor-type optical fiber is 90mm, and that
of the indoor-type optical fiber is 30mm.
