Table 22: Color codes for IF cables
Note:
(1)
For example, if n (X-Pol RBS Tx #) is 5, the number of bands is (2x5)-1, which equals 9 colo-
red bands. A white band is added if the cable attaches to a redundant X-Pol RBS Tx.
(2)
For example, if n (X-Pol RBS Rx #) is 5, the number of bands is (2x5), which equals 10 colo-
red bands. A white band is added if the cable attaches to a redundant X-Pol RBS Rx.
Figure 31 shows an example of a cable marked for identification. According to the bands on the cable
(3 red bands and 1 white band), the cable connects to the second redundant X-Pol RBS Tx in sector B.
Figure 31 – IF cable marked for identification
All IF cables should be marked for identification close to where a cable connector is installed. To simplify
the installation of IF cables, mark the cables as they are being installed at the following points:
– where a cable attaches to the 12:2 Combiner/Splitter,
