4.1.3 RF Connection Between Master Unit and Interface Unit
RF connection between Master Unit (figure 4.1- 1: 1) and Interface Unit
(figure 4.1- 1: 2 ) should be done with upper and lower parts corresponding with
each other: 6 with 7 and 5 with 8. 4 pairs of fiber-optic connectors (SC
optical flange)-EOWN OPOUT (figure 4.1- 1: 9)/UP OPIN (figure 4.1- 1: 10) are
on the panel of the Interface Unit. Connect the uplink and downlink optical
fibers from the coverage end with these fiber optic connec\ctors. In connecting
fiber optic connector, never face it toward people’s eyes and skin since laser
beam may hurt people’s eyes and skin.
4.1.4 Check Ports
There are two pairs of RF connectors on the panel of the Master Unit:
One pair is GSM TEST (figure 4.1- 1:23-uplink RF output, 22-downlink RF
input) and the other is 1800 TEST (figure 4.1- 1:21-uplink RF output,
20- downlink RF input). They are the check ports for GSM and 1800 uplink
and downlink RF signal debug.
