Working Mode
Description
Normal
：
AGC/MGC
1. Normal is the general working mode. AGC or MGC optional.
2. Select AGC: turn on the optical AGC function, the output level will not vary
with the change of received optical power, its adjustable range is 10dB.
3. Select MGC: turn off the optical AGC function, the output level will vary with
the change of received optical power, its adjustable range is 30dB.
RF OutPut SWx

menu. There is no this menu under the RFOG mode.
RFOG
1. RFOG is the burst working mode. Automatic turn off the optical AGC
function.
2. Under the RFOG mode, there is RF signal output only when input the return
optical signal; otherwise, there is no RF signal output.
