Subcarrier TX Power is used for the communications and control signaling of the DAS.
 Default setting is -10dBm for single port FOI cards and 0dBm for the 4-port F
OI card.
 The value may need to be changed in situations where fiber loss is near the maximum
and communications issues arise. Unnecessarily increasing the subcarrier TX power
may affect RF performance of the DAS.
