3.3.1.1.1 Power Supply Module
Power Supply Module provides stable power to fiber CM-BTS unit. Power Supply Module is supplied with
110/220V AC.
3.3.1.1.2 Multiplexer & Duplexer
The multiplexer separates the various band frequencies respectively. The duplexer is used to make the
bi-directional signals into simplex signals and provides sufficient isolation.
3.3.1.1.3 RF-Optic Transceiver
The RF-Optic Transceiver is an optical module providing conversion between RF signals and optical signals
over a single fiber. The optical module converts the downlink optical signal from the FIU module in the host
unit, and it also converts the uplink RF signal to an optical signal and simultaneously sends it back to FIU
module in the host unit for distribution to the BIU modules. A laser and received optical power monitor and
alarm are provided.
