3.3.3.1 Primary Components
3.3.3.1.1 Optical Modules
The RTM enclosure interior layout, shown in Figure 11, is equipped to interface up to five bands (700MHz,
850MHz, 1900MHz, 2100MHz and 2600MHz). The enclosure includes weatherproof housing, plug in plug in
CM multi-slot chassis and internal multiplexer, RF-optic transceiver, and control unit elements.

3.3.3.1.2 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.
3.3.3.1.3 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.
