17.1 INTRODUCTION
The RFL 93B FT/FR single width fiber optic transceiver module (Figure 17-1) consists of a fiber optic transmitter
and a fiber optic receiver housed in a single 1.4 inch wide module. For this reason it is referred to as a single
width transceiver module.
The transmitter section accepts signals generated by the RFL 93B CC Communications Controller module
(Section 13) and conditions them for optic transmission. A transmitter output monitor on the module will activate
an alarm if transmitter power is lost.
The receiver section accepts inputs from a fiber optic I/O module (Section 18) and converts them back into RS-
422 signals that can be processed by the RFL 93B CC Communications Controller module (Section 13).
