1310 TX Operation

 The RF input signal is amplified before being converted to an optical

signal using a high-performance, isolated distributed feedback (DFB)

laser.

 The incoming RF signal is also routed through a coupler to an RF detector

circuit. The RF detector produces a DC voltage proportional to incident RF

power that is used to monitor the input power level.
