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.
