Abstract
A calibration circuit for a linear channel of an optical modem includes circuitry interconnected to the linear channel for causing the linear channel to oscillate. Circuitry is interconnected to the output of the linear channel for monitoring the bandwidth of the linear channel during oscillation and for generating output pulses. The output pulses are counted and are utilized for generating an adjustment signal applied to the linear channel for adjusting the bandwidth of the linear channel.
