Setting working point of optical transmitter involves varying feedback signal with reference signal constant until desired working point for optical transmitter has been set

摘要

The method involves the use of a control loop with a feedback signal dependent on the output power of the transmitter (1) and a reference signal. The feedback signal is varied with the reference signal constant until a desired working point for the optical transmitter has been set. The feedback signal is acquired using an optical or electrical measurement device. AN Independent claim is also included for the following: a circuit for implementing the method.
