Optical transmission system

摘要

To compensate for the non-linear conversion characteristic of the laser diode of an optical transmitter, a linearization circuit is provided which includes the combination of a first circuit including a zener diode and a second circuit including an impedance element. The zener diode is biased to provide a non-linear operating impedance such that the impedance of the combination varies substantially inversely to variations of the non-linear conversion characteristic of the laser diode at different signal levels.
