Method for the Control of Extinction Ratio in Optical Transceivers

This paper provides information about Extinction Ratio (ER) which is directly related to Laser Signal Power and Bit Error Rate (BER) in an optical communication channel, and presents it as a key parameter used to specify the reliability of signal transmission in optical transceivers. There have been a variety of methods used to control ER but the paper highlights that the proprietary method for ER control yields superior performance over other methods. This brief discusses the method Company has developed and compares laser performance using the described method to more traditional methods.
