Transmitter Extinction Ratio

The extinction ratio is the ratio of the average optical power for transmitting signals 1 to the average optical power for transmitting signals 0 under the worst transmission conditions. The extinction ratio may be expressed as a fraction, in dB, or as a percentage. It may be given by where P1 is the optical power level. One parameter, extinction ratio, is used to describe optimal biasing conditions and how efficiently available laser transmitter power is converted to modulation power. 5 dB, the OMAouter (min) must exceed this value.
