The data “0” output optical power is
compared to the data “1” peak output
optical power and expressed as a
percentage. With the transmitter driven by
a 12.5 MHz square-wave signal, the
average optical power is measured. The
data “1” peak power is then calculated by
adding 3 dB to the measured average
optical power. The data “0” output optical
power is found by measuring the optical
power when the transmitter is driven by a
logic “0” input. The extinction ratio is the
ratio of the optical power at the “0” level
compared to the optical power at the “1”
level expressed as a percentage or in
decibels.
