9. The Extinction Ratio is a measure of the
• At the end of one meter of noted optical
modulation depth of the optical signal. The
data “1” peak output optical power is
compared to the data “0” output optical
power and expressed in decibels. With the
transmitter driven by a 25 MBd (12.5 MHz
square-wave) input signal, the average
optical power is measured. The data “1”
peak power is then calculated by adding
3dB 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 “1” level
compared to the optical power at the “0”
level expressed in decibels.
fiber with cladding modes removed.
The average power value can be
converted to a peak power value by
adding 3 dB. Higher output optical
power transmitters are available on
special request.
