data “1” peak output optical power and expressed as a percentage.
With the transmitter driven by a HALT Line State (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. T he extinction ratio is the ratio of the optical power at
the “ 0” level compared to the optical power at the “ 1” level expressed

The receiver can be equivalently tested to the worst case FDDI PMD
input jitter conditions and meet the minimum output data window
time-width of 2.13 ns. This is accomplished by using a nearly ideal
input o ptical s ignal (no DCD, i nsignificant DDJ a nd RJ) and m easuring
for a wider window time-width of 4.6 ns. This is possible due to the
cumulative effect of jitter components through their superposition
(DCD and DDJ are directly additive and RJ components are rms ad-
ditive). Specifically, when a nearly ideal input optical test signal is
used and the maximum receiver peak-to-peak jitter contributions
of DCD (0.4 ns), DDJ (1.0 ns), and RJ (2.14 ns) exist, the minimum
window time-width becomes 8.0 ns -0.4 ns - 1.0 ns - 2.14 ns = 4.46
ns, or conservatively 4.6 ns. This wider window time-width of 4.6 ns
guarantees the FDDI PMD Annex E minimum window time-width
of 2.13 ns under worst case input jitter conditions to the Avago
Technologies receiver.
