The transmitter power levels given in Table A-3 are Peak Power Levels

after optical overshoot. A Peak Power Meter is required to correctly

compare the values given above to those measured on any particular port.

When measuring power levels with an Average Power Meter, add 3 dBm

to the average power measurement to correctly compare the average

power values measured to the values listed in Table A-3 (i.e., -33.5 dBm

average + 3 dB = -30.5 dBm peak).

Fall Time 2.5 nsec 2.2 nsec 5.0 nsec

Duty Cycle 50.1% 49.6% 50.7%

Bit Error Rate: Better than 10
