	100/140 ∝m	-7.0 dBm	-9.0 dBm	19.0 dB	23.5 dB

Error Rate: Better than 10-10

The transmitter power and receive sensitivity levels given in Table A-2 are Peak Power Levels after optical overshoot. A Peak Power Meter must be used to correctly compare the given values to those measured on any particular port. If Power Levels are being measured with an Average Power Meter, then 3 dBm must be added to the measurement to correctly compare those measured values to the values listed in Table A-2 (i.e. -30.5 dBm peak=-33.5 dBm average).
