The transmitter power and receive sensitivity levels listed in Table B-1
represent Peak Power Levels after optical overshoot. You must use a Peak
Power Meter to correctly compare the above values to those you measure
on any particular port. If you measure Power Levels with an Average
Power Meter, you must add 3 dBm to the measurement to correctly
compare measured values to the values listed in Table B-1
(e.g., -29.5 dBm peak = -32.5 dBm average).

Transmitter power is inversely proportional to temperature rise. Use the
Output Power Coefficient to calculate increased or decreased power
output for your operating environment. For example, typical power output
at 25˚C equals -16.4 dBm. For a 4˚C temperature increase, multiply the
typical coefficient (-0.15 dBm) by four, and add the result to typical
output power (4 x -0.15 dBm + -16.4 dBm = -17.0 dBm).
