You must use a Peak Power Meter tocorrectly compare the values given above to those measured on anyparticular port. If you are measuring power levels with an AveragePower Meter, add 3 dBm to the average power measurement tocorrectly compare the average power values measured to the valueslisted above (i.e. -33.5 dBm average + 3 dB = -30.5 dBm peak).ReceiveSensitivitydBmLess Power More Power-40 -35 -30 -25 -20 -15 -10 -5 0MaximumReceiveInput PowerTransmitter Power*(At 25°C into8.3/125μm fiber)Minimum Sensitivity (-30.0)Typical Sensitivity (-31.0)Maximum Sensitivity (-36.0)Maximum Receive Input (-6.99)Typical Receive Input (-7.5)Minimum Receive Input (-9.72)Maximum Transmit Power (-12.0)Typical Transmit Power (-15.5)Minimum Transmit Power (-21.0)* Transmit Power Typical Power Minimum Power Maximum PowerCoefficient(See Note Below)-0.15dBm/ °C -0.12 dBm/ °C-0.18 dBm/ °C
