Description (continued)
The device characteristics listed in this document are
met at 1.0 mW output power. Higher- or lower-power
operation is possible. Under conditions of a fixed photodiode current, the change in optical output is typically
±0.5 dB over an operating temperature range of –40 °C
to +85 °C.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
