Preliminary Data Sheet, Rev. 4

R192P OC-192/STM-64 Lightwave Receiver

June 2001

with Improved Sensitivity (–18 dBm)

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute 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 section of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.

* Device is normally reverse biased. Forward biasing the photodiode can compromise device performance and reliability.
