A1751A DWDM Analog
Forward-Path or Return-Path Laser Modules
Data Sheet, Rev. 4
June 2001
Agere Systems Inc.
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 operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
* The device can withstand continuous exposure to the specified limits without damage.
Characteristics
1. Tested in a 50
resistively matched system.
2. Eight channel loading with 10% OMI and 40 km fiber length.
3. Measured at 42 MHz.
4. Measured at 553.25 MHz, 577.25 MHz, and 595.25 MHz.
5. Change in wavelength as case temperature is changed.
