Data Sheet
February 2001
A1750A DWDM Analog
Forward-Path or Return-Path Laser Module
Characteristics
(continued)
1. Bias point at which all specifications apply.
2. For 10 mW output power. Minimum slope efficiency is lower for lower power lasers.
3. Chip temperature at which wavelength specification is met. Operating chip temperature is reported for each laser.
