Its range of standard-to-enhanced performance specifications and available output power ensures the flexibility a CATV system designer needs to accurately and cost-effectively address the requirements of any forward-path application. Features OC-48 pinout compatible Negative bias 112 channel loading available Meets Telcordia Technologies* 468 specifications Output power, up to 13 mW Applications 1310 forward path Broadcast and narrowcast networks * Telcordia Technologies is a trademark of Telcordia Technologies, Inc. Data Sheet, Rev. 4 June 2001 A1611A/B DFB Laser Modules 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 operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
