Data Sheet February 2001 A1612A/B 1310 nm Forward-Path DFB Laser Modules Description The A1612A/B 1310 nm forward-path DFB laser modules are designed for both broadcast and narrowcast analog applications. The highly linear, OC-48 pinout-compatible devices feature up to 31 mW output power with superior distortion performance over an enhanced operating temperature range of –40 °C to + 85 °C. With 31 mW of output power, the A1612A/B module enables transmission beyond 40 km, and a greater number of optical splits. In addition, the wide operating temperature range increases the laser’s reliability even in the harshest environments. Features ■ OC-48 pinout compatible ■ Negative bias ■ 112 channel loading ■ Meets Telcordia Technologies * 468 specifications ■ High output power, up to 31 mW Applications ■ 1310 nm forward path: — Long distances — High-count optical splits ■ Broadcast and narrowcast networks * Telcordia Technologies is a trademark of Telcordia Technologies, Inc. Data Sheet February 2001 A1612A/B 1310 nm Forward-Path 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.
