Data Sheet January 2001 A1112 High-Power 1550 nm DFB Source Lasers Description The A1112 1550 nm DFB laser modules are highpower devices in a 14-pin butterfly package with a thermoelectric cooler and monitor photodiode. The lasers are designed to be used in conjunction with commercially available external modulators for highperformance analog and digital applications. Agere Systems Inc. offers modules with 30 mW or 40 mW output power coupled into polarization-preserving fiber. The A1112 operates with positive or negative bias. Features ■ High fiber-coupled power, 30 mW and 40 mW ■ Narrow linewidth, <3 MHz ■ Low relative intensity noise, < –162 dB/Hz ■ Coupled to polarization-preserving (PANDA-type fiber) Applications ■ Externally modulated CATV transmitters ■ Externally modulated analog and digital communication links Data Sheet January 2001 A1112 High-Power 1550 nm DFB Source Lasers 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.
