A1112 General Description


The A1112 1550 nm DFB laser modules are high- power 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 high- performance 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.
