HL1328DJS
1.3
µm
InGaAsP Laser Diode
Description
The HL1328DJS is a 1.3
µm
InGaAsP Fabry-Perot laser diode with a multi-quantum well (MQW)
structure. It is suitable as a light source in 155 Mb/s or 622 Mb/s short haul fiberoptic communication
systems and other types of optical equipment. Laser output is delivered from the non-hermetic miniature
DIL package through SC optical connector attached at the end of fiber pigtail. A built-in photodiode
provides monitor current output.
