General SLT4400-xx-S850 Series and SLT4460-xx-S850 Series are 1.51m InGaAsP/InP MQW-DFB laser diode modules designed for fiber optic communication systems. These modules are ideally suitable for long reach and intermediate reach of up to 622Mb/s transmission applications. A laser diode is mounted into a coaxial package integrated with an InGaAs monitor PD and a single mode fiber pigtail. Especially SLT4460-xx-S850 Series have a single stage isolator integrated inside. 2. Package dimension and pin assignment (See attached appendix.) 3.

Precaution (1) Radiation emitted by laser devices can be dangerous to the eyes. Avoid eye or skin exposure to direct or scattered radiation. (2) The modules should be handled in the same manner as ordinary semiconductor devices to prevent the electro-static damages. For safe keeping and carrying, the modules should be packaged with ESD proof material. To assemble the modules on PCB, the workbench, the soldering iron and the human body should be grounded. (3) The stress to the fiber pigtail may cause the damage on the performance. The fiber pigtail may snap off by dropping the module. (4) Please pay special attention to the atmosphere condition because the dew on the module may cause some electrical damages.
