Part No.: Document No.: Data of issue: SLT2420-xN-xnnnx Series HUW9924209-01D January 18, 2001 1. General SLT2420-xN-xnnnx Series are 1.47m~1.61m InGaAsP/InP MQW-DFB laser diode modules designed for fiber optic communication systems. These modules are transmitter optical sub-assembly with low threshold current and high performance at high temperature, and are ideally suitable for CWDM of 622Mbps or 2.5Gbps transmission applications. A laser diode is mounted into a f5.6mm coaxial package integrated with an InGaAs monitor PD, a singe-mode fiber-stub and a split sleeve for the SC optical connector. 2.

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) Please pay special attention to the atmosphere condition because the dew on the module may cause some electrical damages. (4) Under such a strong vibration environment as in automobile, the performance and reliability are not guaranteed.
