1. General
SLT2070-xN Series are 1.3µm InGaAsP/InP MQW-FP 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 short reach and
intermediate reach of up to 622Mbps transmission applications.
A laser diode is mounted into a
φ3.8mm
coaxial package integrated with an InGaAs monitor PD, a
singe-mode fiber-stub and a split sleeve for the optical connector with
φ1.25mm
ferrule.

6. 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.
