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 2.5 Gbps transmission applications.
A laser diode is mounted into a
φ
3.6mm coaxial package integrated with an InGaAs monitor PD, a
singe-mode fiber-stub and a split sleeve for the optical connector with
φ
1.25mm ferrule.

Data of issue:
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.
