1. General
SLT2480-xN-xnnnx Series are 1.27µm~1.61µm InGaAsP/InP MQW-DFB laser diode modules
designed for fiber optic communication systems. These modules are transmitter optical sub-assembly
integrated with a single-stage optical isolator, and are ideally suitable for CWDM of 2.5Gb/s 80km
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.
