1. General
SLT4410 Series and SLT 4460 Ser ies ar e 1.55µm InGaAsP/InP MQW-DFB laser diode modules
designed for fiber optic communication systems. These modules are ideally suitable f or long reach
and intermediat e r each of 622Mb/s and 2.5Gb/s tr ansmission applications.
A laser diode is mounted int o a coaxial pack age integr at ed with an InGaAs monitor PD and a sing le
mode f iber pigtail.
Especially SLT4460 Series have a single stag e isolator integr ated inside.

8. Precaution
(1) Radiation emitted by laser devices can be dangerous to the eyes. Avoid eye or skin exposure to
direct or scat t ered radiation.
(2) The governmental approval is required to export t his product to other countries. To dispose of this
product, t he appropriate procedure should be t aken to prevent illeg al export at ion.
(3) The modules should be handled in the same m anner as or dinar y semiconductor devices to
prevent the electro-static damag es. For safe keeping and carrying, the m odules should be
packag ed with ESD proof material. To assemble the modules on PCB, the workbench, the
soldering ir on and t he hum an body should be g r ounded.
(4) The stress to the fiber pig tail may cause the damage on the perform ance. The fiber pigtail may
snap off by dropping the module.
(5) Please pay special attention to the atm osphere condition because the dew on the module may
cause some electrical dam ages.
(6) Under such a strong vibrat ion environment as in automobile, the perform ance and r eliability are
not guar ant eed.
