1. General
SLT3110 Series are 1.3µm InGaAsP/InP MQW-FP laser diode modules designed for fiber optic
communication systems. These modules are ideally suitable for up to 622Mb/s transmission
applications and have low threshold current and high performance at high temperature.
A laser diode is mounted into a coaxial package integrated with an InGaAs monitor PD, a single mode
fiber pigtail.

7. 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) The stress to the fiber pigtail may cause the damage on the performance. The fiber pigtail may
snap off by dropping the module.
(4) Please pay special attention to the atmosphere condition because the dew on the module may
cause some electrical damages.
(5) Under such a strong vibration environment as in automobile, the performance and reliability are
not guaranteed.
8. RoHS Compliancy
Compliancy versus requirements contained inside the following reference document is guaranteed:
“Directive 2002/95/EC of 27 January 2003 on the restriction of the use of certain hazardous
substances in electrical and electronic equipment” from official journal of European Union (European
Parliament and of the Council). This product is compliant at RoHS-6/6 level and using only eutectic
AuSn solder for LD and PD chip attachments to components.
