1. General
SLT4460-xx/RH2-xnnnx Series are 1.27µm~1.61µm InGaAsP/InP MQW-DFB laser diode modules
designed for fiber optic communication systems. These modules are ideally suitable for CWDM of
622Mb/s or 2.5Gb/s transmission applications.
A laser diode is mounted into a coaxial package integrated with an InGaAs monitor PD, a single mode
fiber pigtail and a single-stage isolator. The lead content of this isolator is less than 1000ppm.

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
On January 27, 2003, the European Parliament and the Council of the European Union issued the
directive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and
electronic equipment (RoHS).
Member States shall ensure that, from July 1, 2006, new electrical and electronic equipment put on
the market does not contain lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls
(PBB) or polybrominated diphenyl ethers (PBDE).
Applications listed in the Annex are exempted.
This product is compliant with RoHS 6/6 directive with exemptions “Lead in glass of cathode ray tubes,
electronic components and fluorescent tubes” and “Lead as an alloying element in steel containing up
to 0.35 % lead by weight, aluminium containing up to 0.4 % lead by weight and as a copper alloy
containing up to 4 % lead by weight”.
