1. General

SLW4470-xx/RH2 Series are 1.55µm InGaAsP/InP MQW-DFB laser diode modules designed for

wireless communication systems.

These modules are ideally suitable for optical microwave transmission applications.

A laser diode is mounted into a coaxial package integrated with a single mode fiber pigtail, a double-

stage isolator (lead content is less than 1000ppm) and an InGaAs monitor PD.

8. 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.

9. 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”.
