Diodes
The DFB1xxxC522.5xx series of Multi
Quantum Well (MQW) Distributed Feedback
(DFB) lasers have been designed specifically to
satisfy the requirements of SONET CWDM
transmission. The devices feature high output
power and wide operating temperature range.
Their uncooled, hermetically sealed, coaxial fiber
pigtailed packages are a costeffective means of
providing a highspeed light source for
intermediatereach and longreach applications.

All versions of this laser are Class 1M laser products per IEC
1
/EN
2
608251:200108. Users should observe
safety precautions such as those recommended by ANSI
3
Z136.12000, ANSI Z36.21997 and IEC 60825
1:200108.
The Food and Drug Administration's Center for Devices and Radiological Health (FDA/CDRH) in the USA has decided to harmonize their
requirements with 21 CFR 1040.10 and 1040.11 with the IEC/EN 608251 and IEC/EN 60601222 standards. This process has not yet
happened and in the interim, the CDRH agency has released'Laser
Notice No.50'to
reduce the regulatory burden. This notice allows
IEC/EN classification and labeling of lasers within the USA.
:
laser is safe for all conditions of use except when passed through magnifying optics such as microscopes and telescopes. Class
1M lasers produce largediameter beams, or beams that are divergent. The MPE for a Class 1M laser cannot normally be exceeded unless
focusing or imaging optics are used to narrow the beam. If the beam is refocused, the hazard of Class 1M lasers may be increased and the
product class may be changed. A laser can be classified as Class 1M if the total output power is below (IEC/EN) class 3B but the power that
can pass through the pupil of the eye is within Class 1.
:
moderate power lasers (cw: 5500 mW, pulsed: 10 J/cm
2
or
the diffuse reflection limit, whichever is lower). In general Class
IIIB lasers will not be a fire hazard, nor are they generally capable of producing a hazardous diffuse reflection. Specific controls are
recommended.
This product does not conform to 21 CFR 1040.10 and 1040.11. Consequently, this laser module is only
intended for use as a component by manufacturers of electronic products and equipment.
Wavelength =1270 – 1610 nm
Maximum Power = 75mW
Singlemode fiber pigtail
Fiber Numerical Aperture = 0.14
Labeling is not affixed to the laser module due to size constraints; rather, labeling is placed on the outside of the shipping
box.
This product is not shipped with a power supply.

(2) Within Europe the IEC standard has been adopted as a European Normative standard known as EN 60825, and each European country
will have its own version of this standard, for example, the British Standards version known as BS EN 60825. There can be small
differences between the different countries versions of EN 60825, and these are in part caused by the process of translating the standard
into the native language of that country.
