Description
Products in the SMQW pigtailed
laser module family consist of
either a coaxial style, 8 pin “sugar
cube”, or an 8 pin DIL package
operating in the 1300 nm
wavelength region and coupling
light to single mode fiber. They
are designed for use in short,
medium and long distance
networks with bit rates up to
622 Mb/s.
The device features a high
reliability SMQW Fabry Perot
laser diode and rear facet monitor
photodiode. These are
electrically connected to four
pins in an industry- standard
configuration.
Environmental performance is
designed to be compatible with
the requirements of Bellcore’s
TA-NWT-000983 document.
If the specific arrangement or
performance you require is not
listed, please contact your local
representative as our highly
flexible design and manufacturing
processes allow both physical
and electro-optical customization
to meet your needs.
A reference transmitter design
board HFCT-3000 is available for
evaluating the basic performance
of the 8 pin DIL package.
Laser Safety Warning
This device is a Class IIIa (3a) Laser Product. It may emit invisible laser radiation if operated with the fiber pigtail disconnected.
To avoid possible eye damage do not look into an unconnected fiber pigtail during laser operation. Do not exceed specified operating limits.
