Description
Products in the LST242X family
are compact coaxial pigtailed
DFB laser transmitters, 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-DFB laser diode
and rear facet monitor photo-
diode. 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.
Options within the LST242X
family offer pinouts and pin
rotational orientations designed
to match existing products
available on the market. We also
offer a comprehensive range of
alternative mounting flanges
including a dual in line option.
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.
Preliminary Product Disclaimer
This preliminary data sheet is provided to assist you in the evaluation of engineering samples of the product which is under development
and targeted for release during 1997. Until Hewlett-Packard releases this product for general sales, HP reserves the right to alter prices,
specifications, features, capabilities, function, manufacturing release dates, and even general availability of the product at any time.
Laser Safety Warning
This device is a Class IIIb (3b) 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.
