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鈥檚
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.
Applications
鈥?Telecommunications
鈥?Fiber in the Loop
