Description

Products in the LST2X2X family are compact coaxial pigtailed 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.

LST2X2X features a high reliability SMQW laser diode and rear facet monitor photodiode. These are electrically connected to four pins in an industrystandard configuration.

Environmental performance is designed to be compatible with the requirements of Bellcore's TA-NWT-000983 document.

Options within the LST2X2X 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.
