Coaxial Pigtailed Laser Module Technical Data LST252X - 200 µW Coaxial Laser LST282X - 1 mW Coaxial Laser LST292X - 1.6 mW Coaxial Laser LST3X21 - Dual-in-Line Package Features • Compact Coaxial Package • Strained Multi Quantum Well (SMQW) Laser Chip • Low Thresholds Current and Operating Currents • Wide Operating Temperature -40°C to +85°C • Optical Power May Be Customized up to 2 mW • Modulation Capability up to 622 Mb/s • Convenient Variety of Pinout and Mounting Flange Options 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. The device 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 Applications • • • • • • Telecommunications Fiber in the Loop Inter/Intra Office SONET/SDH Datacommunications Switches 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. 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. 520 5965-7336E (4/97) Absolute Maximum Ratings Absolute limiting (maximum) ratings mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided that each limiting parameter is in isolation and all other parameters have values within the performance specification. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time.
