Description

LSC2110-622 laser modules are highly reliable fiber optic light sources operating in the 1300 nanometer band. The internal semiconductor lasers are based upon InGaAsP buried hetero- structure (BH) technology and fabricated by the Metal Organic Vapor Phase Epitaxy (MOVPE) process, resulting in long lifetimes and modest threshold currents. LSC2110-622 package includes a photodiode for monitoring the laser output, a thermistor for monitoring the laser submodule temperature and a Peltier effect thermoelectric cooler (TEC). A heatsink mounting flange is incorporated into the industry standard 14 pin package. The LSC2110-622 has been specifically designed to meet the requirements of STM4.1 and SONET OC12 LR1 applications. 5962-9398E (1/95)

Absolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided 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. Limits Parameter Symbol Conditions Min. Max.
