Description

highly reliable fiber optic light sources operating in the 1550 nanometer band. The internal DFB lasers are based upon InGaAsP ridge waveguide technology and fabricated by the Metal Organic Vapor Phase Epitaxy (MOVPE) process, resulting in long lifetimes and modest threshold currents. The LSC2210 package includes a photodiode for monitoring the laser output, a thermistor for monitoring laser heatsink temperature, and a Peltier effect thermoelectric cooler (TEC). A heatsink mounting flange is incorporated into the industry standard 14 PIN package. 5962-9396E (11/94)

Absolute Maximum Ratings at 25°C 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.
