描述 Description

LSC2500 laser modules are highly reliable fiber optic light sources operating in the 1550 nanometer band. The internal DFB lasers are based upon InGaAs ridge waveguide Multi Quantum Well technology and fabricated by the Metal Organic Vapor Phase Epitaxy (MOVPE) process, resulting in long lifetimes and modest threshold currents.

The LSC2500 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.

The LSC2500 also has 30 dB of optical isolation which is temperature controlled to maintain isolation over the full operating temperature range.
