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 hetero­structure (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.

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.
