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.
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.
