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.
