Description
LSC2210 laser modules are
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.
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.

Hewlett-Packard can offer a ruggedized fiber pigtail for this product range if extreme mechanical strength is required. The pigtail length can be
customized to your specific length, with a connector, to a tolerance of ±25 mm.
Note:
1. Fiber output power change for constant monitor output current.
