LSCX110
Description
LSCX110 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.
•Alternative Package Styles: LSC2110 - 14 Pin DIL LSC4110 - 14 Pin“Butterfly”
Applications
•Telecommunications
•Local Area and Metropolitan Area Networks
•Point-to-Point Data Communications
•Fiber Optic Sensors
•Cable Television
•Military Communications and Control Systems
•Instrumentation
LSCX110 packages include 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 base of the 14 pin “butterfly” package and a “bullhorn” type flange is used on the 14 pin DIL 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.
