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.

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.
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.
