Module
Technical Data
LSC2110-622
Features
Description
• 2.5 Milliwatt Peak Optical
Power Output
• Center Wavelength between
1294 nm and 1329 nm
• Narrow Linewidth: <1.7 nm
• Modulation Bandwidth:
>1 Ghz
• Wide Operating Temperature Range: -40°C to +85°C
• Industry Standard Hermetic
14 Pin Dual-In-Line Package
LSC2110-622 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.
Applications
LSC2110-622 package includes a
photodiode for monitoring the
laser output, a thermistor for
monitoring the laser submodule
temperature and a Peltier effect
thermoelectric cooler (TEC). A
heatsink mounting flange is
incorporated into the industry
standard 14 pin package.
• 622 Mbit/s SONET/SDH
• Local Area and Metropolitan
Area Networks
• Point-to-Point Data
Communications
• Fiber Optic Sensors
• Cable Television
• Military Communications
and Control Systems
• Instrumentation
The LSC2110-622 has been
specifically designed to meet the
requirements of STM4.1 and
SONET OC12 LR1 applications.
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.

Absolute Maximum Ratings
Absolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided
each limiting parameter is in isolation and all other parameters have values within the performance specification. It should not be assumed that
limiting values of more than one parameter can be applied to the product at the same time.
