980 nm Pump Laser
Module Unstabilised
100-220 mW
Features
These lasers are designed as pump sources for ErbiumDoped Fibre Amplifier (EDFA) applications. Proprietary
processes and techniques of coupling the fibre to the laser
allow high output powers which are very stable with both
time and temperature. Devices are available with kink free
output powers from 100 mW to 220 mW.
• Hermetically sealed 14-pin
butterfly package.
• Wavelength 975-985 nm
• Output power up to 220 mW
• Single mode fibre pigtail
• Internal thermoelectric heatpump
and monitor photodiode.
• Telcordia GR-468-CORE
compliant.
• Field proven high reliability.
Applications
• Low noise, high power EDFA
