BOOKHAM LC95B74-20R 980nm pump laser module - grating stabilized, 400mw Datasheet

Data Sheet
980nm Pump Laser Module Grating Stabilized, 400mW
LC95
These lasers are designed as pump sources for ErbiumDoped Fiber Amplifier (EDFA) applications. Processes and
techniques of coupling the fiber to the laser allow high output
powers that are very stable with both time and temperature.
The grating is located in the pigtail to stabilize the wavelength.
Features:
• Double Fiber Bragg Grating wavelength stabilization
• High output power, up to 400mW kink free
Devices are available with kink free output powers to 400mW.
• Single-mode fiber pigtail
The LC95 series pump module utilises a double Fiber Bragg
Grating design for enhanced wavelength and power stability
performance. This product has been designed to ensure
superior wavelength locking over drive current, temperature
and optical feedback changes.
• Internal thermoelectric heatpump and
monitor photodiode
• Hermetically sealed 14-pin butterfly package
• Telcordia GR-468-CORE compliant
• Field proven high reliability
• RoHS compliant
Applications:
• Low noise EDFAs
• Dense wavelength division multiplexing
(DWDM) EDFAs
• CATV Applications
