980nm Pump Laser Module Grating Stabilized, 300mW
LC94
These lasers are designed as pump sources for
Erbium-Doped 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. Devices are available with kink free output
powers to 300mW. The LC94 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.
Features:
• Double Fiber Bragg Grating wavelength stabilization
• High output power, up to 300mW kink free
• Single-mode fiber pigtail
• 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
