1 980 Pump LC96U P Laser Module Grating Stabilized, 750mW Features: Fiber Bragg grating wavelength stabilization High output power, up to 750mW kink free Polarization maintaining fiber pigtail Internal thermoelectricc heatpump and monitor photodiode Hermetically sealed 4 pin butterfly package Telcordia GR-468-CORE compliant Field-proven high reliability RoHS compliant Applications: Low noise EDFA Dense wavelength division multiplexing EDFA CAT Thesee 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. The LC96U P series pumpp module utilizes a fiber Braggg grating design for enhanced wavelength and power stability performance. This product has been designed to ensure superior wavelength locking over drive current, temperaturee and optical feedback changes. Devices are available with kink free output powers to 750mW.
