Cooled Butterfly 980nm Pump Laser Module

Transcription

1 Cooled Butterfly 980nm Pump Laser Module Features: High output power, up to 600mW kink free Polarization maintaining fiber pigtail Fiber Bragg grating stabilization for wavelength locking over the entire operating conditions Internal thermoelectric heatpump and monitor photodiode 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. The LC96 P series pump module utilizes a 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. Devices are available with kink free output powers to 600mW. 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
