980 nm Pump Laser Diode
980 nm Pump Laser Diode
Description:
The 980 nm pump laser diodes utilizes a planar construction with chip on subcarrier. The high power chip is hermetically sealed in an epoxy-free and flux-free 14-pin butterfly package and fitted with a thermistor, thermoelectric cooler, and monitor diode.
The BFLD-980F pump module uses FBG stabilization to “lock” the emission wavelength. It provides a noise-free narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications that require the highest performance in spectrum control with the highest available powers. This module complies Telcordia GR-468-CORE requirement.
Features:
- Kink-free operating power up to 600mW;
- Epoxy-free, and flux-free 14-PIN butterfly package with SM Hi1060 or PM fiber;
- Fiber Bragg grating stabilization;
- Wavelength selection available;
- Integrated thermoelectric cooler, thermistor, and monitor diode
Applications:
- Dense wavelength division multiplexing (DWDM) erbium doped fiber amplifiers (EDFA)
- Reduced pump-count EDFA architectures
- Very long distance cable television (CATV) trunks and very high node count distribution
Please refer to the data sheet for detailed specifications.
