980nm pump butterfly laser module for EDFA
980nm pump module utilizes a planar construction with chip on subcarrier. The high power chip is hermetically sealed in a epoxy-freeand flux-free 14-pin butterfly package and fitted with a thermistor, thermoelectriccooler, and monitor diode.
980nm 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 described in Telcordia GR-468-CORE requirement.
Features:
Kink-free operating power up to 400mW;
epoxy-free, and flux-free 14-PIN butterflypackagewith SM Hi1060 or PM fiber;
Fiber Bragg grating stabilization,Wavelength selection available;
Integrated thermoelectric cooler, thermistor, and monitor diode.
Application:
Next generation dense wavelength division multiplexing(DWDM) erbium doped fiberamplifiers(EDFA);
Reduced pump-count EDFA architectures;
Very long distance cable television(CATV) trunks and very high node count distribution.
