Alcatel 1998 PSF 980nm pump stabilizer for terrestrial applications Description The performance of an EDFA (Erbium Doped Fiber Amplifier) can be directly affected by the characteristics of the pump laser diode. Pump laser specifications are often adversely affected by unwanted external reflections coupling back into the laser cavity, and by temperature and injection current fluctuations. The Alcatel 1998 PSF locks the emission wavelength of your 980nm pump laser and provides immunity to spectral mode hopping due to changes in temperature, drive current and optical feedback. Alcatel Optronics offers 980 pump stabilizer in singlemode or polarization maintaining fibers and in different recoating diameters. Alcatel Optronics provides a flexible product and manufacturing capability, which enables rapid design to production cycle times. Through the use of proprietary fiber, custom-grating designs to meet specific customer applications are available on request.
