FBG Wavelength Locker

FBG Wavelength Locker
       The wavelength of pump laser diode is varied at different operating temperatures. Fiber Bragg Gratings (FBG) Wavelength Locker with low reflectivity is used to stabilize the wavelength and intensity of EDFA pump laser. It can stabilize the channel wavelength to ITU-T Grid standard wavelength in DWDM systems, network monitoring and fiber sensor applications. According to the customer's locking requirements for the pump laser, single FBG or double FBG  configuration can be provided for wavelength locking.
