ABSTRACT
In this paper, we proposed that using a pair of fiber gratings in a section of the transmission fiber, a gain clamped broadband distributed fiber Raman amplifiers (DRA) can easily be made based on the utilization of the pumps’ interactions and uneven gain property along the fiber in the amplifier.
