AB  - In this paper, we propose a novel signal/pump double-pass Raman fiber amplifier 
      using fiber Brag gratings (FBGs). In order to compensate the dispersion slop 
      mismatch among channels in lightwave system, FBGs embedded in different positions 
      along dispersion compensated fiber are used to control the travel length of each 
      WDM signal. Gain equalization can be achieved by optimizing the reflectivity of 
      each FBG. Maximum output power variation among channels is less than +/-0.5 dB 
      after appropriate optimization. Finally, a wavelength division multiplexing (WDM) 
      system using 40-Gb/s x 8 ch non return-to-zero (NRZ) signal transmission in a 
      100-km transmission fiber is simulated to confirm the system performance. Using 
      proposed dispersion compensation method, it may lead to 2 dB improvement in Q 
      value. Such kind of RFA may find vast applications in WDM system where dispersion 
      management is a crucial issue.
