Abstract:Hybrid FRA consisting of general fiber G652 and dispersion compensation fiber DCF includes DCF +G652, G652 +DCF and G652+DCF +G652. The operation principle is discussed. The optimum design of hybrid FRA has been done by using optimum design software of FRA OptiAmplifier 4.0. The best structure is G652 +DCF. It can compensate dispersion and widen operation wavelength range of optical fiber network. Using Raman laser (1427 nm) as an exciting source, Raman gain spectrum and small signal amplification spectrum of optical fiber are measured by optical spectrum analyzer Q8384. The hybrid FRA has gain bandwidths of 88 nm in S and C band. It will increase the transmission channels of fiber communication network.
Keywords:Fiber Raman amplifier  Dispersion compensation  Hybrid FRA  Gain  Gain bandwidth
