Abstract


According to the principle that multi-channel dispersion and dispersion slope in the optic communication system can be compensated simultaneity by using sampled NLCFBG(SNLCFBG), In the paper, we investigate the reflect spectrum and time delay of SNLCFBG by means of the numerical  simulation , and analyze the equivalence relation between two kinds SNLCFBG formula, and consider the second formula representation is advantageous. The counting method of multi-channel numbers about SNLCFBG’s is proposed using the sampled rate of the NLCFBG, and versatile formula of counting multi-channel number is pre-calculated to out-of-band multi-channel number on the main petal and the first side petal, and which can been deduced the multi-channel number on any side petal about the SNLCFBG. The value region of chirped parameter c1 and c2 of SNLCFBG are analyzed, and it is realized that the sampled rate of the NLCFBG decided the multi-channel numbers. The peak of reflected spectrum of the SNLCFBG has relation with modulation degree. Also, we investigate the relation between the sampled rate and multi-channel equilibrium.
