To obtain the weak signal light from the high background light,a narrow bandwidth Faraday anomalous dispersion optical filter (FADOF)was studied.The theoretical model for the filter was reported.The Faraday anomalous dispersion optical filters have two working modes:two side peak transmission and center peak transmission.The former work mode can get single peak transmission of 25% with a bandwidth of about 600 MHz.The other work mode can get a spectra with a transmission rate of almost 100% and a bandwith of about 700 MHz.The experimental measurements are consistent with theoretical results.
