【Abstract】 The code applied to the FBG encoder/decoder is designed. The principle and method of grating array design are given. A point-to-point system of asynchronous OCDMA based on FBG encoder/decoder is proposed, and the experiment has been successfully demonstrated. The data rate and address codes of the encoder/decoder can be tuned independently with the introduction of the trape ziform struture of fiber delay-line and piezoelectric ceramic.更多还原
