Abstract：
 The invention discloses a DS-OCDMA system coding and decoding sampling optical fiber grating and its producing method, it belongs to coding and decoding technology field of optical CDMA communication, the character is: modulating average optical fiber grating using new sampling structure, making its -1 grade reflection peak of reflected spectrum have the needed coding and decoding function. It only needs to average phasic moulding board, compared to current method, it decreases producing needed precision, and increases producing flexibility, so the producing cost is reduced, and it is suitable to be produced in great force.
