Abstract: The concepts of optical orthogonal code and two-dimensional optical orthogonal code are introduced, and their performance is analysed.The paper analyses three types of two-dimensional optical code-division multiple access communication systems:T/S OCDMA、WDM+OCDMA、MW OCDMA, and compares their performance. The design of two-dimensional optical orthogonal code fiber delay line encoder and decoder, and the scheme of the encoder based on fiber grating is presented.
