摘要：
A new class of multilength, constant-weight two-dimensional multiwavelength optical orthogonal code (2D MWOOCs) with large capacity and good correlation properties is constructed based on multilength one-dimensional (1D) OOCs. The performance of these new MWOOCs in an optical code division multiple access (OCDMA) network with double-services is analyzed. The result shows that media with the shorter codewords performs much better than the media with longer codeword, and OCDMA system with these new multilength MWOOCs performs well. These features allow large capacity multimedia transmission in OCDMA system.
