An optical code-division multiple access (OCDMA) over wavelength-division multiplexing (WDM) system could be one promising solution to the symmetric gigabit access network with high spectral efficiency, cost effective, good flexibility and enhanced security. A cost-effective OCDMA/WDM system using a single multi-port en/decoder at an optical line terminal (OLT) and superstructured fiber Bragg grating...
With current mature optical device technology, OCDMA now deserves revisit. In this talk, recent progress of OCDMA using ultra-long code, super-structured fiber Bragg grating en/decoder and optical thesholder for new-generation (NwGN) FTTH system will be presented.
