The Development Prospects of Wavelength Division Multi Access Communication Network Technology

This paper briefly describes the extension of point to point communication link to node connected communication network and of multiplex to multiaccess technologies. After explaining how to exploit the huge potential capacity of the optical fiber in order to realize high bit rate communication, the paper describes the components used for the wavelength division multi access communication network, particularly the tunable filters and lasers as well as the multi wavelength laser array fabricated with photonic integrated circuit technique. Finally, the paper discusses the effect of fiber dispersion and non linear characteristics on the operation of multi access systems.
