In this paper, plastic optical fiber access network based on optical code-division multiple access technique is proposed by analyzing the multiplexing technology in access network. In this optical access network, each optical network unit is equipped with a fixed optical encoder and a fixed decoder, both of which are tuned to the control channel. Each optical network unit also has a tunable optical encoder and a tunable optical decoder that can operate at any one of data channels independently. A novel protocol that can efficiently support real-time multimedia communication is presented for the encoders and decoders to coordinate message transmission. The effective solution to FTTO or FTTH is inexpensive and that gives us a new roadmap.
