| Abstract: | 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 messge transmission.The effective solution to FTTO or FTTH is inexpensive and that gives us a new roadmap. |
