Patent ID: 7437073

Claim:
A system for providing dynamic service using optical sub-carrier multiplexing type multi-channel access, comprising: a plurality of optical sub-carrier multiplexing modems each allocated with an optical sub-carrier channel which changes dynamically to transmit user traffic through the optical sub-carrier channel and comprising a Channel Aggregation Control (CAC) unit and a Channel Aggregation Control Protocol (CACP) unit for performing initialization of the optical sub-carrier multiplexing modems and dynamic bandwidth allocation; an optical gigabit-Ethernet switch connected to an access network upstream and to the optical sub-carrier multiplexing modems downstream to monitor traffic states of the optical sub-carrier channel according to a plurality of wavelengths and a plurality of optical sub-carrier channels in order to allocate an optical sub-carrier channel dynamically; and a plurality of wavelength division multiplexing couplers for connecting the plurality of optical sub-carrier multiplexing modems with the optical gigabit-Ethernet switch, performing aggregation and branching of a certain wavelength and transmitting it.
