Dual Stage Optical Label Switch using out-of-band wavelength and code optical properties

A method of generating circuits in an optical network is Optical Multiple Protocol Lamda Switching (OMP?S). For OMPλS, the wavelength of the optical carrier is used as an out-of-band label to route data through the network without requiring periodic conversion to the electrical state. Presented is a method of adding a second dimension of optical encoding, as an out-of-band label, to be used for routing data through a label-switched network. Combining wavelength and code multiplexing techniques generates an O³ circuit-switched network with a data capacity of up to 5.7 Tb/s on each point-to-point link in the network. The proposed architecture uses two stages to process and map labels for each bit transmitted through the network. The architecture for the Dual Stage Optical Label Switch (DSOLS) is presented.
