Patent ID: 7983563

Claim:
An Internet protocol routing network, comprising: a number of local subnet routers, where the routers are Internet protocol (IP) enabled; a single mode optical fiber cable, where the local subnet routers are coupled to the optical fiber cable; and one or more optical code division multiple access (OCDMA) encoder/decoders coupled to the optical fiber cable, where a number of channels associated with the local subnet routers are each assigned an OCDMA signature code and an IP address and are mapped to a first group of DWDM wavelengths for downstream traffic and to a second group of DWDM wavelengths for upstream traffic where the OCDMA encoder/decoders are each initialized with a DWDM assignment according to a wavelength conversion table, and where the first group of DWDM wavelengths for downstream traffic are converted to a third DWDM wavelength group without decoding the OCDMA signature codes and the second group of DWDM wavelengths for upstream traffic are converted to a fourth DWDM wavelength group without decoding the OCDMA signature codes.
