ABSTRACT:
Systems, networks, and methods of providing an Internet protocol routing network are disclosed. One Internet protocol routing network includes: 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/decoder coupled to the optical fiber cable, where a number of channels associated with the local subnet routers are assigned an OCDMA signature code.
