Virtual common space: using WDM in metro access networks

摘要

A system and method utilizing inexpensive “Coarse” WDM (CWDM) components to extend the economic utility of a service provider's local network service (LNS) feeder fiber used to serve business customers. Using these existing components and a hybrid of PON and SONET technologies, the invention provides many of the advantages of “Common Space” equipment through optical in lieu of electronic multiplexing. The technique reduces access costs, decreases provisioning time, reduces capital expenditures, and enables more aggressive marketing for local business services.
