Abstract

The evaluation, testing and deployment of a new reconfigurable digital add/drop metro DWDM system in OnFiber’s Metro Core network is described. Through the use of large-scale photonic integrated circuits to perform DWDM multiplexing and 0E0 conversion at every node, this system supports sub-wavelength digital transport, add/drop, multiplexing and fast protection. Deployment of this new technology enabled OnFiber to consolidate its network architecture by supporting transport, switching and protection of Ethernet, SONET and Wavelength services from a common platform, while also shortening service provisioning times, simplifying service planning and engineering, and reducing operational cost and complexity for managing and scaling OnFiber’s Metro Core DWDM network.
