A high speed healing ring having a plurality of nodes is provided. The high speed healing ring includes a first link that is capable of carrying a first data in a first optical signal, which has a first wavelength, from a first node to a second node. The ring network also has a second link that is capable of carrying the first data in a second optical signal, which also has the first wavelength, from the first node to the second node. At least one of said first and second optical signals passes through at least one other node between the first node and the second node. By providing redundancy in the ring network through physical layer interface using optical add-drop multiplexers (OADMs), cost of the system may be reduced while providing a faster response time, as compared to systems based on Synchronous Optical NETwork (SONET) or Resilient Packet Ring (RPR).
