ABSTRACT:
A system and methods are provided for communicating optical signals in a multipath optical network, such as ring network architecture. The system and methods provided are operable to bypass a faulty node in the optical network under various conditions. Faulty nodes may be associated with various failures, such as equipment failure, power failure, etc. The system and methods utilize an apparatus for communicating optical signals to adjacent nodes, bypassing the failed node, when a certain amount of power is provided to the node or apparatus. The system and methods utilize an apparatus for communicating optical signals to equipment located at an associated node when an amount of power is not provided to the node or apparatus.
