System and method for a resilient optical Ethernet networksupporting automatic protection switching

摘要

A system and method is provided for operating a node in an optical Ethernet network system, comprising: generating optical signals of at least one wavelength corresponding to the node; transmitting the optical signals on each of the first and second optical fiber paths; receiving optical signals of the at least one wavelength, either directly or indirectly, from the first and second optical fiber paths; and selectively choosing signals from, either directly or indirectly, either the first or second optical fiber paths depending on the optical signals received from the first or second optical fiber path.
