METHOD AND APPARATUS FOR PROTECTING OPTICAL SIGNALS WITHIN A WAVELENGTH DIVISION MULTIPLEXED ENVIRONMENT

摘要

A system and method are provided for protecting optical signals within a wavelength division multiplexed (WDM) environment. The system (400) and method utilize a single "protection" wavelength translator device (400d) to protect up to N wavelengths (?1-?N). The system (400) and method utilize N+1 wavelength translator devices (440a-440c) in order to provide protected transport for N wavelengths.
