Abstract
Optical-to-electrical and electrical-to-optical signal conversion is substantially eliminated for performance of monitoring and maintenance functions within a wavelength-division-multiplexed optical network having a Network Control Element by detecting optical intensities of signals conveyed over wavelength channels at the optical layer. Values associated with the detected optical intensities are generated and conveyed to the Network Control Element. The Network Control element analyzes these values for the purposes of fault detection, channel power monitoring, channel signal to noise ratio determinations, channel continuity checks, and network provisioning.
