Abstract
Systems and methods for monitoring an Optical Multiplex Section of a communication network are provided. A method, according to one implementation, includes the step of obtaining parameters related to optical signals traversing an Optical Multiplex Section (OMS) of a communication network. The OMS, in this example, includes multiple fiber spans defining a primary path and one or more protection paths. The method further includes the step of using the obtained parameters to determine a Signal-to-Noise Ratio (SNR) value associated with optical signals transmitted over the primary path. In response to determining that the SNR value falls below a predetermined threshold, the method includes the step of performing a switching action to enable transmission of optical signals over one of the one or more protection paths.
