<p>The present invention provides a method and system for monitoring a composite optical signal in an optical network. The method includes separating the composite optical signal into a plurality of subsets, each subset including a plurality of data points, and detecting the plurality of data points. The method and system in accordance with the present invention utilizes an optical performance monitor which is able to obtain the entire spectrum in a matter of milliseconds. The preferred embodiment of the optical performance monitor utilizes a plurality of separator modules (406) to separate sets of data points of the optical signal and transfer these data points to a device for analysis. The method and system of the present invention is faster than a conventional performance monitor. Because the optical performance monitor of the present invention allows the spectrum to be obtained in fractions of a second, real-time performance monitoring is provided.</p> |
