Abstract

See full text

The disclosed systems and methods are for monitoring optical performance in a spatial division multiplexing (SDM) system, comprising: i) extracting, by an optical coupler, at least a portion of a plurality optical signals propagating in different communication lanes of the SDM-based optical communication system, wherein each optical signal of the plurality of optical signals is modulated with a distinguishable pilot tone (PT) signal; ii) combining, by the optical coupler, the extracted portion of the plurality of optical signals, and generate a combined optical signal; iii) extracting, by a pilot tone detector (PTD), PT signals from the combined optical signal; iv) determining, by the PTD, optical signal specific information included in the PT signals; and v) computing, by the PTD, optical power of each optical signal based on the optical signal specific information.
