A Wiener deconvolution approach is proposed to monitor optical power of O-OFDM superchannel network. The impacts of TOF's bandwidth and scanning steps on power estimation performance have been studied. Simulation results show that the proposed approach can accurately monitor the power of various transmission systems via low cost TOF with optimized parameters.
We propose a regularized sparse recovery (RSR) technique to monitor optical power from the broadened optical spectrum acquired by scanning a tunable optical filter (TOF). The key idea of RSR is to find a smooth but sparse signal spectrum that matches the observed data of a broadened spectrum model within a tolerable error. Experiments demonstrated that RSR can be used to monitor accurately the power...
