Demonstration of Ultra-low-cost Wavelength Labelling System Supporting Bidirectional 240-lanes-DWDM Optical Networks

A novel design of a bidirectional 240-lanes-DWDM wavelength labelling system is demonstrated. The simultaneous process of 240-lanes wavelength labelling signals includes demodulation, forward error correction and optical power monitoring occupies less than 70% of total logic resources on Xilinx XC7A200T. The monitoring error is less than 0.5dB when the service optical power is in the range of -23 ~ -13 dBm.
