The project can permit multiplex digital signals transmit in single fiber using CWDM (CoarseWavelengthDivisionMultiplexing), and realize communication between the underwater robot and the bank.
A new scheme for optimization of coarsewavelength-division-multiplexing (CWDM) system based on directly modulated lasers (DMLs) and non-zero dispersion shifted fibers (NZDSF) is proposed.
