100-Gb/s Coherent Optical Fiber Communication with FrequencyDomain Equalization

摘要

Multi- and single-carrier (SC) coherent optical fiber communication with frequency domain equalization (FDE) is discussed with emphasis on 100-Gb/s operation. 120-Gb/s coherent optical (CO-SCFDE) system over 317-km standard single-mode fiber is demonstrated. Coherent optical orthogonal frequency-division-multiplexing (CO-OFDM) and single-carrier frequency-division-multiplexing scheme (CO-SCFDM) are theoretically and experimentally compared.
