Abstract
Dispersion post compensated 160 Gbit/s transmission systems are optimized for a wide range of transmission fiber and DCF input powers. The simulation results for SMF, NZDSFHD, NZDSFLD fiber types and for NRZ, RZ, CSRZ and CSRZ-DPSK modulation formats are presented. CSRZ-DPSK modulation, balanced receiver (Bal-Rx) and NZDSFHD transmission fiber combination found to be superior to others, giving 880 km system reach with Q > 6. The alternating dispersion compensation is then applied and optimized for various modulation format and fiber types. This simple dispersion management technique provided significant system reach extension of 60% when CSRZ-DPSK modulation, Bal-Rx and SMF transmission fiber combination is used.
