摘要

Here we present a chromatic dispersion compensation module (DCM) which can achieve fourth-order dispersion compensation. This module is comprised of four dispersion compensation fiber (DCF) segments and we only need to adjust their lengths to compensate manufacturing fluctuations of transmission fiber. Simulation results show that the residual dispersion (RD) in the C-band (1530-1565 nm) is less than +/- 0.4 ps/nm for 100-km G652 compensation and is only +/- 10 ps/nm for 2000-km transmission system, which indicates that the proposed DCM can support 100 Gbit/s non-return-to-zero (NRZ) transmission system without any tunable dispersion compensator (TDC).
