Performance of 100 Gbit/s Transmission System Based on Non-Return to Zero and Return to Zero in Single Mode Fiber High-dispersion Fiber
Transmission performance of 100Gbit/s signal with non-return to zero (NRZ) and return to Zero (RZ) in single mode fiber (SMF) high-dispersion fiber is investigated. The bit error rate (BER) against transmission distance, laser power and chromatic dispersion is simulated and analyzed. The maximum transmission distance is obtained for different modulation format. Comparison of NRZ and RZ transmission over SMF high-dispersion fiber, it is shown clearly the advantage of NRZ modulation scheme for 100Gbit/s transmission over long SMF link. The scheme of chromatic dispersion compensation is also studied.
