Abstract:Key technologies,such as optical signal modulation formats,dispersion compensation and optical amplification in high-speed and long-distance are researched.The simulated model is established,which uses CSRZ modulation,DCF dispersion compensation and hybrid optical amplification technologies.The channel number is eight,the speed is 40 Gb/s.The result of the simulation shows that the transmission distance of this system reaches 840 km and Q value exceeds 10,all of which meet the expected demands.
keywords: WDM CSRZ dispersion compensation
