DWDM Transmission with LEAF and RDF Structure in 40 Gb/s Single MZM with RZ-DPSK Modulation

摘要

We propose the experiment transport of 48 Chs 40 Gb/s dense wavelength division multiplexing (DWDM) system that uses larger effective area fiber (LEAF) in combination with reverse dispersion fiber (RDF), which is a dispersion compensation device, in C band (1,530-1,560 nm) and L band (1,570-1,610 nm) wavelength range to solve the dispersion program. The single Mach-Zehnder modulation (MZM) format with erbium-doped fiber amplifier (EDFA) configuration to generate return-to-zero differential phase-shift keying (RZ-DPSK) modulation signal can compensate dispersion impairment in 48 x 40 Gb/s DWDM system. The proposed 48 x 40 Gb/s DWDM system successfully employs single MZM RZ-DPSK modulation format to reduce modulation complex configuration with EDFA to promote the power signal and using LEAF and RDF in 28 spans over 3,360 km ultra-long-haul fiber transmission successfully.
