AbstractWe propose the experimental transport of 48 channels with 40 Gbit/s dense wavelength-division multiplexing (DWDM) system that uses single-mode fiber (SMF) in combination with dispersion compensation fiber (DCF) which is a dispersion compensation device, in C and L band wavelength range to solve the dispersion program. The DWDM system scheme employing single Mach–Zehnder modulation (MZM) return-to-zero differential phase-shift keying (RZ-DPSK) modulation format with hybrid Raman/EDFA (Erbium-doped fiber amplifier) configuration to improve transmission signal, and employing an optical phase conjugation (OPC) configuration in the middle line. That can compensate for dispersion impairment and improve nonlinear effects to investigate transmission distance performances.

Abstract A full duplex WDM-PON system is designed and demonstrated based on carrier reusing scheme and by employing differential quadrature phase shift keying (DQPSK) modulation in downlink and inverse return-to-zero modulation in the uplink to transmit 40 Gbps and 20Gbps data-rate respectively. Three Mach-Zehnder modulators are used sequentially to realize the 67 % carrier suppressed return to zero (CS-RZ) DQPSK modulation in the downlink transmission. Very low bit error rate values @10‒9 and clear eye-diagrams are observed over a 40 km single-mode-fiber transmission in our proposed full-duplex configuration.
