Abstract

This paper focuses on numerical performance comparison of three typical G.655 transmission fibers in a 40×40Gb/s dense wavelength-division-multiplexing (DWDM) transmission system operating in C-band using return-to-zero differential phase-shift keying (RZ-DPSK) modulation format and hybrid Raman erbium-doped fiber amplifier (EDFA) amplification. An optimization operation over parameters, such as span input power and pre-compensation percent, is performed in the simulation. Simulation results show that the optimum choice of fiber depends on the application requirements and type of the systems and there must be some tradeoffs. Large Effective Area Fiber (LEAF) demonstrates better performance synthetically considering Q-factor, nonlinear tolerance and dispersion tolerance, and all the three G.655 fiber types take on some superiority over the conventional G.652 fiber.
