A DPSK modulation OTDM system at 40Gbps

Abstract

Optical Time Division Multiplexing (OTDM) is one of the effective methods to improve the transmission rate of optical communications [1]. Optical communications researchers use optical method to convert electric time division-multiplexing signal into higher rate optical signal. OTDM system overcomes the limited rate of electronic communication [7]. In this paper, we simulate and design a point to point 40Gbps OTDM system by using OptiSystem, and use DPSK (Differential Phase-Shift Keying) modulation format in this system. It achieves efficient and reliable transmission of data which satisfies an ever-growing demand for bandwidth of high-speed optical fiber communications.
