摘要
光时分复用(Optical Time Division Multiplexing, OTDM)是提高光通信传输速率的有效方法之一[1]。光通信研究人员利用光学方法将电时分复用信号转换成更高速率的光信号。OTDM系统克服了电子通信速率的限制[7]。本文利用OptiSystem软件仿真设计了一个点对点40Gbps OTDM系统，并在系统中采用DPSK(差分相移键控)调制格式。实现了高效、可靠的数据传输，满足了高速光纤通信对带宽日益增长的需求。
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.
