Tb/s单信道正交ASK/DQPSK光标记交换系统设计

The design of single-channel Tb/s orthogonal ASK/DQPSK optical label switching system

随着光信道传输速率要求的不断增长,光标记交换(OLS)技术已成为目前光传输网中最具研究潜力的光交换技术,现阶段光标记交换系统中的单信道传输速率都在Gb/s量级上。为此,提出将正交调制光标记交换系统与光时分复用(OTDM)系统相结合,实现了一种Tb/s单信道的正交ASK/DQPSK光标记交换系统,并对系统进行了仿真实验,验证了系统的可行性。

With the growing demand of optical channel transmission rate, optical label switching （OLS） technology has become the most potential research in the optical transmission network. At present the single channel transmission rate of light label switching system is Gbit/s magnitude. This paper propose a process that combine the quadrature light label switching system and optical time division multiplexing （OTDM） system, realize a single-channel Tbit/s orthogonal ASK/DQPSK optical label switching system and carry out the simulation experiments and verify the feasibility of the system.
