Signal processing for fiber-optic communications

所提出的研究的目的是研究在40和160 Gb/s比特率下运行的光纤通信系统中的全光再生技术。全光再生器提高了因传输损伤而退化的信号的质量。它们有可能使网络具有增强的功能，并增加可实现的最大传输距离。对于40 Gb/s的比特率，采用传统的电时分复用（ETDM）技术将多个低比特率信号合并成一个高比特率信号。由于所需的组件无法用于ETDM，因此160 Gb/s的比特率使用了称为光时分多路复用（OTDM）的技术。OTDM信号的解复用方法将作为一个非常有趣的主题进行探讨，同时也是实现160gb /s全光再生研究的基本要求。

The objective of the proposed research is to investigate techniques for all-optical regeneration in fiber-optic communication systems operating at bit rates of 40 and 160 Gb/s. All-optical regenerators improve the quality of signals degraded by transmission impairments. They have the potential to enable networks with enhanced functionality and increase the maximum achievable transmission distance. For a bit rate of 40 Gb/s, conventional electrical time division multiplexing (ETDM) is used to combine several lower bit rate signals into a single high bit rate signal. A technique known as optical time division multiplexing (OTDM) is used for a bit rate of 160 Gb/s since the required components are not available for ETDM. Methods for the demultiplexing of OTDM signals will be explored as a topic of considerable interest itself, but also as an essential requirement for enabling the research on 160 Gb/s all-optical regeneration.
