甚短距离传输(VSR)是一种用于短距离(约300m～600m)内进行数据传输的光传输技术。它主要应用于网络中的交换机、核心路由器(CR)、光交叉连接设备(OXC)、分插复用器(ADM)和波分复用(WDM)终端等不同层次设备之间的互连,具有构建方便、性能稳定和成本低等优点,是光通信技术发展的一个全新领域,逐渐成为国际通用的标准技术,成为全光网的一个重要组成部分。本文介绍了甚短距离光纤传输技术的特点、技术规范和原理结构。
Very Short Range Transmission (VSR) is an optical transmission technology used for data transmission over short distances (about 300m to 600m). It is mainly used for the interconnection between different levels of equipment such as switches, CRs, OXCs, ADMs and WDM terminals in the network, With the advantages of convenient construction, stable performance and low cost, it is a brand new field of optical communication technology and has gradually become an internationally accepted standard technology and has become an important part of All Optical Network. This article describes the characteristics, specifications, and principles of very short optical fiber transmission technology.
