【摘要】 甚短距离传输 (VSR)是一种用于短距离 (约 30 0 m)内进行 STM- 6 4帧数据的光传输系统。它比一般的 10 Gbps光传输系统成本低 ,主要应用于交换机、核心路由器 (CR)、分插复用器 (ADM)和波分复用(WDM)终端等网络中不同层次设备之间的互连。本文介绍了 VSR的 4种标准 ,分析了各自的优缺点 ,并对 VSR的应用做了讨论。更多还原

【Abstract】 Very short reach (VSR) is an optical communication system to transmit STM-64 data over a short distance (about 300 m).It has lower cost than the common 10 Gbps system.It is mainly used to link two equipments of different network layers,such as switchs,CRs,ADMs and WDM terminals.The paper introduced four specs of VSR,analyzed their advantage and disadvantage and discussed the applications of VSR.更多还原
