摘　　要：电信局内设备连接的增长使人们迫切需要开发低成本的甚短距离(VSR)光传输技术。传统的40Gb/s(STM-256/OC-768)接口是为长距离传输设计的,对于传输距离在300m以内的大容量、高速传输场合并不适用,因此有必要寻找一种比现有40Gb/s短距离方案成本低的替代方案。详细介绍了VSR5-1.0协议。Duc to the increased intra-oftice interconnections, it is desired to develop a kind of cost-effective very short reach （VSR） optical transmission technology, The traditional 40Gb/s （STM-256/OC-768） optical interfaces are designed for long distance systems, they are not suitable for high speed, high capacity and short distance （〈300m） applications. Therefore, it is necessary to find a less costly one to replace the current 40Gb/s short reach technologies. At present, among all of the short reach technologies, VSR5-1.0 IA is the better one, In this paper, a brief introduction to this implementation agreement is presented.
