产品描述
本设备可以在一个光方向(单纤或双纤)上提供4路相互独立完全隔离的线速1000M以太网通路,提供总的带宽双向4*1000M它非常适用于同时建设内网和公众信息网,并需要4个网络高度隔离的场合,也特别适用于光缆资源特别紧张同时又需要很多独立以太网通路的场合,还很适合于在不改变原有光路的情况下对DSLAM的带宽扩容。
设备基于以太网交换芯片+FPGA方案,带远端OAM帧管理功能支持Console网管/WEB网管/独立SNMP网管,也可以与4U插卡式带SNMP网管的1光4电物理隔离收发器卡互联在SNMP软件上能管理到本设备;
功能特点
◆ 基于自主知识产权的集成电路;
◆ 为网络交换机提供链路聚合通道,双向带宽达4*1000M,同一路光纤线路传输的4组GE网络业务;
◆ 每路以太有自己的独立GE接口,真正的通道隔离,保证通过同一光纤线路传输的4组网络业务完全物理隔离;
◆ 以太网电口支持速率与双工模式自协商,以太网口支持AUTO-MDIX(交叉线和直连线自适应);
◆ 设备带掉电检测功能,能检测当光信号丢失时为对端设备掉电或是光纤不通;
◆ 支持超长帧传输,对各种扩展协议数据帧完全兼容转发;
◆ 光接口支持多模双纤、单模双纤、单模单纤三种光纤传输模式,SC/ST/FC/LC接口可选,不同波长与发光功率等多种光接口配置;
◆ 丰富的工作状态指示灯,可方便、准确地了解设备接口、链路的工作状态;
◆ 可以实现远端网管功能,有4U卡片式配置,机架式设备网管接口采用SNMP;
◆ 以太接口带三级防雷保护,防雷达到GB/T17626.5(IEC61000-4-5)短路电流波8/20μs,开路峰值输出电压6KV标准
◆ 内置电源多种电源方式可选:AC220V、DC-48V/DC+24V/DC+V12等;
