产品描述
本8路百兆以太可配置VLAN型光纤收发器是以太网IEEE802.3介质转换器,能够实现8路10/100base-T 双绞线与100base-FX二种介质之间的介质转换或延伸网络传输距离。
主要用于光纤网远距离(20/40/60/80/120公里)传输,完全支持10/100M或10M、100M的传输速率,光口和电口都可以工作于10M或100M速率下的传输应用。
功能特点
◆ 设备提供1路百兆光口,8路百兆以太网电口,自动适应10/100Mbps环境,便于与不同网络的升级;
◆ 收发器具死机监控并自复位等功能 能长期工作在大流量的视频传输环境中不死机,大大减少对设备维护工作量;
◆ 收发器内置1.25MBits大容量高速率缓存,背板交换带宽为1.8G,能避免IP摄像机在雨天夜晚道路的汽车灯光反光等监控画面急速变化的环境下帧爆发导致的传输画面卡顿现象;
◆ 支持VLAN超长数据包的传输,支持最大为1600字节以上的以太网包,适用于一些巨帧网络图像传输协议;
◆ 支持全双工和半双工网络通信,带有自动协商能力 电口MDI/MDI-X自适应无需手动调整,方便现场做线;
◆ 支持 IEEE 802.3az 节能协议,低功耗,低发热,能长时间稳定工作;
◆ 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
◆ 多种电源方式可选:AC220V、DC-48V/DC+24V/ DC+12V等;
