产品描述
本系列产品是以太网IEEE802.3介质转换器,能够实现10/100/1000base-T 双绞线与1000base-X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(20/40/60/80/100公里)传输,完全支持10/100/1000M传输速率;
设备基于以太网交换芯片+FPGA方案,带远端OAM帧管理功能,带强大的本端与远端管理功能,可以与局端带SNMP网管的卡光纤收发器相连,也可以与带独立SNMP网管的光纤收器相连。
功能特点
◆ 自动适应10/100/1000M环境,便于与不同网络的升级电口MDI/MDI-X自适应无需手动调整,方便现场做线;
◆ 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;
◆ 收发器内置大容量1Mbits高速率缓存,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10K字节以上的以太网包,适用于一些巨帧网络图像传输协议;
◆ 设备为以太网交换芯片+FPGA方案,带远端OAM管理帧功能,可以与2U插卡式带SNMP网管的1光1电收发器卡互联,SNMP软件上能管理到本设备;可以查看与设置本端与对端的设备状态与参数,并可以设置本端与对端的以太网带宽;
◆ 支持LFP (Link Fault Pass Through)的功能,当连接收发器两端的光纤和双绞线任一发生故障时,收发器即通知另一端显示故障信息 ;
◆ 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;
◆ 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/DC24V等;支持AC+DC双电源备份模式;
