产品描述
本以太网光猫提供1光纤接口和1个以太网接口,能够实现10/100Base-T以太网数据在光纤通道上的传输,是一种高性能、自学习式以太网桥。该设备作为以太网的延伸设备,利用现有网络,以较低的成本实现两端以太网互联。设备内置环路测试功能,为工程开通和日常维护提供便利。
功能特点
◆ 基于自主知识产权的集成电路
◆ 设备能管理到远端设备的状态, 网管数据不占用用户业务时隙
◆ 可以在本端强制让对端设备的速率跟随本端;
◆ 以太网支持超长包,最大包长度支持到2036字节(包括CRC32的4个字节)
◆ 内置动态以太网MAC地址列表(4096个),具有本地数据帧过滤功能
◆ 光以太网接口100M,全双工,支持VLAN协议;
◆ 内部有以太网数据监控自动复位功能,不会死机;
◆ 可以在本端强制让对端设备的速率跟随本端(非成帧时无效)
◆ 机架式设备网管接口采用SNMP。
◆ 设备支持非成帧模式(2048K)设置,应用灵活,并且能在非成帧时也能管理到远端设备
◆ 以太网接口10M/100M,全/半双工完全自适应,支持VLAN协议;
◆ 以太网口支持AUTO-MDIX(交叉线和直连线自适应);
◆ 能与以太网转E1-----E1光纤MODEM-----本设备 联接成三点网络
