发送器应符合表39-2中的规范。 对于所有链路,输出驱动器应通过发送网络transmission network与跨接电缆组件jumper cable assembly交流耦合,并在跨接电缆组件jumper cable assembly(TP2)的输入端测量输出电平,当如图39-2所示端接时,满足图39-3和图39-4的眼图要求。图39-3和图39-4中的符号X1和X2在表39-3中定义。
10BASE-5也被称为Thick Ethernet or Thicknet,是以太网的第一个商用变体; 使用直径10mm的50欧姆粗同轴电缆(Coaxial Cable),总线拓扑结构,站点网卡的接口为DB-15连接器,每个网段允许有100个站点,每个网段最大允许距离为500m,网络直径为2500m,可由5个500m长的网段和4个中继器组成; 利用基带的10M传输速率,采用曼...
数字/T/F/C等:最后一个如果是数字,则表示单段网线的最大长度(基准单位是100m);如果是字母,则依次解释如下:T代表承载信号的物理介质是双绞线缆(Twisted Pair Cable,又分为UTP(Unshielded Twisted Pair,非屏蔽双绞线)和STP(Shielded Twicted Pair,屏蔽双绞线)两种),在这里每一对传送信号的双绞线互相缠绕以减少电...

1000BaseCX Short haul copper “twin ax” STP (Shielded Twisted-pair) cable. The MAC (Medium Access Control) Layer The MAC layer of Gigabit Ethernet uses the same CSMA/CD protocol as Ethernet. The maximum length of a cable segment used to connect stations is limited by the CSMA/ CD protoco...
用户可以采用这种技术在原有的快速以太网系统中实现从100Mbps到1000Mbps的平滑升级。 与 1000Base-LX、1000Base-SX和1000Base-CX网络介质不同,1000Base-T不支持8B/10B编码/译码方案, 需要采用专门的更加先进的编码/译码机制。 如图所示,1000Base-T是千兆以太网4个物理层之一,收发机制为千兆以太网的两个标准之一: IEEE...
There are five physical layer standards for Gigabit Ethernet using optical fiber (1000BASE-X), twisted pair cable (1000BASE-T), or shielded balanced copper cable (1000BASE-CX). 1000BASE-LX and 1000BASE-SX SFP are two common types of optical transceiver modules in the market. Today’s topic ...
