千兆以太网 crc

Gigabit Ethernet is a speed definition for the Ethernet protocol which can provide 1-gigabit data transmission per second. 1 Gigabit is equal to the 1,000Mbps speed. Gigabit Ethernet also refers to an ethernet port which can provide 1-gigabit speed.

千兆以太网是以太网协议的速度定义，可以每秒提供1千兆位数据传输。 1千兆比特等于1,000Mbps的速度。 千兆以太网还指可以提供1千兆位速度的以太网端口。

千兆以太网标准(Gigabit Ethernet Standard)

Gigabit Ethernet is an established standard which is mainly described IEEE 1000Base-T (802.3ab) and later TIA 1000Base-TX is created which requires CAT6 cable to work in a reliable fashion. Other relavent standards are

千兆以太网是已建立的标准，主要描述IEEE 1000Base-T(802.3ab)，后来创建了TIA 1000Base-TX，它要求CAT6电缆以可靠的方式工作。 其他相关标准是

• 1000BASE-CX is the first Gigabit Ethernet standard which works in 25 meters.
  1000BASE-CX是首个可在25米范围内工作的千兆以太网标准。
• 1000BASE-SX is a fiber cable Gigabit Ethernet standard which works up to 550 meters.
  1000BASE-SX是光纤电缆千兆位以太网标准，可工作达550米。
• 1000BASE-LX is another fiber optic cable standard which works up to 5 kilometers.
  1000BASE-LX是另一种最长可达5公里的光缆标准。
• 1000BASE-T is coaxial cable or CAT5E or CAT6 standard which works up to 100 meters.
  1000BASE-T是同轴电缆或CAT5E或CAT6标准，最长可达100米。

千兆以太网连接(端口和电缆)(Gigabit Ethernet Connection (Port and Cable))

Gigabit is a very fast connection wherein a single second 120 MB or megabyte data can be transferred theoretically. But in the real world, it may a bit lower related to the remote system speed. As a fast connection, Gigabit Ethernet port and cable should meet some requirements which are generally CAT5e or CAT6 cable or fiber cable. Even fiber cable provides less delay creating a fiber cable infrastructure that is hard and expensive. Generally, CAT6 cables are used to connect network devices like modem, switch router, firewall, computer with each other. As a connector like other ethernet connections, RJ-45 is used.

千兆位是非常快速的连接，其中理论上可以传输单个第二个120 MB或兆字节的数据。 但是在现实世界中，它与远程系统速度有关可能会更低。 作为快速连接，千兆位以太网端口和电缆应满足一些要求，通常是CAT5e或CAT6电缆或光缆。 即使是光缆，也可以减少延迟，从而创建既硬又昂贵的光缆基础结构。 通常，CAT6电缆用于将网络设备(例如调制解调器，交换机路由器，防火墙，计算机)相互连接。 与其他以太网连接一样，使用RJ-45作为连接器。

如何在Windows中列出千兆以太网(How To List Gigabit Ethernet in Windows)

In windows to get information about the Gigabit Ethernet theControl Panel -> Network and Internet -> Network Connectionssteps should be following and the following screen will list existing network connections. Generally the network connection name will containGigabitterm which refers to the Gigabit Ethernet.

在要获取有关千兆以太网的信息的窗口中，应遵循“Control Panel -> Network and Internet -> Network Connections步骤，以下屏幕将列出现有的网络连接。 通常，网络连接名称将包含Gigabit术语，该术语指的是千兆以太网。

千兆以太网与快速以太网(Gigabit Ethernet vs Fast Ethernet)

Fast Ethernet is another ethernet connection type or speed which is one level lower than Gigabit ethernet. Gigabit ethernet provides 1 Gbps or 1.000 Mbps speed where Fast Ethernet is 100Mbps . This means Gigabit ethernet has 10 times more bandwidth then fast ethernet. Also fast ethernet can work with CAT5 but gigabit can only work with CAT5E.

快速以太网是另一种以太网连接类型或速度，比千兆以太网低一个级别。 千兆以太网提供1 Gbps或1.000 Mbps的速度，而快速以太网为100Mbps。 这意味着千兆以太网的带宽是快速以太网的10倍。 快速以太网也可以与CAT5一起使用，但千兆位只能与CAT5E一起使用。
