cat5和cat5e的区别

CAT5 or Category 5 is a copper cable used in computer networks and cable TV. It is popularly used in Computer Network start Ethernet which is very popular in LAN computer networks. Cable standards like CAT5 are defined by the Electronic Industries Association and Telecommunications Industry Association simple EIA\TIA. The naming of the CAT5 comes from Category 5 because it is the 5th generation cable standard which is superior to previous generations and versions like CAT3, CAT4, etc.

CAT5或5类是用于计算机网络和有线电视的铜质电缆。 它广泛用于计算机网络启动以太网，这在LAN计算机网络中非常流行。 像CAT5这样的电缆标准由电子工业协会和电信工业协会(简称EIA \ TIA)定义。 CAT5的命名来自第5类，因为它是第5代电缆标准，优于以前的版本和CAT3，CAT4等版本。

CAT5 cables contain four copper pairs to transmit signals. Fast Ethernet is an Ethernet standard which is designed to provide 100 Mbps network speed in 100 meters. But the Fast Ethernet standard only uses two copper wire and other two copper wire is not used theoretically. In order to use free two copper wires and provides Gigabit Ethernet standard named CAT5e is created.

CAT5电缆包含四对铜缆以传输信号。 快速以太网是一种以太网标准，旨在在100米内提供100 Mbps的网络速度。 但是快速以太网标准仅使用两根铜线，而理论上不使用其他两根铜线。 为了免费使用两条铜线并提供千兆以太网标准，创建了CAT5e。

CAT5 cables can provide network speeds up to 1Gbps with the enhanced CAT5e standard cables. But in common CAT5 cable is designed to support Fast Ethernet or 100 Mbps transfer rates. 1Gbps can be calculated as 120 MBps or 120 Megabyte per second. On the other hand, 100 Mbps can be calculated as 12 MBps or 12 Megabyte per second theoretically.

CAT5电缆可使用增强型CAT5e标准电缆提供高达1Gbps的网络速度。 但是通常，CAT5电缆旨在支持快速以太网或100 Mbps传输速率。 1Gbps可以计算为每秒120 MBps或120 MB。 另一方面，理论上100 Mbps可以计算为每秒12 MBps或12 MB。

Ethernet cables designed to work maximum at 100 meters range. CAT5 cable also provides the same range where the range is designed to 90 meters between the patch panel and wall jack and 10 meters between each jack and the attached device. Actually, longer ranges than 100 meters can work but it is not guaranteed to work properly.  100 meters range limit is designed to work properly but you can try a bit longer distances if you do not need a high level of reliability.

以太网电缆的最大工作距离为100米。 CAT5电缆也提供相同的范围，该范围设计为配线架和墙壁插座之间的距离为90米，每个插座和所连接的设备之间的距离为10米。 实际上，超过100米的射程可以使用，但不能保证其正常工作。 100米范围限制旨在正常工作，但是如果您不需要很高的可靠性，则可以尝试更长的距离。

CAT5 cable has mainly two main types. These two types are named as solid and stranded.

CAT5电缆主要有两种主要类型。 这两种类型分别命名为solid和stranded 。

Alternatively, CAT5 has a subversion named CAT5e which is explained below in detail.

替代地，CAT5具有名为CAT5e的子版本，下面将对其进行详细说明。

In order to connect CAT5 cables to the end and intermediate devices like computer, laptop, server, patch panel, switch, router, etc. we need connectors. Connectors are used to end a CAT5 cable two ends. CAT5 cable generally used in computer networks where RJ45 is a very popular type of connector used with CAT5 cables.

为了将CAT5电缆连接到终端设备和中间设备，例如计算机，笔记本电脑，服务器，配线架，交换机，路由器等，我们需要连接器。 连接器用于将CAT5电缆的两端端接。 CAT5电缆通常用于计算机网络，其中RJ45是与CAT5电缆一起使用的非常流行的连接器类型。

CAT5e is updated standard for the CAT5. e in CAT5e stands for enhanced where some usage and capability of the cable is enhanced without a major change. CAT5e is designed to support Gigabit Ethernet speed which is 1 Gbps for the same range which is 100 meters. In standard CAT5 there are 4 copper lines where only 2 of them is used. With CAT5e the 2 free copper lines also used to increase the bandwidth and performance of the cable. Because of the CAT5e uses more copper lines which means more signal in the same lines the tests of the CAT5e is stricter then CAT5 cables.

CAT5e是CAT5的更新标准。 CAT5e中的e表示已增强，其中电缆的某些用法和功能得到了增强，而无需进行重大更改。 CAT5e设计为在100米的相同范围内支持1 Gbps的千兆以太网速度。 在标准CAT5中，有4条铜线，其中仅使用2条。 使用CAT5e时，两条自由的铜线还用于增加电缆的带宽和性能。 由于CAT5e使用更多的铜线，这意味着在同一根线中会有更多的信号，因此与CAT5电缆相比，CAT5e的测试更加严格。

CAT5 is used for a lot of different installations but after some time with the advance of the computer networks and equipment, it became insufficient. CAT6 is designed to be superior to CAT5 in speed, range, consistency, etc. Here we will compare both cabling standards CAT5 vs CAT6 in general.

CAT5用于许多不同的安装，但是随着计算机网络和设备的发展，一段时间后，CAT5变得不够用。 CAT6在速度，范围，一致性等方面均优于CAT5。在这里，我们将比较两种电缆标准CAT5和CAT6。

Both CAT5 and CAT6 provides excellent backward compatibility with older cable standards to work together

CAT5和CAT6均提供与旧电缆标准的出色的向后兼容性，从而可以一起工作
