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标准 (CAT5 Standard)
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速度 (CAT5 Speeds)
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。
CAT5范围 (CAT5 Range)
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。
