Cat5: A Little Older, A Little Slower

Category 5 cabling, also known as Cat5, is an older type of network cabling. Cat5 cables were made to support theoretical speeds of 10Mbps and 100Mbps. You may be able to get gigabit speeds on a Cat5 cable, particularly if the cable is shorter, but it isn't always guaranteed.

Since Cat5 is an older type of cabling, you probably won't see them very much in the store, but you may have gotten some with an older router, switch or other networking device.

Cat5e: Faster with Less Interference

Category 5 enhanced cabling, also known as Cat5e, is an improvement on Cat5 cabling. It was made to support 1000 Mbps "gigabit" speeds, so in theory, it's faster than Cat5. It it also cuts down on crosstalk, the interference you can sometimes get between wires inside the cable. Both of these improvements mean you're more likely to get fast, reliable speed out of Cat5e cabling compared to Cat5.

Cat6: Even Faster, But Not Super Necessary

Category 6 cabling is the next step up from Cat5e and includes a few more improvements. It has even stricter specifications when it comes to interference, and its capable of 10-Gigabit speeds in some cases. You probably won't use these speeds in your home, and the extra interference improvements won't make a huge difference in regular usage, so you don't exactly need to rush out and upgrade to Cat6. But, if you're buying a new cable, you might as well, since it is an improvement over its predecessor.

之前看过测试,在局域网里,万兆网卡和万兆网关之间,CAT5E可以跑到800MB/S左右速度,可以理解为大约8G网速, CAT6可以跑满万兆也就是10G.

这个数据应该比较接近CAT5E的极限能力

肯定快，感觉得到。我用CAT 6A。

也就是说如果要申请1000/500的光纤，最好用CAT 6的线了？

问题是Chrous的ont box支持cat 6的线吗？ ...

你看错了, 等网速上10G了, CAT5E才会是瓶颈, 1G的光纤根本没有区别

直接CAT6吧。家里用的话也不会太多，价钱差不了多少。

just google it, you will find the answer on the Internet.

没区别，ONT最高支持到1GBpbs而已，cat5e刚好满足。

全 WiFi，走 5GHz，不用打洞，不用买线做水晶头

以后的各种设备，越来越多支持 WiFi

spark的猫 5g就是个摆设，只有离猫近才能收到信号，远一点到卧室，直接回到普通wifi。渣的不行了。

的确是这样。要信号好速度快还是换router或加AP吧
