About Ethernet Cable
With the continuous development of network technology, network hardware equipment is becoming more and more advanced, network speed is getting faster and faster, and the requirements for corresponding connection hardware are getting higher and higher.
One of the network connection hardware we are talking about here is the network cable. You might say, we can just use wireless, no network cable is needed. However, in modern life, wireless networks cannot always meet people's needs. In many cases, we cannot use wireless networks. For example, when wireless network interference is severe, or when wireless network signals cannot be received, we have to use wired networks.
Ethernet Cable Categories?
In the past, ordinary home and office wired networks basically used 100M downlink speed cables, but with the popularity of gigabit networks, most of the new home routers support wireless up to 1G to 2G, and wired speeds up to 1G so-called gigabit Router, then, if you want to use a wired network, you must update the old 100M network cable to a new one that supports 1000M speed.
So here we list several types of network cables on the market, so that you can compare them when buying.
Cat5 | Cat6 | Cat7 | Cat8 | ||
---|---|---|---|---|---|
Speed | 100Mbps | 1Gbps | 10Gbps | 40Ggps | |
Max Distance | 100m | 100m | 100m | 30m | |
Connector | RJ45 | RJ45 | RJ45 | RJ45 | |
Bandwidth | 100M | 250M | 600M | 2000M | |
Crosstalk | Cat6>Cat6a | Cat6>Cat6a>Cat7 | |||
TIA/EIA | Yes | Yes | No | ||
Usage | Home | Home | DataCenter | DataCenter |
How to check the type of network cable?
There is a simple way. Normally, there are printed category information on the outside of the network cable (sheath). For example, the category 6 ethernet cable will have the word like "Cat 6".
If you want to see the difference from the internal structure of the network cable, it is also relatively easy:
- Cat5 cable has 4 twisted pairs inside, no
- The enhanced version of Cat 5 (called Cat 5e) has an extra nylon cord inside than the Cat 5 cable to prevent the cable from breaking in some dark places
- There is a plastic cross frame inside the Cat 6 cable, which divides the four twisted pairs into four grids to prevent crosstalk
Cat 7 and Cat 8 network cables are a little bit more complicated, since there are not often used in common households, so here let it be omitted.
