Is it dangerous to choose a LAN cable and look only at "CAT ○"?

If you have a network (LAN) at home, you should use a LAN cable (Ethernet cable) with a considerable probability.Basically, the communication is Wi-Fi, but there are many cases where LAN cables are used only for short sections such as routers and Wi-Fi access points, Wi-Fi slave unit and TV / video recorder.What kind of standard do you choose for LAN cables?What kind of standard do you choose such a LAN cable?The connector is 8-pole 8 core / modular "RJ-45", of course, length, color, and price...That alone is not enough.It is essential to choose from the category according to the maximum communication speed of the network device.Roughly speaking, it is OK if you choose a large category (cat) number, but category 6 or more (cat 6/6e/7) requires attention.There are two types of LAN cables with category 6A or higher, "UTP" and "STP", and you may be involved in troubles that you can unexpectedly choose STP.In the LAN cable, UTP is not shielded (processing to block external noise), STP refers to a shielded pair twist cable.If you judge it only here, you will want to choose a STP with high noise resistance, but the STP cable requires ground processing (both ends in parallel).If you do not do the right ground processing, you will be affected by noise, which is counterproductive.In addition, the ground used in the 3 -pinkon sensor of ordinary households is a security ground for the purpose of preventing electric leakage / electric shock, and is similar to the ground for functioning to ensure stable operation of electrical equipment.If you want a new LAN cable, choose a category 6 or 6A UTP cable that doesn't need to be considered.
