At first glance, all cables look the same. It is even possible that there are cases where the user finds network cables of different colors, but this is a purely aesthetic factor.
To know how to differentiate between Ethernet cable types, look at the inscription printed on the plastic cover of the cable or the packaging. Not only the category but also the type of shielding is always indicated in gray letters.
What Is The Frequency Of An Ethernet Cable?
As we have already explained, each type of Ethernet cable is associated with a data transmission and download speed, and also a frequency,
In this case, the frequency indicates the power of the network. But keep in mind that the longer the cable, the greater the data loss. Usually, the peak speed obtained will be higher in one-meter cables than in five-meter cables. Therefore, if a very long cable is required, it would be more interesting to opt for higher categories.
Types Of Shields
When looking at the cable category on the plastic sheath, three or four letters will also be seen. These refer to the electromagnetic shielding of the copper wires that make up the factory assembly line of cable, protecting these wires. For domestic use, it is not necessary to have such shielding.
UTP (Unshielded Twisted Pair): it is an unshielded cable, widely used in domestic environments and not recommended in cases of very long cables that go inside the wall.
FTP (Foiled Twisted Pair): the cable pairs are twisted and are also unshielded but have global protection that protects them all at once. They are also recommended for home use.
STP (Shielded Twisted Pair): each pair of twisted cables is individually covered by a conductive mesh, which acts as a shield. They are recommended for installations that go between walls.
SFTP (Shield Foiled Twisted Pair): in installations between walls of extended length, these cables are usually used, more expensive, and more protected. An individual protective mesh shields the twisted pairs of cables and has global coverage for all cables.
