What is a network cable? What is UTP and SFTP? and the difference between them
Network cables are designed and produced by different companies to transmit information. Over time, in order to increase the quality and speed of information transmission, newer cables are produced. Newer cables have a better design and the amount of noise and destructive signals in them is less. Two models of UTP and SFTP cables are used to transfer information, and the structure of both these cables consists of 8 wires twisted together. But the difference between UTP and SFTP network cable is related to the protective layer or the shield. In the SFTP cable, there is a shield to reduce noise and additional signals.
What is a network cable?
A network cable is a set of copper or glass wires that are used to transmit information between computers, routers, and switches. Network cable, also known as LAN cable, consists of 4 pairs of twisted wires. The reason for this structure, which is radiated to the even mode, is to reduce additional noises.
What is a UTP network cable?
The term UTP stands for Unshielded Twisted Pair, which means unshielded twisted pair network cable. Due to its low price, this cable is one of the best-selling types of network cables in the world. This cable is suitable for use in home and local networks because the volume of the network and cables is not too large and the effect of electromagnetic and radio noise on it is low. Another benefit of this cable, which has made it more popular, is its easy installation and convenient socketing. The fact that this network cable model does not have a shield makes it look slimmer and makes the cable more flexible. Also, UTP cable does not need a grounding wire.
What is a SFTP network cable?
Unshielded twisted pair wires are known as Ethernet cables, but a special type of copper cable that has high resistance to electromagnetic interference and high noise is known as SFTP network cable. SFTP stands for Screened Fully Shielded Twisted Pair. This category of network cables has a metal sheath that protects the signals transmitted through the cable from disturbing noises, thus increasing the quality of data transmission. This cable is used to transmit information over long distances. In this type of cable, twisted pairs of wires wrapped in foil have an insulating outer covering. This copper insulation is net-like and is incorporated to protect the twisted foil cables.
What is the difference between UTP and SFTP network cables?
In general, the structure of UTP cable, i.e. network cable without shield, consists of 4 pairs of wires, which do not have any protective layer of foil and shield. So that the layers of this type of cable, either individually or in general, are not protected by any coating. But shielded cable or SFTP m network cable is covered by foil and shield in addition to its protective jacket. Another difference between UTP and SFTP network cable is their price. Because these protective layers make the shielded cable more expensive.
