The shielding twisted wire, as the name suggests, is for non -shielding twisted twisted lines.It is composed of two copper -conducting lines that insulated each other. Data transmission wires with the characteristics of shielding electromagnetic interference and radiation.But now that the non -shielding twisted twisted line occupies most markets, the shielding twisted line is gradually unknown.
The advantages of non -shielding twisted wire
The transmission speed of up to 150Mbps (within a range of 0.1km) is an important advantage of blocking the twisted pair, and its transmission distance can reach farther and higher quality.But its price is slightly higher than the non -shielding twisted wire, and because its shielding layer is a radiation source, the high requirements for installation have greatly increased its wiring project cost. In contrastWire.The non -shielding twisted line itself also has strong anti -interference ability, and it does not require much professional knowledge to use. It is easy to operate, which is very simple and convenient.
Features of non -shielding twisted lines
1. First of all, there is no shielding jacket, and the diameter of the double twisted wire is relatively small, so that the merchants can save more space during use.In addition, compared with the same type of products, the cost of non -shielding twisted pair is relatively low.2. The most prominent feature of the new generation of non -shielding twisted lines is that the weight is lighter than the past products, so that it is more fast and convenient during the handling and installation process.3. In addition, the characteristics of non -shielding twisted lines are also easy to bend, so that in many special areas and environments, it is easier to install and use, so that different users can use them as they want.
The difference between shielding twisted and non -shielded twisted lines
The twisted wire is divided into shieldedtwistedpair (STP) and the unknown pair (UTP).There is a metal layer between the shielding twisted wire between the twisted and outer insulation cover.The shielding layer can reduce radiation, prevent information from being eavesdropped, and prevent the entry of external electromagnetic interference, so that the shielding twisted twisted wire has a higher transmission rate than similar non -shielding twisted pair.Non -shielding (UTP) is a data transmission line, which is composed of four pairs of different colors of transmission lines, which are widely used in Ethernet and telephone lines.Non -shielded twisted wire cables were first used in Bells invention phone system in 1881.In 1900, the US telephone network was also composed of UTP and was owned by telephone companies.
What is a non -shielded twisted twisted line
Non -shielded twisted lines are a type of twisted line.In the computer field, the twisted wire consists of a non -shielding twisted twisted line (UTP) and the shielding twisted twisted line (STP).The two have their own characteristics.The appearance of non -shielding twisted lines (UTP) is wrapped in insulating rubber. It is cheap and is the most commonly used twisted line in life.In life, except for the use of the battery radiation or the use of the network cable layout with high transmission quality, it is usually used to use it or not to shield the twisted twisted lines.
Non -shielding twisted line model
There are three types of lines, five types of lines, super five lines and six categories of lines, and the six -type line is thicker.One type of line is also called Cat1. Its maximum frequency bandwidth is 750kHz, which is generally used for alarm system, or only applicable to telephone transmission. The data transmission is not used in this.The second -class line is also called CAT2: The highest frequency bandwidth is 1MHz. The most common thing in us is to use the 4Mbps specification to the token transfer protocol, but the data transmission for voice transmission and maximum transmission rate 4Mbps is also suitable.
