Two. Introduction of more than five kinds of 8-core shielded twisted pair
Twisted pair (twisted? Pair) is a transmission medium composed of one or more pairs of insulated wires wound together according to certain specifications (generally counterclockwise), and belongs to the transmission medium of information communication network. Twisted pair used to be mainly used to transmit analog signals, but now it is also suitable for transmitting digital signals. It is a common wiring material.
There are three kinds of twisted pairs, five kinds of wires and over five kinds of wires, and the latest six kinds of wires. The former has a thin line diameter, while the latter has a thick line diameter.
Super-class 5 has the advantages of small attenuation and crosstalk, higher attenuation-crosstalk ratio (ACR) and signal-to-noise ratio (SNR), smaller delay difference and greatly improved performance. Category 5 cables are mainly used for Gigabit Ethernet (1000Mbps).
Third, the manufacturer recommended
1, Shenzhen Chuangjie Technology Co., Ltd. (hereinafter referred to as "Chuangjie Technology"), established on 20 12, is a high-tech enterprise engaged in network products.

Since its establishment, the company has adhered to the strategic policy of survival by quality and development by reputation, and has made outstanding achievements in the fields of information network, telecommunications, security monitoring, multimedia and other integrated wiring cables. In 2005, it passed the CCC certification of national compulsory products and was awarded the "Quality Inspection Report" by the State Quality Supervision Bureau.
Although the prices of the above-mentioned super-five types of 8-core shielded twisted pair are quite different, they are mainly caused by the differences of brands and pricing units, so consumers had better identify each piece of information before making a decision. In addition, the difference between super five kinds of 8-core shielded twisted pair and multi-core soft conductor is illustrated by examples. We know that the difference between the two is reflected in the use, performance and advantages. Twisted pair has a higher attenuation crosstalk ratio, so it is more suitable for Gigabit Ethernet (1000Mbps).
