Category 5e unshielded twisted pair cable capable of operating two channels of isolation signals

Abstract

The invention discloses a category 5e unshielded twisted pair cable capable of operating two channels of isolation signals. The category 5e unshielded twisted pair cable comprises a polyvinyl chloride sheath, the outside of the polyvinyl chloride sheath is provided with an electromagnetic shielding device, a tearing line is arranged between the polyvinyl chloride sheath and an aluminium-magnesium braided shielding layer, a flame retardation layer is arranged between the aluminium-magnesium braided shielding layer and an aluminium foil shielding layer, a polyvinyl chloride lining layer is arranged in the aluminium foil shielding layer, a cross is arranged in the polyvinyl chloride lining layer, the upper left of the cross is provided with an A-group twisted pair, the lower left of the cross is provided with a C-group twisted pair, the A-group twisted pair is formed by a main line and a sub-line, the main line is arranged on the sub-line, the main line is formed by a polyethylene insulation sleeve and a solid copper conductor, and the solid copper conductor is arranged in the polyethylene insulation sleeve. According to the category 5e unshielded twisted pair cable, the multilayer metal layer shielding technology is employed, the influence of high electromagnetism on the operation of the category 5e unshielded twisted pair cable can be effectively prevented, and normal operation of the cable is guaranteed.

Description

technical field [0001] The invention relates to the technical field of network cable equipment, in particular to a Category 5e network cable capable of running two isolated signals. Background technique [0002] With the development of my country's comprehensive national strength, the Internet industry has developed rapidly. Now people's daily life is inseparable from the Internet. The information security of the Internet has attracted people's attention. For the information security of the Internet, many businesses The unit adopts the dual-machine dual-network operation mode in which the internal network and the external network are physically isolated. There are a large number of network connections from the access switch to the desktop computer, which has become a difficulty in the construction of the dual network. For the new network wiring, laying double line to achieve dual-network isolation, but for the transformation of the original line with only one network line, two...

[0002] With the development of my country's comprehensive national strength, the Internet industry has developed rapidly. Now people's daily life is inseparable from the Internet. The information security of the Internet has attracted people's attention. For the information security of the Internet, many businesses The unit adopts the dual-machine dual-network operation mode in which the internal network and the external network are physically isolated. There are a large number of network connections from the access switch to the desktop computer, which has become a difficulty in the construction of the dual network. For the new network wiring, laying double line to achieve dual-network isolation, but for the transformation of the original line with only one network line, two methods are usually used, one is a wireless network, and the other is to re-add a new line, but the security and stability of the wireless network cannot be obtained. Guarantee, and in addition, the wiring is not only a heavy workload, but also damages the decoration of the building, affecting the appearance. Some buildings have complex structures and it is difficult to re-wiring
