What is the difference between Cat 7 jumper and Cat 6 jumper?
2011-05-18
Jumper wires are wires connecting two devices, usually straight wires. Patch cords and direct-connected network cables are more common. For patch cords, an important performance is the performance problem when bending. Since UTP twisted-pair cables are generally solid cores, they have poor manageability. One is that the cable is relatively hard, which is not conducive to bending, and the other is that the solid-core cable will have obvious return loss when it is bent, which causes the performance of the cable to decrease. Therefore, for the solid-core cable, there is generally a bending radius. Clear requirements. But for flexible cables with multi-strand cores specially used to manage jumpers, there are no such problems. The original jumper manufacturers have rigorous craftsmanship, adopt multi-strand flexible cord design, and can withstand repeated plugging and unplugging times. To order network patch cords, find Rui Lianpu, a professional wholesale manufacturer of seven types of patch cords, and you can visit the factory.
There are five types of jumpers, Category 6 jumpers, Category 7 jumpers and Category 8 jumpers, what is the difference between Category 7 jumpers and Category 6 jumpers?
1. There are differences in the use of broadband: six types of channels provide a comprehensive attenuation-to-crosstalk ratio of at least 200MHZ and an overall bandwidth of 250MHZ. The seven types of systems can provide a comprehensive attenuation-to-crosstalk ratio of at least 500MHZ and an overall bandwidth of 600MHZ. The performance improvement of Category 7 wiring is very obvious, making the transmission capacity and attenuation level provided by the copper cable medium close to the performance of optical fiber.
2. There are differences in structure: Category 6 wiring systems can use both UTP and STP, while Category 7 systems are only based on shielded cables. In the seven types of network cables, each pair of wires has a shielding layer, and the four pairs of wires together have a common large shielding layer. The non-RJ type seven wiring system adopts double-shielded cables, which can meet those areas where shielded twisted-pair systems are the mainstay.
3. It is different in its ability to connect to the hardware: the parameters of the seven types of jumpers require that all the wire pairs provide at least 60DB of comprehensive near-end cross-winding when the connector is at 600MHZ. And the super five system only requires 43DB at 100MHZ; the value of six types at 250MHZ is 46DB. Use the Internet at ordinary times, and the Internet speed is no higher than 100M. Ordinary Category 5 cables and Super Category 5 cables can fully meet the needs.
