CAT7 Network Cable

CAT7 network cable (Category 7 cable) is an 8-core shielded wire, each pair has a shielding layer (usually a metal foil shielded Foil Shield), and then there is a shielding layer outside the 8 cores (usually a metal braided wire mesh shielded Braided Shield), the interface is the same as RJ-45. Total shielding (usually metal braided screen shielding) + wire-pair shielding (usually metal foil shielding) Category 7 cable S/FTP Cat.7 (HSYVP-7) The highest transmission frequency is 600MHz, and the transmission frequency of Super Category 7 cables is 1000MHz

Knowledge about CAT7 cable

There are many significant differences between Category 6 and Category 7 cabling systems, the most obvious being bandwidth. The 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. A large number of broadband applications have prompted people to need more bandwidth.
For example, a typical Category 7 channel can provide a pair of wires with a bandwidth of 862MHZ to transmit video signals, another wire pair to transmit analog audio signals, and then a third and fourth wire pair to transmit high-speed LAN information. Another difference between Category 6 and Category 7 systems is their structure. Category 6 cabling systems can use UTP or STP. The Category 7 system is based only on shielded cables.
In the seven types of cables, each pair of wires has a shielding layer, and the four pairs of wires together have a common large shielding layer. From the physical structure point of view, the additional shielding layer makes the seven types of cables have a larger wire diameter.
Another important difference lies in its ability to connect to the hardware. The parameters of the seven types of systems require that all wire pairs provide at least 60DB of comprehensive near-end crosstalk when the connector is at 600MHz. However, the Category 5 system only requires 43dB at 100MHZ, and the value of Category 6 at 250MHZ is 46dB.
