The network jumper cable is also called the finished
Network Cable, which refers to the network cable with crystal plugs connected at both ends of the network cable. The injection molded short-meter finished network cable is often used for the connection between the host and the router;
The network jumper is a core composed of multiple strands of thin copper wire conductors, which has good flexibility to ensure that the jumper is very convenient during use. The internal structure is 7 strands of copper wire, generally 7 * 0.08 / 7 * 0.1 / 7 * 0.12 / 7 * 0.16 / 7 * 0.20.
Network jumpers are generally divided into Category 5, Category 6, Category 6, Category 7 and Category 8; Category 5 jumpers are generally used in 100M networks, and Category 6 jumpers are generally used in Gigabit networks and are compatible with 100M networks. For networks, when using Category 6 jumpers, switches and routers must be replaced with gigabit switches and routers to transmit gigabit networks. Category 6 is mainly used in gigabit networks. In terms of transmission frequency, it is also 200-250 MHz like Category 6 lines, and the maximum transmission speed can also reach 1 000 Mbps, but it is greatly improved in terms of crosstalk, attenuation and signal-to-noise ratio. Category 7 is a shielded twisted pair cable, so its transmission frequency can reach at least 500 MHz, which is more than twice that of Category 6 and Super Category 6, and the transmission rate can reach 10 Gbps. Category 8 network cable is the latest generation of double-shielded (SFTP) network jumpers. It has two wire pairs, can support 2000MHz bandwidth, and the transmission rate is up to 40Gb/s, but its maximum transmission distance is only 30m, so it is generally used The connection of servers, switches, patch panels and other equipment in short-distance data centers.
