A comparison was made between regular jumpers and cross connect cables. Ordinary jumper (straight line): used to connect different devices, such as computer network cards and modules, patch panels and wiring, and patch panels and HUB or switches. The RJ45 connector wiring method at both ends of the straight line is the same, using the T568B standard wire sequence.
Cross connect line: used to connect the same equipment, such as HUB and switches. The RJ45 wiring methods at both ends are different, using T568B and T568A standards respectively. It is required that one of the wiring pairs be swapped for 1/3 and 2/6 pairs, while the other pairs can still be installed in a one-to-one correspondence.
In the integrated wiring (online) intelligent management system, an identification jumper is also used, which is actually a composite jumper or multifunctional jumper. Usually, in addition to four pairs of wires, a wire is added, which is composed of copper wire or fiber optic, and is used to connect corresponding detection equipment for real-time detection and management of the wiring system.
