Patch Cable Definition And Related Performance

    The "jumper" of the inside of the computer card is a small metal stick (jumper string) embedded in the motherboard, sound card, hard disk, etc., and a small clip (jumper clip) on the metal stick. The function of the jumper is to adjust the on-off relationship of different electrical signals on the equipment, and to adjust the working state of the equipment, such as determining the motherboard voltage, driver's master-slave relationship and so on. When the jumper clips are two jumpers at the same time, it indicates that the two jumpers are connected, and if only one or no sleeve is attached, it is disconnected. Adjustment jumper is very important, if the wrong, light is a panic, serious can even burn the entire device, so in the adjustment jumper must read the instructions carefully, check the jumper name, jumper column number and on-off relationship.Patch Cable
   Here the jumper is the copper connection line, by the standard jumper cable and the connection hardware is made, the jumper cable has two cores to eight cores unequal copper core, the connection hardware is two 6-bit or 8-bit module plugs, or they have one red white jumper or multiple bare head. Some jumpers at one end have a module plugs on the other end with 18-bit module slots, or fitted with 100P wiring plugs, mics, or module slots. The jumper is used to transfer a variety of links on the wiring rack, which can be used as a wiring rack or equipment connection cable. Modular jumper at both ends of the RJ45 joint, the use of Tia-Eia-568 needle structure, and flexible plug design to prevent loose and die. The jumper is 1 ft (0.305 m) to 500 ft (15.25 m) long, the most commonly used is 3 feet, 5 feet, 7 feet and 10 feet in length.Patch Cable
   The modular jumper is used in the workspace or as the jumper between the wiring. In the small office network or home network DIY installation, often referred to the dual-machine interconnect jumper. This jumper is not the standard jumper used in the integrated wiring, but a special hardware equipment connection line, it uses in the twisted pair line to connect two PCs pc directly, or two hub to pass RJ45 mouth butt, need crossover (commonly known as cross Connection line, jumper). It follows a specialized connection order.Patch Cable
   For jumpers, an important performance is the performance problem when bending, because UTP twisted pair is generally solid core, so it is poor in manageability performance. First, the cable is relatively hard, not conducive to bending, the second is the real wire core cable in the bending will have a very obvious return loss, resulting in the performance of the cable is reduced, so for solid wire core cables generally have a clear bending radius of the requirements. This is not the case with a flexible cable that is dedicated to managing the jumper's multiple-strand cores.Patch Cable
