Jumpers, as an important part of cabling systems, have not been given enough attention to testing issues. The testing issue of jumpers was only mentioned in the standard in the past two years
① TIA/EIA-568-A-4-1999: Transmission Delay and Delay Deviation Specification for 100 Ohm 4-Pair Cables
② TIA/EIA-568-A-5-2000:100 Ohm 4-pair Enhanced Category 5 Wiring Technical Specification
③ TIA/EIA-568-B Part 2: 100 Ω Balanced Twisted Pair Component Standard
Several standards have been published successively, which respectively involve the testing methods and requirements for jumpers in Ca.5 and Cat.5e. TIA/ELA-568B. 2-1 Class VI wiring standards have specific requirements for jumpers.
The original factory has a rigorous jumper process, adopts a multi-strand flexible cable design, and can withstand multiple times of repeated plugging and unplugging.
