[AipuWaton] Kuelewa Waya Nane katika Kebo za Ethaneti: Kazi na Mbinu Bora

Kuunganisha nyaya za mtandao mara nyingi kunaweza kutatanisha, hasa unapojaribu kuamua ni nyaya zipi kati ya nane za shaba ndani ya kebo ya Ethaneti ni muhimu kwa kuhakikisha upitishaji wa kawaida wa mtandao. To clarify this, it is important to understand the overall function of these wires: they are designed to reduce electromagnetic interference (EMI) by twisting pairs of wires together at specific densities. This twisting allows the electromagnetic waves produced during the transmission of electrical signals to cancel each other out, effectively eliminating potential interference. The term "twisted pair" aptly describes this construction.

Katika mitandao mingi ya Fast Ethernet, ni viini vinne tu kati ya nane (1, 2, 3, na 6) hutimiza majukumu katika kutuma na kupokea data. Waya zilizobaki (4, 5, 7, na 8) ni za pande mbili na kwa ujumla zimehifadhiwa kwa matumizi ya baadaye. Walakini, katika mitandao inayozidi Mbps 100, ni mazoea ya kawaida kutumia waya zote nane. Katika hali hii, kama vile nyaya za Kitengo cha 6 au cha juu zaidi, kutumia tu sehemu ndogo ya core kunaweza kusababisha uthabiti wa mtandao kuathiriwa.

Upon stripping an Ethernet cable, you'll notice the twisting density of the wire pairs varies significantly. Jozi zinazohusika na uwasilishaji wa data—kawaida jozi za rangi ya chungwa na kijani—zimepindishwa kwa nguvu zaidi kuliko zile zilizotengwa kwa ajili ya kuweka msingi na utendaji mwingine wa kawaida, kama vile jozi za kahawia na bluu. Therefore, adhering to the T568B wiring standard when crafting patch cables is crucial for optimal performance.
