Kumvetsetsa Cholumikizira cha RJ45: The Backbone of Wired Networks!
Lowani kudziko la Ethernet networking ndi chiwongolero chokwanira pa cholumikizira cha RJ45, kapangidwe kake, ndi gawo lake lofunikira pakutumiza kwa data mwachangu.
Ethernet ndi RJ Standards:
Ukadaulo wa Ethernet umathandizira kulumikizana kosasunthika pakati pa zida zingapo mkati mwa netiweki, motsogozedwa ndi ma protocol ena omwe amatsimikizira kulumikizana koyenera. Ma Jack Olembetsedwa (RJ) ndi mawonekedwe ofananirako omwe amapangidwira ma media osiyanasiyana. Pakati pawo, RJ45, RJ11, RJ48, ndi RJ61 ndizofala, zomwe zimapangidwira ntchito zapadera mkati mwa maukonde a Ethernet.
Cholumikizira cha RJ45:
Chojambulira cha RJ45, chomwe chimadziwika kuti Registered Jack 45, chakhala chodziwika bwino pamalumikizidwe amawaya. Poyambirira idapangidwira makina amafoni, idasintha kuti ikhale ponseponse pa intaneti ya Ethernet. "45" mu RJ45 imayimira mindandanda yake yapadera mkati mwa jack yolembetsedwa.
Zokonda Zaukadaulo:
Yodziwika ndi mawonekedwe ake okulirapo poyerekeza ndi zingwe zafoni, cholumikizira cha RJ45 chimakhala ndi bandwidth yokulirapo, yomwe imafika mpaka 10 Gbps. Kuthekera kothamanga kwambiri kumeneku, kophatikizidwa ndi zida zotetezedwa, kumayika RJ45 ngati cholumikizira chosankha cholumikizira makompyuta anu ndi ma seva, ma routers, ndi ma network ena.
Kapangidwe Kapangidwe:
Cholumikizira cha RJ45 chili ndi kasinthidwe ka pini 8, kotchedwa 8P8C, kulola kulumikizidwa kwa mawaya asanu ndi atatu. Nthawi zambiri amaphatikizidwa ndi Shielded Twisted Pair (STP) kapena Unshielded Twisted Pair (UTP) zingwe, cholumikizira cha RJ45 cholumikizira pulasitiki chowonekera chimapereka mawonekedwe omveka bwino a waya wamkati.
Miyezo ya Wiring:
Akayang'anitsitsa, munthu amatha kuwona mawaya asanu ndi atatu osiyana mkati mwa cholumikizira cha RJ45, chosiyanitsidwa ndi mitundu yolimba komanso yamizeremizere. Mawaya a RJ45 amagawidwa motengera momwe amagwirira ntchito, okhala ndi magulu monga Cat 5e, Mphaka 6, ndi Mphaka 7, iliyonse imapereka milingo yosiyana ya kufalikira ndi bandwidth.
Mitundu ya Coding ndi Miyezo:
Kuyika kwamtundu wa mawaya a RJ45 kumakhazikika kuti zithandizire kuzindikira komanso kulumikizana. Pali mitundu iwiri yoyambira yamitundu: T568A ndi T568B. Muyezo wa T568A umayika mawaya obiriwira pamaso pa lalanje, pomwe T568B imatembenuza izi. T568A imatsimikizira kuyanjana kwambuyo ndi makina opangira mawaya olowa, pomwe T568B idapangidwa kuti ichepetse phokoso lazizindikiro, kupititsa patsogolo kukhulupirika kwa ma data.
Chonde titumizireni kuti mudziwe zambiri zamalonda ndi ma Catalog.
