[AipuWaton] Ukuqonda iiNcingo eziSibhozo kwiiCables ze-Ethernet: Imisebenzi kunye neZiqhelo ezilungileyo

640 (2)

Ukuqhagamshela iintambo zothungelwano kudla ngokubhideka, ngakumbi xa uzama ukufumanisa ukuba zeziphi iingcingo zobhedu ezisibhozo ezingaphakathi kwe-Ethernet cable eziyimfuneko ekuqinisekiseni ukuhanjiswa kwenethiwekhi okuqhelekileyo. Ukucacisa oku, kubalulekile ukuqonda umsebenzi opheleleyo wezi ngcingo: ziyilelwe ukunciphisa ukuphazamiseka kwe-electromagnetic interference (EMI) ngokujija izibini zeengcingo kunye kuxinaniso oluthile. Oku kujijisa kuvumela amaza e-electromagnetic aveliswa ngexesha lokuhanjiswa kweempawu zombane ukuba arhoxise omnye komnye, aphelise ngokufanelekileyo ukuphazamiseka okunokwenzeka. Igama elithi "isibini esijijekileyo" lichaza ngokufanelekileyo olu lwakhiwo.

Ukuzivelela kwezibini ezijijekileyo

Izibini ezijijekileyo ekuqaleni zazisetyenziselwa ukuhanjiswa komqondiso womnxeba, kodwa ukusebenza kwazo kwakhokelela ekwamkelweni kwazo ngokuthe ngcembe kugqithiso lomqondiso wedijithali ngokunjalo. Okwangoku, iindidi ezisetyenziswa kakhulu ziCandelo 5e (Cat 5e) kunye neCandelo lesi-6 (Ikati 6) izibini ezijijekileyo, zombini ziyakwazi ukufezekisa i-bandwidths ukuya kwi-1000 Mbps. Nangona kunjalo, umda obalulekileyo weentambo ezimbini ezijijekileyo ngumgama wabo omkhulu wothumelo, oqhele ukungagqithi kwi-100 leemitha.

Kubalulekile ukuqaphela ukuba ukunkqaya iodolo ye-T568A akuyomfuneko xa kujongwa ukuxhaphaka kwayo okuhlileyo. Ukuba kuyimfuneko, unokufezekisa lo mgangatho ngokulula ngokutshintshanisa iingcingo 1 kunye no-3 kunye no-2 kunye no-6 ngokusekelwe kuqwalaselo lwe-T568B.

Uqwalaselo lweeNcingo kwiiNkqubo ezahlukeneyo

Ukusetyenziswa okusemgangathweni usebenzisa iCandelo 5 kunye neCandelo 5e izibini eziphothiweyo, izibini ezine zeengcingo-ngoko ke, iintambo ezisibhozo ezipheleleyo-zisetyenziswa ngokuqhelekileyo. Uthungelwano olusebenza phantsi kwe-100 Mbps, uqwalaselo oluqhelekileyo lubandakanya ukusebenzisa iingcingo 1, 2, 3, kunye no-6. Umgangatho oqhelekileyo wocingo, owaziwa ngokuba yi-T568B, ucwangcisa ezi ngcingo kuzo zombini iziphelo ngolu hlobo lulandelayo:

Kwiinethiwekhi ezininzi ze-Ethernet ezikhawulezayo, ezine kuphela kwii-cores ezisibhozo (1, 2, 3, kunye ne-6) zizalisekisa iindima zokudlulisa kunye nokufumana idatha. Iingcingo eziseleyo (4, 5, 7, kunye ne-8) zimbini kwaye zigcinelwe ukusetyenziswa kwixesha elizayo. Nangona kunjalo, kuthungelwano olungaphezulu kwe-100 Mbps, yinkqubo eqhelekileyo ukusebenzisa zonke iingcingo ezisibhozo. Kule meko, njengoluhlu lwe-6 okanye iintambo eziphezulu, ukusebenzisa kuphela i-subset ye-cores kunokukhokelela ekuzinzeni kwenethiwekhi.

Injongo yocingo ngalunye

Ukuze uqonde ngcono ukuba kutheni iingcingo 1, 2, 3, 6 zisetyenziswa, makhe sijonge iinjongo ezithile zondoqo ngamnye:

Ukubaluleka koXinano lwezibini eziJikiweyo kunye nokuKhuselwa

Ekuqhaqheni intambo ye-Ethernet, uya kuqaphela ukuxinana kweengcingo zeengcingo zahluka kakhulu. Izibini ezijongene nokuhanjiswa kwedatha-ngokuqhelekileyo izibini ezi-orenji kunye nohlaza-zijijene ngokuqina ngakumbi kunezo zabelwe ukubeka phantsi kunye neminye imisebenzi eqhelekileyo, efana nezibini ezimdaka kunye neblue. Ke ngoko, ukubambelela kumgangatho we-T568B wocingo xa kuyilwa iintambo zokuvala kubalulekile ekusebenzeni kakuhle.

Iingcamango Eziphosakeleyo eziqhelekileyo

Akuqhelekanga ukuva abantu besithi, "Ndikhetha ukusebenzisa ilungiselelo lam xa ndisenza iintambo; ngaba kwamkelekile oko?" Ngelixa kusenokubakho ukuguquguquka okuthile kusetyenziso lobuqu ekhaya, kucetyiswa kakhulu ukuba ulandele ii-odolo zocingo ezisekiweyo kwiimeko zobuchwephesha okanye ezibalulekileyo. Ukutenxa kule migangatho kunokujongela phantsi ukusebenza kakuhle kweentambo ezimbini ezijijekileyo, okukhokelela kwilahleko ebalulekileyo yothumelo lwedatha kunye nomgama ocuthiweyo wothumelo.

Ukuqukumbela

Ngamafutshane, ukuba uthatha isigqibo sokucwangcisa iingcingo ngokusekelwe kukhetho lomntu, qiniseka ukubeka iingcingo ezi-1 kunye ne-3 kunye kwisibini esijijekileyo, kunye neengcingo ze-2 kunye ne-6 kunye kwesinye isibini esijijekileyo. Ukulandela ezi zikhokelo kuya kuqinisekisa ukuba inethiwekhi yakho isebenza ngokufanelekileyo nangokuthembekileyo.
