Intambo ye-Ethernet emfutshane okanye ende: ungayikhetha njani?

i-ethernet yekhebula Mfutshane okanye mde: Ungakhetha njani ukusebenza kakuhle?

Xa useta inethiwekhi enentambo, ukukhetha ubude bentambo ye-Ethernet obuchanekileyo kubalulekile ukuze ufumane ulungelelwano phakathi kokusebenza, iindleko, kunye nokulula. Nantsi isikhokelo esikhawulezayo sokukunceda ukhethe phakathi kweentambo ezimfutshane nezinde.

1. Izinto eziqwalaselwayo malunga nokusebenza
Iintambo ze-Ethernet zinokuthumela idatha ngokuthembekileyo ukuya kuthi ga kwiimitha ezili-100 (iinyawo ezingama-328) ngaphandle kokuwohlokaI-DACAmandla esignali. Kwiifekthi ezininzi zasekhaya okanye eofisini, iintambo ezimfutshane (imitha e-1 ukuya kwe-10) zinciphisa ukuxinana kwaye zinciphisa ukubambezeleka, okuqinisekisa ukudluliselwa kwedatha ngokukhawuleza. Nangona kunjalo, iintambo ezinde (imitha ezili-15 ukuya ngaphezulu kwama-50) zibalulekile ekuqhagamsheleni izixhobo kwiindawo ezinkulu, ezinje ngamagumbi eenkomfa okanye izakhiwo ezinemigangatho emininzi. Soloko ukhetha. iintambo zeCat6 okanye zeCat7 ixesha elide, njengoko zibonelela ngokhuseleko olungcono kwaye zixhasa iibhendi eziphezulu.

2. Indawo yoFakelo
Iintambo ezimfutshane zilungele iindawo ezixineneyo (umz., iidesika, iindawo zokuzonwabisa) kwaye zinciphisa umngcipheko wokukhubeka. Kwiindawo ezinde zokufakelwa, linganisa umgama ofunekayo kwaye uphephe ukuzijika kakhulu, njengoko oku kunokubangela ukuphazamiseka kwe-electromagnetic. Cinga ngokusebenzisa izixhobo zokulawula iintambo, ezifana neekliphu okanye ii-conduit, ukugcina ufakelo lucocekile.

3. Ixabiso kunye nokuguquguquka
Iintambo ezimfutshane azibizi kakhulu kwaye zifumaneka lula. Iintambo ezinde zibiza kakhulu kodwa zibonelela ngokuguquguquka kotshintsho loyilo lwexesha elizayo. Kuphephe ukuthenga iintambo ezinde kakhulu "ukuba kunokwenzeka," kuba ukutyibilika okungasetyenziswanga kunokonakalisa umgangatho wesignali ngokuhamba kwexesha.NGOKUBA.
