Ubude bentambo ye-Ethernet ephezulu: Inokuba yintoni?

Ubude obuphezulu be i-ethernet yekhebulaIngaba yeyiphi na?
Umthetho wegolide weentambo ze-Ethernet zobhedu ezisemgangathweni (ezifana neCat5e, iCat6 kunye ikati6a) ziimitha ezili-100 (iinyawo ezingama-328). Ubude obuphezulu buquka yonke itshaneli: indlela intambo eyintloko esebenza ngayo kunye nazo naziphi na iintambo ezimfutshane zokubopha kwicala ngalinye.

Kutheni umda we-100m?
Ngaphaya kwalo mgama, imiqondiso yombane ehamba ngeentambo zobhedu iyancipha kakhulu ngenxa yokuthomalaliswa. Iingxaki zokuphazamiseka (ukuxoxa nge-crosstalk) kunye nokuvumelanisa imiqondiso nazo ziba yingxaki. Ukudlula iimitha ezili-100 kudla ngokubangela isantya esicothayo, uqhagamshelo olungenaxesha, okanye ukusilela ngokupheleleyo.

Ngaba ufuna ukuya phambili? Unezinketho:

Iiswitshi/iihubhu zenethiwekhi: Ukubeka isixhobo esisebenzayo, esifana neswitshi okanye ihabhu, ngaphambi kokuba uphawu lwe-100m lusete kwakhona ikhawuntara yomgama. Oku kukuvumela ukuba wenze iisegments ze-daisy-chain (nganye

Izandisi ze-Ethernet: Ezi zixhobo zikhethekileyo ziguqula isignali ukuze idluliselwe kumgama omde, ngamanye amaxesha zisebenzisa iintambo ezahlukeneyo, ezifana nentambo ye-coaxial okanye imigca ye-DSL, enokufikelela kwiikhilomitha. Iintambo ze-Fiber optic: Kwiisithuba ezinde kakhulu (amakhulu eemitha okanye iikhilomitha) kunye nokusebenza okuphezulu, iintambo ze-fiber optic zezona sisombululo sifanelekileyo, nangona zifuna ii-transceivers ezihambelanayo kuzo zonke iziphelo.
