Ngibhala ukuze ngidale Ikhebula le-Ethernet umhlahlandlela wokuthenga. Ake siqale ngokukhumbula engikwaziyo ngamakhebula e-Ethernet. Kunezigaba ezahlukene, njenge-Cat5, i-Cat6, mhlawumbe eziphakeme. Ngayinye inejubane elihlukile kanye nobubanzi bomkhawulokudonsa. Bese kuba khona isici sokuvikela—ezinye izintambo zinezivikelo zokunciphisa ukuphazamiseka. Izinhlobo zezixhumi ziyi-RJ45, akunjalo? Futhi, ubude bekhebula bubalulekile; izintambo ezinde zingase zibe nokuwohloka kwesiginali. O, futhi kukhona isilinganiso sejakethi, njenge-PVC vs. plenum. Mhlawumbe ukusetshenziswa kwangaphandle vs. ngaphakathi? Mangingakhohlwa ukuthi ezinye izintambo zibambekile kanti ezinye ziqinile, okuthinta ukuguquguquka nokuqina.

Linda, kuthiwani ngenhloso? Njengokudlala imidlalo, ukusakaza, noma ukusetshenziswa okuvamile. I-PoE (Amandla phezu kwe-Ethernet) nayo iyinto, ngakho-ke amanye amakhebula adinga ukusingatha lokho. Umbala ungase ube yinto okufanele icatshangelwe ekubukekeni. Imikhiqizo ingaba yinto ebalulekile, kodwa mhlawumbe ayidingeki ngaphandle kokuthi kukhona ethembekile. Intengo iyahlukahluka kuye ngesigaba nezici.

Ake ngihlele lokhu. Qala ngesingeniso esichaza izintambo ze-Ethernet nokubaluleka kwazo. Bese uhlukanisa izigaba: Izigaba (i-Cat5e, i-Cat6, njll.), Isivinini kanye ne-Bandwidth, Ukuvikela (i-UTP vs. FTP), Ubude Bekhebula, Izixhumi, Izinto Zejakhethi (i-plenum, i-riser, yangaphandle), Okuqinile vs. Okuqinile, Ukusekelwa kwe-PoE, Ikesi Lokusetshenziswa (imidlalo, ikhaya, ihhovisi), Umbala, kanye nesigaba samathiphu asheshayo. Faka futhi i-FAQ.

Linda, ngidinga ukuqinisekisa ubude obuphezulu besigaba ngasinye. Ngicabanga ukuthi izintambo ze-Ethernet zinobude obuphezulu bamamitha ayi-100 kungakhathaliseki isigaba, kodwa mhlawumbe izigaba eziphakeme zingagcina isivinini esiphezulu kulolo bude? Noma ingabe isivinini siyehla ngebanga? Futhi, emidlalweni, ukubambezeleka okuphansi kubalulekile, kodwa ingabe isigaba sekhebula sithinta ukubambezeleka? Mhlawumbe hhayi ngokuqondile, kodwa izigaba eziphakeme zisekela i-bandwidth ephezulu okungaba ngcono ekudlulisweni kwedatha okusheshayo. Ukuvikela kusiza ngokuphazamiseka, okungaba kubaluleke kakhulu ezindaweni ezinama-elekthronikhi amaningi.

I-Stranded vs. solid: I-Solid core yenzelwe ukufakwa okuhlala njalo, ayiguquguquki kakhulu kodwa isebenza kangcono emabangeni amade. I-Stranded iguquguquka kakhudlwana, ilungele izintambo ze-patch. Izinhlobo zokuvikela: I-UTP ayivikelwe, i-FTP inesivikelo se-foil, i-STP inesivikelo esilukiwe. Mhlawumbe chaza izifinyezo ezifana ne-UTP, FTP, STP.

I-PoE: Izigaba eziphakeme zingase zibe ngcono kwi-PoE ngoba zingaphatha amandla amaningi, ikakhulukazi kumadivayisi afana namakhamera noma izindawo zokufinyelela. Futhi, amageyiji amakhulu (i-AWG ephansi) angaphatha amandla amaningi. Mhlawumbe usho i-AWG?

Umbala ungowokuhlela noma ubuhle kuphela, akunjalo? Abanye abantu bangase bafune imibala ehlukene yamakamelo noma ukusetshenziswa okuhlukile.

Izinto zejakethi: Isilinganiso se-Plenum semipayipi yomoya, isilinganiso se-riser semigijimo eqondile phakathi kwezitezi. Izintambo zangaphandle zinesivikelo se-UV kanye nokuvimbela amanzi.

Kumathiphu omhlahlandlela wokuthenga, phakamisa ukuhlola izidingo ngokusekelwe kwisivinini se-inthanethi, indawo (ukuphazamiseka), uhlobo lokufakwa (odongeni, ngaphandle), kanye nokuvikela ikusasa. Mhlawumbe ncoma i-Cat6 noma i-Cat6a ekufakweni okusha njengoba kunikeza ukusebenza okungcono futhi kuvikela ikusasa.

Imibuzo Evame Ukubuzwa: Uyini umehluko phakathi kwe-Cat5e ne-Cat6? Ngingayisebenzisa ikhebula lesigaba esiphezulu kunalokho okudingekayo? Ukuvikela kuthinta kanjani ukusebenza? Ingabe ubude bekhebula buthinta isivinini? Yini engcono kakhulu yokudlala imidlalo? Ungayibona kanjani ikhebula lekhwalithi?

Linda, kufanele ngihlole ukuthi kukhona yini umehluko enanini lokujika noma ukwakhiwa phakathi kwezigaba ezithinta ukusebenza. Futhi, amagama afana ne-AWG (American Wire Gauge) okuwubukhulu. I-AWG ephansi isho izintambo ezijiyile, ezingaba ngcono kuma-run amade kanye ne-PoE.

Ngidinga ukuqinisekisa ukuthi ulwazi lunembile. Isibonelo, i-Cat5e ingu-1 Gbps kuze kufike ku-100m, i-Cat6 ingenza i-10 Gbps kuze kufike ku-55m, i-Cat6a kuze kufike ku-100m ku-10 Gbps. I-Cat7 ne-Cat8 zinemininingwane ephezulu kodwa azivamile. I-Cat8 ingeyezikhungo zedatha, kuze kufike ku-40 Gbps kodwa ibanga elifushane.

Futhi, phawula ukuthi kubasebenzisi abaningi basekhaya, i-Cat5e noma i-Cat6 yanele ngaphandle kokuthi banezinhlelo ze-inthanethi ezisheshayo kakhulu. Kumanethiwekhi asekhaya angu-10 Gbps, i-Cat6a ingadingeka. Izintambo ezivikelwe zilungele izindawo ezinokuphazamiseka okukhulu, njengezintambo zikagesi noma ezindaweni zezimboni.

Mhlawumbe faka ithebula elisheshayo lokubhekisela eliqhathanisa izigaba, isivinini, umkhawulokudonsa, kanye nezimo zokusetshenziswa. Lokho kungasiza abafundi ukuqhathanisa ngokushesha.

Kufanele futhi ngiqaphele ukuthi izixhumi kufanele zifakwe igolide ukuze kube nokuguquguquka okungcono kanye nokumelana nokugqwala. Hlola ukuthi ikhebula liqinisekisiwe yini (njengesitifiketi se-UL) ukuqinisekisa ukuthi liyahlangabezana nezindinganiso.

Ezindleleni zokufaka, khuluma ngokungagobi izintambo ngokucijile kakhulu, gwema ukusebenzisana nezintambo zikagesi ukuze unciphise ukuphazamiseka, futhi usebenzise izintambo zekhebula ngaphandle kokuqinisa kakhulu.

Linda, kukhona engikuphuthelwe? Mhlawumbe umehluko phakathi kwezintambo zokubopha kanye nezintambo ezinkulu. Izintambo zokubopha zenziwe kusengaphambili, kanti ezinkulu zenzelwe ubude obujwayelekile. Futhi, izintambo ezisicaba vs. eziyindilinga—ezisicaba zingase zibe lula ukuzihambisa ngaphansi kwamakhaphethi kodwa zingase zingahlangabezani nezindinganiso ezifanayo nezeziyindilinga.

Futhi, ezinye izintambo zincane noma ziguquguquka kakhulu, okungaba usizo ezindaweni ezixinene. Kodwa-ke, zingase zingabi nokuqina noma ukusebenza okufanayo nezintambo ezijwayelekile.

Ngokuphathelene nemikhiqizo, mhlawumbe khuluma ngokuthi imikhiqizo edumile njengeBelkin, Monoprice, Cable Matters, njll., ithembekile, kodwa gwema ukuyenza ibonakale njengesikhangiso.

Uma konke lokhu sekuhlanganisiwe, umhlahlandlela kufanele uqale ngokubuka konke, bese kuba yisigaba ngasinye esichaza izici ezibalulekile, kulandelwe izincomo ezisekelwe esimweni sokusetshenziswa, kanye ne-FAQ. Qiniseka ukuthi ulimi lucacile futhi lufinyeleleka kalula, ugweme amagama amaningi obuchwepheshe kodwa asanikeza ulwazi.
