Ndikulemba kuti ndipange Chingwe cha Ethernet Buku lotsogolera kugula. Tiyeni tiyambe ndi kukumbukira zomwe ndikudziwa za zingwe za Ethernet. Pali magulu osiyanasiyana, monga Cat5, Cat6, mwina apamwamba. Iliyonse ili ndi liwiro losiyana ndi bandwidth. Kenako palinso mbali yotetezera—zingwe zina zimakhala ndi zotchingira kuti zichepetse kusokoneza. Mitundu ya zolumikizira ndi RJ45, sichoncho? Komanso, kutalika kwa chingwe ndikofunikira; zingwe zazitali zitha kukhala ndi kuwonongeka kwa chizindikiro. Ndipo palinso mulingo wa jekete, monga PVC vs. plenum. Mwina kugwiritsa ntchito panja vs. mkati? Ndisaiwale kuti zingwe zina zimatsekeka pomwe zina zimakhala zolimba pakati, zomwe zimakhudza kusinthasintha ndi kulimba.

Tadikirani, bwanji za cholinga chake? Monga, pamasewera, kuwonera makanema, kapena kugwiritsa ntchito wamba. PoE (Power over Ethernet) nayonso ndi chinthu, kotero mawaya ena amafunika kuthana ndi zimenezo. Mtundu ukhoza kukhala chinthu chofunikira pa kukongola. Ma brand akhoza kukhala ofunika, koma mwina sangafunike pokhapokha ngati pali odalirika. Mitengo imasiyana malinga ndi gulu ndi mawonekedwe.

Ndiloleni ndikonze izi. Yambani ndi mawu oyamba ofotokoza zingwe za Ethernet ndi kufunika kwawo. Kenako gawani magawo: Magulu (Cat5e, Cat6, ndi zina zotero), Liwiro ndi Bandwidth, Kuteteza (UTP vs. FTP), Kutalika kwa Chingwe, Zolumikizira, Zinthu za Jacket (plenum, riser, outdoor), Zolimba vs. Stranded, PoE Support, Use Case (masewera, kunyumba, ofesi), Utoto, ndipo mwina gawo la malangizo achangu. Palinso FAQ.

Dikirani, ndikufunika kutsimikizira kutalika kwakukulu kwa gulu lililonse. Ndikuganiza kuti zingwe za Ethernet zili ndi kutalika kwakukulu kwa mamita 100 mosasamala kanthu za gulu, koma mwina magulu apamwamba amatha kusunga liwiro lalikulu kutalika kumeneko? Kapena kodi liwiro limatsika patali? Komanso, pamasewera, kuchedwa kochepa ndikofunikira, koma kodi gulu la zingwe limakhudza kuchedwa? Mwina osati mwachindunji, koma magulu apamwamba amathandizira bandwidth yayikulu yomwe ingakhale yabwino kwambiri potumiza deta mwachangu. Kuteteza kumathandiza ndi kusokoneza, komwe kungakhale kofunikira kwambiri m'malo omwe muli zamagetsi ambiri.

Yokhazikika poyerekeza ndi yolimba: Yolimba ndi yokhazikika, yokhazikika koma yogwira ntchito bwino patali. Yokhazikika ndi yosinthasintha, yabwino pa zingwe zomangira. Mitundu ya zotchingira: UTP siili ndi chitetezo, FTP ili ndi zotchingira zojambulazo, STP ili ndi zotchingira zoluka. Mwina fotokozani mawu ofupikitsa monga UTP, FTP, STP.

PoE: Magulu apamwamba angakhale abwino kwa PoE chifukwa amatha kugwiritsa ntchito mphamvu zambiri, makamaka pazida monga makamera kapena malo olowera. Komanso, ma gauge okhuthala (AWG yotsika) amatha kugwiritsa ntchito mphamvu zambiri. Mwina mungatchule AWG?

Utoto ndi wa dongosolo kapena kukongola kokha, sichoncho? Anthu ena angafune mitundu yosiyanasiyana ya zipinda kapena ntchito zosiyanasiyana.

Zipangizo za jekete: Zogwiritsidwa ntchito popangira ma ducts a mpweya, zogwiritsidwa ntchito pokweza ma payipi pakati pa pansi. Zingwe zakunja zimatetezedwa ndi UV komanso zimateteza madzi kuti asalowe.

Mu malangizo ogulira, perekani malingaliro owunikira zosowa kutengera liwiro la intaneti, malo (kusokoneza), mtundu wa kukhazikitsa (mkati mwa khoma, panja), ndi kuteteza mtsogolo. Mwina mungalimbikitse Cat6 kapena Cat6a pa kukhazikitsa kwatsopano chifukwa kumapereka magwiridwe antchito abwino komanso kungathandize mtsogolo.

Mafunso Ofunsidwa Kawirikawiri: Kodi kusiyana kwa Cat5e ndi Cat6 ndi kotani? Kodi ndingagwiritse ntchito chingwe chamtundu wapamwamba kuposa momwe ndikufunira? Kodi chitetezo chimakhudza bwanji magwiridwe antchito? Kodi kutalika kwa chingwe kumakhudza liwiro? Ndi chiyani chabwino kwambiri pamasewera? Kodi mungazindikire bwanji chingwe chapamwamba?

Dikirani, ndiyenera kuyang'ana ngati pali kusiyana kulikonse pa kuchuluka kwa ma curve kapena kapangidwe pakati pa magulu omwe amakhudza magwiridwe antchito. Komanso, mawu ngati AWG (American Wire Gauge) a makulidwe. Lower AWG amatanthauza mawaya okhuthala, omwe angakhale abwino kwambiri pa nthawi yayitali komanso PoE.

Ndikufunika kutsimikiza kuti chidziwitsocho ndi cholondola. Mwachitsanzo, Cat5e ndi 1 Gbps mpaka 100m, Cat6 imatha kuchita 10 Gbps mpaka 55m, Cat6a mpaka 100m pa 10 Gbps. Cat7 ndi Cat8 zili ndi ma specs apamwamba koma sizichitika kawirikawiri. Cat8 ndi ya malo osungira deta, mpaka 40 Gbps koma mtunda waufupi.

Komanso, tchulani kuti kwa ogwiritsa ntchito ambiri apakhomo, Cat5e kapena Cat6 ndi yokwanira pokhapokha ngati ali ndi mapulani a intaneti othamanga kwambiri. Pa maukonde apakhomo a 10 Gbps, Cat6a ingafunike. Zingwe zotetezedwa ndi zabwino m'malo omwe ali ndi zosokoneza zambiri, monga pafupi ndi zingwe zamagetsi kapena m'malo opangira mafakitale.

Mwina muphatikizepo tebulo lachidule loyerekeza magulu, liwiro, bandwidth, ndi momwe mungagwiritsire ntchito. Zimenezi zingathandize owerenga kuyerekeza mwachangu.

Ndiyeneranso kuzindikira kuti zolumikizira ziyenera kukhala ndi golide kuti zizitha kuyendetsa bwino komanso kuti zisawonongeke. Yang'anani ngati chingwecho chili ndi satifiketi (monga satifiketi ya UL) kuti muwonetsetse kuti chikukwaniritsa miyezo.

Mu malangizo okhazikitsa, tchulani kuti musapindire zingwe mwamphamvu kwambiri, pewani kuyenda motsatira zingwe zamagetsi kuti muchepetse kusokoneza, ndipo gwiritsani ntchito zomangira zingwe popanda kumangitsa kwambiri.

Tadikirani, kodi ndaphonya chilichonse? Mwina kusiyana pakati pa zingwe zomangira ndi zingwe zomangira. Zingwe zomangira zimapangidwa kale, pomwe zingwe zomangira zimapangidwa kuti zikhale ndi kutalika koyenera. Komanso, zingwe zosalala poyerekeza ndi zozungulira—zosalala zingakhale zosavuta kuziyika pansi pa makapeti koma sizingakwaniritse miyezo yofanana ndi ya zozungulira.

Komanso, zingwe zina zimakhala zoonda kapena zosinthasintha kwambiri, zomwe zingakhale zothandiza m'malo opapatiza. Komabe, sizingakhale zolimba kapena zogwira ntchito mofanana ndi zingwe wamba.

Ponena za makampani, mwina tchulani kuti makampani odziwika bwino monga Belkin, Monoprice, Cable Matters, ndi ena, ndi odalirika, koma pewani kuwapangitsa kuoneka ngati malonda.

Mukayika zonse pamodzi, bukuli liyenera kuyamba ndi chidule, kenako gawo lililonse likufotokoza mfundo zazikulu, kutsatiridwa ndi malangizo kutengera momwe zinthu zilili, ndi FAQ. Onetsetsani kuti chilankhulocho ndi chomveka bwino komanso chosavuta kuchigwiritsa ntchito, kupewa mawu ambiri aukadaulo koma chikhale chophunzitsa.
