Kwenza kube lula ukubona ngokushesha izintambo, izixhumi, kanye nezintambo, okwenza umsebenzi wenziwe ngokushesha ngaphandle kokudideka okuningi. Uma unezindinganiso zombala ezicacile, ukulungiswa kokuxazulula izinkinga kanye nokugcinwa kwehle kancane kusukela ekushayweni okubi kuya emsebenzini ocasulayo kancane. Kungakhathaliseki ukuthi uphatha amajakethi, izintambo ze-pigtail, noma izintambo zangaphakathi, lawa makhodi enza kube lula kuzo zonke izigaba.

Ukuba naleli shadi lekhodi yombala elitholakalayo kuzokusiza wonge isikhathi futhi uhlale uhlelekile. Ukuqonda kangcono izisekelo kuholela emaphutheni ambalwa kanye nomsebenzi obushelelezi kakhulu. I-Fiber optics ingaba yinto eyesabekayo, kodwa lawa makhodi ombala aqondile asiza ekubekeni yonke into ngendlela ehlelekile.

Sebenzisa lawa makhodi ombala ukuze uzuze ukuze abasebenzisi bakwazi ukubona kalula inhloso yokuxhumana ngakunye. Balapha ngempela ukuze babe abangane bakho. Uma usebenzisa la magama amaningi, kulapho ezoba ngumuntu wesibili khona.

imibuzo ejwayelekile ukubuzwa

Kuyini ukufaka ikhodi yombala we-fiber optic?

Ukubhala ikhodi yombala ye-fibre optic kuyindlela evamile yokuhlukanisa imicu ngayinye ezintanjeni ezinkulu ze-fibre optic. I-fibre ngayinye inikezwa ikhodi yombala ehlukile ukuze kube lula ukuhlonza i-fibre ngayinye ngesikhathi sokufakwa, ukulungiswa, kanye nokuxazulula izinkinga.

Kungani amakhodi ombala we-fiber optic ebalulekile?

Ngamafuphi, amakhodi emibala avumela ukuhlonza okusheshayo nokunembile imicu ngaphakathi kwendwangu yokuthunga, okunciphisa amathuba amaphutha ngesikhathi sokuxhuma, ukulungisa, noma ukuthuthukisa inethiwekhi. Andisa umkhiqizo futhi agwema amaphutha abizayo kumanethiwekhi e-fiber optic.

Yimaphi amakhodi ombala we-fiber optic ajwayelekile?

Amakhodi ombala we-fiber optic ajwayelekile asekelwe ezindinganisweni zombala ze-TIA/EIA-598-C. I-fiber ngayinye ekhebulani inekhodi yayo yombala. Iqala ngombala oluhlaza okwesibhakabhaka, bese iya ku-orenji, eluhlaza okwesibhakabhaka, onsundu, njalo njalo ngokulandelana okunqunyiwe kwemibala engu-12.

Isho ukuthini imibala yokuxhumanisa?

Imibala yesixhumi esetshenziswa ukuhlonza uhlobo lwefayibha. Ekubukeni okuphezulu kuya phansi ngenhla, phawula, isibonelo, ukuthi izixhumi eziluhlaza okwesibhakabhaka zibonisa ifayibha yemodi eyodwa kuyilapho izixhumi ze-beige noma ze-aqua zibonisa ifayibha yemodi eminingi. Lokhu kuvumela ochwepheshe ukuthi bakwazi ukubona kalula izinhlobo ezahlukene zefayibha ngokushesha.

Ingabe imibala yejakethi yekhebula inezincazelo ezithile?

Yebo, kwezinye izimo, imibala yejakethi yekhebula ikhombisa uhlobo lwefayibha. Okuphuzi ngokuvamile kusetshenziselwa ukumela ifayibha yemodi eyodwa, i-orenji noma i-aqua yefayibha yemodi eminingi, kuyilapho eminye imibala ingase isetshenziselwe izinhlelo ezithile. Lokhu kwenza kube lula kakhulu ukutshela ukuthi into ethile iyini nokuthi isetshenziswa kanjani.

Ukhumbula kanjani amakhodi ombala we-fiber optic?

Ukusebenzisa amadivayisi okukhumbula noma amashadi ekhodi yombala kuyindlela yokuqala kalula ukukhumbula amakhodi ombala wefayibha. Isibonelo, ukusebenzisa umusho ofana nokuthi “Ama-Orange Amakhulu Akhula Kakhulu” kungasiza ekukhumbuleni ukulandelana: okuluhlaza okwesibhakabhaka, okuwolintshi, okuluhlaza okotshani, kanye nokunsundu.

Ingabe amakhodi ombala wefayibha yangaphakathi ahlukile kwawangaphandle?

Cha, ikhodi yombala wefayibha yangaphakathi inamathela ezindinganisweni ezifanayo ze-TIA/EIA-598-C njengezintambo zangaphandle. Lokhu kuvumelana kwenza kube lula ukubona nokuphatha kuzo zonke izinhlobo zezintambo.
