Ikhebula le-ADSS izesekeli ziyizingxenye namathuluzi enzelwe i-All-Dielectric Self-Supporting (ADSS) izintambo ze-fiber optic. Lezi zesekeli zisebenza ukusekela, ukuhlanganisa, nokuvikela izintambo kunethiwekhi kagesi noma yezokuxhumana. Izibonelo ezijwayelekile yizibambo, amasethi okumiswa, ama-damper okudlidliza, kanye nemikhono yokuvikela. Zisindisa izintambo zakho emoyeni, emvuleni, nasekugobeni okungabangela ukulahleka kwesignali noma ukuphuka. Abafaki basebenzisa lezi zingxenye ukuqinisekisa ukuthi ikhebula liboshwe kahle futhi lihlala lizinzile iminyaka. Izesekeli ze-ADSS ezithembekile zinciphisa izindleko zokulungisa futhi zinciphise isikhathi sokungasebenzi. Ukuze sinqume ukuthi yisiphi isesekeli esifanelana kahle, iningi lethu libheka ukuthi hlobo luni lwekhebula esisebenza ngalo kanye nesimo sezulu sendawo. Funda ngezansi ukuze ubone ukuthi ungazikhetha futhi uzisebenzise kanjani ngendlela efanele.

I-OLT imele i-optical line terminal futhi iyithuluzi eliyinhloko ohlelweni lokuxhumana lwe-fiber-optic oludlulisela idatha futhi lwamukele idatha kusuka ezindaweni zomsebenzisi ezikude. Ama-OLT ahlala ekugcineni komhlinzeki wesevisi futhi asebenzisana nama-ONU amaningi noma ama-ONT emakhaya noma emabhizinisini. Lawa madivayisi asiza ekuphathweni kwethrafikhi, ekulawulweni komkhawulokudonsa, nasekugcineni idatha igeleza ngokushesha nangokushelela. Abathengi bahlangana nama-OLT kakhulu kumanethiwekhi e-fiber-to-the-home (FTTH), lapho i-inthanethi ethembeke kakhulu, eshesha kakhulu ibalulekile. Ama-OLT enza lula umsebenzi womhlinzeki wesevisi wokuphatha inani elikhulu labasebenzisi ngasikhathi sinye. Ukuze uqonde ukuthi ama-OLT asebenzisana kanjani nezinye izingxenye zenethiwekhi nokuthi kungani zibalulekile, isigaba esilandelayo sibheka ngokuningiliziwe imisebenzi yawo eyinhloko kanye nokucushwa.

I-An I-router ye-ONU iyidivayisi yenethiwekhi exhumanisa i-inthanethi ye-fiber optic kusuka kumhlinzeki iye kunethiwekhi yasekhaya noma yebhizinisi. Iguqula isignali ye-optical kusuka kumugqa we-fiber ibe yidatha engadliwa yifoni yakho, i-laptop, kanye ne-smart TV. Abantu abaningi bane-router ye-ONU lapho befaka i-inthanethi ye-fiber esheshayo, ngezinye izikhathi ezindaweni lapho ukuxhumana okusheshayo nokuzinzile kubaluleke kakhulu khona. Lawa ma-router ngokuvamile anezimbobo zokuxhumeka okunezintambo kanye ne-Wi-Fi eqinile ye-wireless. Ama-router awo e-ONU afakwa kalula ayizintandokazi zabasebenzisi, anamamodeli ezimo ezahlukene zokusetshenziswa, kusukela ekusetshenzisweni kwasekhaya okuvamile kuya emahhovisi amatasa. Okulandelayo kuxoxa ngezimpawu okufanele uzicabangele ku-router ye-ONU nokuthi isiza kanjani ngemisebenzi yansuku zonke eku-inthanethi.

Ukulungisa ikhebula le-fiber optic kubhekisela ekulungiseni amaphutha kanye namaphutha ezintanjeni ezidlulisa ulwazi njengama-pulse okukhanya. Ukulungisa ikhebula kudinga amathuluzi akhethekile kanye nobuchwepheshe obuthile ngoba i-fiber incane njengezinwele futhi iyaphuka. Abantu abenza lo msebenzi bavame ukusebenzisa i-fusion splicing noma i-mechanical splicing. Ukulungisa kungadinga i-fiber optic cleaver, umshini wokuhlanganisa kanye ne-power meter ukuqinisekisa ukusebenza kahle kokulungisa. Izinkinga ze-fiber zibangela ukuthi ukuxhumana kwewebhu noma kwefoni kubambezeleke noma kunciphe, ngakho ukulungisa okusheshayo kugcina konke kuhamba kahle. Abasebenzi abaningi basebenza emiseleni nasezindaweni ezinzima, kusukela ezindundumeni zasemadolobheni kuya emapulazini akude. Ukwazi inqubo kusindisa isikhathi futhi kuzinzise amanethiwekhi.

Izintambo ze-fiber optic zidlulisa idatha zisebenzisa ama-pulse okukhanya engilazini encane noma epulasitiki, okumelela enye yezindlela ezisheshayo zokuthutha ulwazi olukhona njengamanje. Lezi zintambo ziyingxenye ebalulekile kumanethiwekhi e-inthanethi, ocingweni, kanye ne-TV emhlabeni, zithwala inani elikhulu ledatha ebangeni elikhulu futhi zingonakalisi kakhulu. Izintambo ngayinye yakhiwa umgogodla, i-cladding, kanye ne-protective coating okusiza ukugcina izimpawu zinamandla futhi zicacile. Amabhizinisi amaningi, izikole, kanye nezibhedlela zithembele kuzo ukuze zithole ukuxhumana okuqhubekayo nokusheshayo. Yingakho bekhetha izintambo ze-fiber optic: isivinini, ukuphepha, kanye nokuqina esimweni sezulu esibi. Ngezansi uzothola amaqiniso nezeluleko ezilula ukuzigaya ukuze uqonde kangcono ukuthi lezi zintambo zithinta kanjani indlela esixhumana ngayo idatha.

Ukuze bakhethe ikhebula le-optical le-FTTH, abantu baqhathanisa izici ezifana nenani eliyinhloko, uhlobo lwekhebula, usayizi, kanye nokumelana nesimo sezulu. Izintambo ze-FTTH ziletha i-inthanethi kusuka kumhlinzeki ngqo ekhaya noma ehhovisi. Abasebenzisi abaningi bakhathazekile ngesivinini, ukuphepha, kanye nokufakwa okulula. Ezindaweni zasemadolobheni, izintambo zivame ukucindezelwa zibe yizindawo ezincane, kanti izindawo zasemakhaya zingadinga izintambo ezinde ezimelana nokushisa noma isimo sezulu esibandayo. Ochwepheshe baqinisekisa irediyasi egobile yekhebula, impahla yejakethi, nokuthi iyahambisana yini nekhodi yokwakha. Amathiphu alula asiza noma ubani ekukhetheni ikhebula elifanele izidingo zakhe kanye negumbi. Isigaba esilandelayo sihlaziya amaphuzu ayisihluthulelo okufanele acatshangelwe, ngakho ukukhetha ikhebula kubonakala kungasabisi kangako.

Umkhiqizi Wentambo Yesivikelo Sefayibha – Umkhiqizi wentambo yesivikelo sefayibha ukhiqiza izintambo ezixhumanisa amadivayisi enethiwekhi ukuze kudluliselwe idatha ngendlela ephumelelayo nethembekile. Lezi zintambo zisebenzisa imicu yengilazi noma yepulasitiki ukuze zidlulise amasignali ngokunciphisa okuncane kanye ne-bandwidth ephezulu, okwenza zibe yingxenye ebalulekile yengqalasizinda eminingi ye-inthanethi kanye nezokuxhumana. Ochwepheshe bezandla benza yonke intambo, besebenzisa izingxenye eziqinile kanye nokuhlolwa okuqinile ukuze bahambisane nezindinganiso zomhlaba wonke. Iningi linikeza izinketho zobude, uhlobo lokuxhuma, kanye nebanga lefayibha ukuze kuhambisane nezidingo ezahlukahlukene, kusukela ezikhungweni zedatha ezimatasa kuya kumalebhu esikole. Izintambo ezinhle zesivikelo zisho ukwehla okuncane kanye nokulungiswa okusheshayo lapho izinto zihamba eceleni. Ukuze sikusize ekukhetheni umhlinzeki ofanele, ingxenye enkulu yesihloko ixoxa ngalokho okufanele ukuhlole, abakhiqizi abaphezulu, kanye nezeluleko ezisetshenziswa kakhulu.

A intambo yesichibi se-fiber optic iyikhebula le-fiber optic elivalwe ngezixhumi kuzo zombili izinhlangothi. Basebenzisa lezi zintambo ukuxhuma imishini efana namaswishi, ama-router, namaphaneli okuhlanganisa idatha ukuze kudluliswe idatha ngokushesha. Zitholakala ngezinhlobo ezimbalwa, njengemodi eyodwa noma imodi eminingi, kuye ngezidingo zenethiwekhi. Ubude nesitayela sokuxhuma kuyahlukahluka, okwenza kube lula ukukhetha okufanele noma yikuphi ukuhlelwa. Lezi zintambo zisiza ukugcina amasignali enethiwekhi ehlanzekile futhi ezinzile, okubalulekile ezindaweni ezifana nezikhungo zedatha namahhovisi. Ukuqonda izisekelo zezintambo zokuhlanganisa i-fiber optic kwenza kube lula ukukhetha, ukufaka, kanye nokusetshenziswa. Umhlahlandlela wethu ophelele uchaza ukuthi zisebenza kanjani nokuthi ungakhetha kanjani efanele wena.
