Intambo yefiber optic yintambo yenethiwekhi equle imida yentambo yeglasi ngaphakathi kwendawo yokukhupha. Ziye zenzelwe umgama omde, uxhumano lwentsebenzo ephezulu kakhulu, kunye ne-telecommunications.
Ukuthelekiswa neentambo ezicutshungulwayo, iintambo ze-fiber optic zibonelela ngokubanzi kwaye ziyakwazi ukudlulisela idatha kwiimitha ezide.
Iifayili ze-Fiber optic zixhasa ininzi ye-intanethi yehlabathi, ithelevishini ye-cable kunye neefowuni.
Indlela iiFiber Optic Cables zisebenza ngayo
Iifayili ze-Fiber optic zithwala iimpawu zokunxibelelana usebenzisa i-pulses of light generated by lasers ezincinane okanye idiode ezikhanyayo (ii-LED).
Ikhebula liqukethe enye okanye ngaphezulu kweglasi, nganye ilula kakhulu kunene inwele yabantu. Iziko le-strand nganye libizwa ngokuba yintloko, enika indlela yokukhanya ukuhamba. Ingqungquthela ijikelezwe ngqongqelo lweglasi ebizwa ngokuba yi-cladding ebonisa ukukhanya kwangaphakathi ukuze kugweme ukulahlekelwa kwesignali kwaye uvumele ukukhanya kudlule kwi-bends kwi-cable.
Iintlobo ezimbini ezibalulekileyo zetambo zefiber zibizwa Imodi enye kunye nefayili yefayili. I-fiber yefowuni enye isebenzisa i-glass thin thin and a laser ukuvelisa ukukhanya ngelixa iifom ze-multi-mode zisebenzisa ii-LED.
Iimodeli zefayili zodwa zisoloko zisebenzisa amaCandelo eWeve Division Multiplexing (WDM) ukunyusa inani lezithuthi zendlela ezingathunyelwa ngaphaya komgca. I-WDM ivumela ukukhanya kwii-longvels ezahlukeneyo eziza kuhlanganiswa (multiplexed) kwaye zihlukaniswe kamva (de-multiplexed), ngokugqithiseleyo zithumela imilambo yonxibelelwano emininzi ngokuphambuka kombane omnye.
Izibonelelo zeeFiber Optic Cables
Iifayili zeFiber zibonelela ngeenzuzo ezininzi ngaphezu kwekhamera yecala yobuncinane obude.
- I-Fiber optics inegunya eliphezulu. Isixa somnxeba womnatha wefayili i-fiber i-cable iyakuthwala ngokugqithiseleyo ngaphezu kwekhebhu yentsimbi ene-thickness efanayo. Iifayili zeFiber zilinganiswe kwi-10 Gbps, i-40 Gbps kunye ne-100 Gbps ziqhelekileyo.
- Ekubeni ukukhanya kunokuhamba iindawo ezide kude phantsi kwefayibha ngaphandle kokulahlekelwa amandla ayo, kunciphisa imfuneko yokukhuthaza izibonakaliso.
- I-Fiber ayinakuphazamiseka. Intambo yenethiwekhi yesintu idinga ukukhusela okhethekileyo ukukhusela ekuphazamiseni kwe-electromagnetic. Ngeli xesha ukukhusela kukunceda, akunakwanela ukukhusela ukuphazamiseka xa iintambo ezininzi zihlangene ndawonye ngokusondelelana. Izakhiwo ezibonakalayo zeglasi kunye nezixhobo zefiber ziphepha ininzi yale micimbi.
IFiber kwiKhaya (FTTH), ezinye iiNtshukumo, kunye neeFiber Networks
Nangona ininzi ifayili ifakwe ukuxhasa uxhulumaniso olude phakathi kweedolophu nakwamanye amazwe, abanye ababoneleli ngee-intanethi bahlala batyala imali yokufakela iifayili zabo kwiindawo zasemaphandleni ukufikelela ngokuthe ngqo ngamakhaya. Abanikezeli kunye nabaqeqeshi bezoshishino baqhagamshelana nokufakwa kwezi "zokugqibela zokuhamba".
Ezinye iinkonzo ze-FTTH ezaziwa kangcono kwiimarike namhlanje ziquka iVerizon FIOS kunye ne-Google Fiber. Ezi nkonzo zinokunika i-gigabit (1 Gbps) kwiintanethi ngesivinini kwindlu nganye. Nangona kunjalo, nangona ababoneleli banikezela ngeendleko eziphantsi, ngokuqhelekileyo banika neephakheji zamandla ezincinci kumakhasimende abo.
- I-FTTP (iFiber kwi-Premises): I- Fiber ebeka yonke indlela ukuya kwisakhiwo.
- I-FTTB (iFiber kwiZakhiwo / iBusiness / Block): efanayo neFTTP.
- I-FTTC / N (iFiber kwi-Curb yeNode): I- Fiber ebeka kwi-node kodwa ke iingcingo zethusi zizalisa uxhumano ngaphakathi kwesakhiwo.
- I-fiber ngqo: I- Fiber eshiya i-ofisi ephakathi kwaye ifakwe ngqo kumthengi omnye. Oku kunika indawo enkulu kunazo zonke kodwa kuyabiza.
- Ifayibha eyabelwe: Ufana nefayibha yecandelo ngaphandle kokuba njengoko ifayibha ifinyelela kwisakhiwo sabathengi abasondeleyo, iyahlukana ibe yimibhobho yabanye kubasebenzisi.
Yintoni iFiber Fiber?
Ixesha elimnyama i-fibre (ngokuphindaphindiweyo i- fiber emnyama okanye ebizwa ngokuthi i- fiber evulekileyo ) ngokuqhelekileyo ibhekisela kwi-fiber optic cabling efakwe apha. Ngamanye amaxesha kubhekisela kwiinkqubo zefayili ezifakwe ngasese.
