Ikhebula le-fiber optic ikhebula lenethiwekhi eliqukethe izinsimbi zezingilazi zangilazi ngaphakathi kwesikhwama se-insulated. Zenzelwe ibanga elide, ukuxhumana kwedatha eliphezulu kakhulu, nokuxhumana.
Uma kuqhathaniswa namakhodi wired, amakhodi e-fiber optic ahlinzeka ngamanethiwekhi angaphezulu futhi angadlulisa idatha kudlula amabanga amade.
Amakhodi e-Fiber optic asekela iningi le-intanethi yezwe, ithelevishini ye-cable neyefoni.
Indlela Ama-Fiber Optic Cables asebenza ngayo
Ama-fiber optic amakhodi athatha izimpawu zokuxhumana usebenzisa izimpande zokukhanya ezikhiqizwa ngama-lasers amancane noma ama-diode akhanyayo (ama-LED).
Ikhebula liqukethe ingilazi eyodwa noma ngaphezulu, ngayinye elula kakhulu kunezinwele zomuntu. I-center ye-strand ngayinye ibizwa ngokuthi iyinhloko, enikeza indlela yokukhanya ukuhamba. Umgogodla ugozwe ngendwangu yeglasi ebizwa ngokuthi ukugqoka ekhombisa ukukhanya kwangaphakathi ukuze ugweme ukulahlekelwa kwesignali futhi uvumele ukukhanya kudlule ukugoba kwekhebula.
Izinhlobo ezimbili eziyinhloko zezintambo zezintambo zibizwa Imodi eyodwa kanye ne- multi-mode fiber. I-mode yefayibha yodwa isebenzisa ingilazi yesikhumba esincane kakhulu futhi i-laser yokukhiqiza ukukhanya kuyilapho izintambo eziningi ze-mode zisebenzisa ama-LED.
Ama-mode fiber amanethiwekhi amanethiwekhi avame ukusebenzisa amasu we- Wave Division Multiplexing (WDM) ukuze ukwandise inani lomgwaqo wedatha ongathunyelwa ngaphesheya kwe-strand. I-WDM ivumela ukukhanya emajukwini amaningi ahlukahlukene okumele ahlanganiswe (multiplexed) futhi ahlukaniswe kamuva (de-multiplexed), ngokuphumelelayo adlulise imifudlana eminingi yokuxhumana nge-pulse eyodwa yokukhanya.
Izinzuzo zamaCiber Fiber Optic
Ama-fibre amakhodi anikeza izinzuzo eziningana ngaphezu kwekamelo lokubamba lendabuko elide elide.
- I-fibre optics inamandla angaphezulu. Inani le-bandwidth yenethiwekhi ikhebula le-fiber lingathwala kalula lidlula ikhebula lesethusi elinomzimba ofanayo. Ama-fibre amakhodi alinganiswe ku-10 Gbps, ama-40 Gbps kanye nama-100 Gbps ajwayelekile.
- Njengoba ukukhanya kungakwazi ukuhamba amabanga amade kakhulu phansi kwebhedi yefayibha ngaphandle kokulahlekelwa amandla ayo, kunciphisa isidingo sezinkomba zesignali.
- I-fibre ayikwazi ukuphazamiseka. Ikhebuli lezintambo zendabuko idinga ukuvikelwa okhethekile ukuyivikela ekuphazamiseni kwe-electromagnetic. Ngenkathi lokhu kuvikela kukusiza, akwanele ukuvimbela ukuphazanyiswa lapho izintambo eziningi zihlanganiswa ndawonye eduze komunye nomunye. Izinto ezibonakalayo zengilazi kanye ne-fiber cables zigwema okuningi kulezi zinkinga.
I-Fiber Ekhaya (i-FTTH), Okunye Okusebenzayo, nama-Fiber Networks
Nakuba izintambo eziningi zifakiwe ukusekela ukuxhumana okude emadolobheni nakwamanye amazwe, abahlinzeki be-intanethi abathile bendawo bafaka imali ekukhuliseni ukufakwa kwezifayibha zabo ezindaweni zasemadolobheni ukuthola ukufinyelela ngqo kwemindeni. Abanikezeli kanye nabachwepheshe bemboni babiza lezi zikhungo "zokugcina amayela".
Amanye amasevisi e-FTTH awaziwa kakhulu emakethe namuhla afaka i-Verizon FIOS ne-Google Fiber. Lezi zinsizakalo zinganikeza isivinini se-gigabit (1 Gbps) kwi-intanethi ngayinye ekhaya. Kodwa-ke, nakuba abahlinzeki banikeza nezindleko eziphansi, ngokuvamile bahlinzeke ngamaphakheji amandla amancane kumakhasimende abo.
- I-FTTP (I-Fiber kuya Izakhiwo): I- Fiber ebeka yonke indlela kuze kube sesakhiweni.
- I-FTTB (I-Fiber ku-Building / Ibhizinisi / i-Block): Ifana ne-FTTP.
- I-FTTC / N (I-fibre kuya ku-Curb of Node): I- fibre ebeka kwi-node kodwa izingcingo zethusi ziqedela uxhumano ngaphakathi kwesakhiwo.
- I-fiber ngqo: I- fibre ephuma ehhovisi eliphakathi futhi ifakwe ngqo kumakhasimende owodwa. Lokhu kunikeza umkhawulokudonsa omkhulu kunabo bonke kodwa obiza kakhulu.
- I-fiber eyabelane: Okufana ne-fiber eqondile ngaphandle kokuthi njengoba i-fiber isondela eduze kwendawo yamakhasimende aseduzane, ihlukaniswa zibe ezinye izintambo zabasebenzisi.
Iyini iFiber Fiber?
I-term fiber emnyama (ngokuvamile i- fiber emnyama ebizwa ngokuthi i- fiber noma ebizwa ngokuthi i- fiber engenayo ) ngokuvamile ivame ukubhekwa kwekhamera ye-fiber optic engasetshenziswa njengamanje. Ngezinye izikhathi futhi libhekisela ekufakweni kwefayibha eqhutshwa ngasese.
