Fibre optic inthanethi - kuyini? Indlela kokuxhuma Inthanethi fiber-optic

Muva nje, abaningi kangaka balithanda internet fibre optic. Abanengi bayazi bona lobu buchwepheshe kuhilela ukudluliswa kwedatha ngesivinini kahle eliphezulu. Akunjalo kudala, njengezinye eziningi isivinini kwakubonakala fantasy, nakuba optical fibre ubuchwepheshe basungula pheze eminyakeni eyikhulu edlule - emuva namathathu banesifo esibi kwekhulu elidlule. Yingakho-ke kuhle ukucabangela ukuthi lokhu internet fibre optic futhi kungani lo mshini esingenakuqhathaniswa.

Umlando omncane

Umzamo lokuqala ngesikhathi ibanga ukudluliswa kwedatha izinto ukukhanya esobala zakhiqizwa 1934. Norman Frenchem wacelwa ukuba ukuguqula izwi ibe amaza ukukhanya, okuyinto ke izodluliselwa yi izinti ingilazi. Ngemva kweminyaka eminingana, physics baseSwitzerland Jean Daniel Colladon experiment owenziwa nge ukudluliselwa ukukhanya ngokusebenzisa "parabolic ukugeleza uketshezi", amanzi isb. fibre Optical injalo manje uvele 1954. Ubuqambi kungokwalabo zesayensi amabili besuka eNgilandi - UHarold Hopkins futhi Narinder Singh Kapany, kanye abacwaningi baseNetherlands - Abrahama Van Hilu. Njengoba ziyizidalwa ngesikhathi esifanayo yamemezela wakhe wokusungula, bobathathu waqala cabanga abasunguli ubuchwepheshe. Futhi ngemva kweminyaka emibili igama laqanjwa - fibre.

Ukulahlekelwa ukukhanya kusukela kuqala optical fibre izintambo bekukukhulu kakhulu. Esikhathini zamashumi amahlanu ngasekupheleni Kertins Lawrence wakwazi ukunciphisa kubo. Futhi uma ivulwa laser ubuchwepheshe fibre elinye ithuba khona ngo-1962.

manje Ungabuyela okwamanje. Kuleli qophelo fibre optic internet it libhekene eliphezulu ngokwedlulele idatha yokudlulisa amazinga. Lokhu akusona isimanga. Imininingwane yenkampani yenethiwekhi kulokhu ukukhanya, futhi ijubane layo uma igijima ezihambayo likhulu kunawo wonke endaweni yonke. Le mpahla liyadingeka kufanele isetshenzisiwe, futsi liBhayibheli linjalo. Ngomqondo lula, ikhodi kanambambili idluliselwa ngendlela elandelayo: uma ukukhanya ivuliwe ke lena, hhayi - bese 0. I fibre optic internet ikhebula okuhambisa kushintshana amaqanda nabathandekayo ngesilinganiso yokuthi nqunu iso akunakwenzeka ukubona. Ukushenxisa ishayela okuhambelana Lidlulisela iguqula yezinzwa ningene ekukhanyeni. A ekupheleni ikhebula yesibili ngokuvamile ibekwe umamukeli wenza i ephambene uguqule.

Fibre web libhekene speed eliphezulu kakhulu, futhi yini inzuzo yayo esemqoka. Enye inzuzo kungenziwa ngokuthi ikhono usebenze olude. Fiber-optic ikhebula ku-intanethi sisiba phezu ekujuleni kolwandle, ke kungaba sifinyelele kuka lonke izwekazi. Ngokwemvelo, Monterey, okuyinto badedele ke, siba nzima kakhulu: bona ulungise yokukhulisa umsindo isignali emalungeni, okuyizinto eziningana kayikhulu eqolo ngaphezu kwanoma wire ngokwayo, kodwa nobuchwepheshe bebonke, ukutshalwa kwezimali okunjalo akukwazi kubhekwe ngokweqile.

izakhiwo ezengeziwe

Transmission of ulwazi ngale ndlela isetshenziswa kwezinye izindawo. Ngokusebenzisa wiring kungenzeka ukunikeza ukukhanya ayetholakala phakathi nokuhlinzwa eziyinkimbinkimbi inhliziyo noma ubuchopho bomuntu. Kuyanda futhi uhlelo ukukhanya, esekelwe - zonke fibre efanayo optical, kuphela esikhundleni nolwazi ukulethe endlini wokukhanya kwelanga athwebula mgwaqo.

Ngaphezu isivinini kanye eside yokudlulisela ibanga kolwazi, kuyatholakala lobu buchwepheshe nomunye plus - ulwazi uma isetshenziswa nokunciphisa cishe akunakwenzeka.

Fibre optic inthanethi: amaphutha

Inkinga nansi kuphela eyodwa - imishini ezibizayo namathuluzi ukufakwa. Ikhebula ngokwayo kubiza akunjalo ezibizayo uma ziqhathaniswa Lidlulisela, umamukeli bese isignali yokukhulisa umsindo. Spike izintambo eyalo inverters ekhethekile, ezingasetshenziswa abiza izimoto kakhulu ezibizayo.

Fibre web libhekene ngesivinini, njengoba iye yachazwa ngaphambili. Ukusetshenziswa ekhaya, izinga layo obuncane 10 MB / s. Emzimbeni, akukho ikhebula ekhaya ayikwazi obusekela ngesivinini. Into efanele ukusebenzisa uxhumano esimweni iseva ekhaya, noma uma ungeyena omunye, kodwa amakhompyutha ambalwa ukuthi njalo badinga ukufinyelela i-Inthanethi. Zokwehlukanisa optical ukufakwa fibre ikhebula kudinga router ekhethekile. Kungaba ukusetshenziswa ekhaya noma isiteshi esikhulu. Fibre optic internet uzosebenzisana imizila ayisipesheli ekhishwe ngo-2010 noma kamuva. ububanzi wabo ngempela ebanzi, ngakho umsebenzisi ngamunye kungaba ukhethe best.

Fibre optic Inthanethi (Rostelecom)

Rostelecom inkampani akuyona onyakeni wokuqala inikeza izakhamuzi nge ukufinyelela World Wide Web usebenzisa ADSL ubuchwepheshe, okuhilela okuxhunyanwa isiginali phezu ejwayelekile yocingo umugqa. Manje opharetha uqalile ngenkuthalo ukwethula izindlela ezintsha ngokuphelele. Manje ngenkuthalo waqalisa ubuchwepheshe fibre optic Inthanethi FTTB (fibre isakhiwo). Nayo ungakwazi ukwenza ngcono izinga kwemisebenzi yomphakathi, nokwethenjelwa uxhumano nesivinini esiphezulu ezingaba afinyelela megabits 100 ngomzuzwana. Lapho kuyoba inethiwekhi ukuthatha Redesign okuphelele, ngamunye ohlala akhethiwe kwalesi sigodi uzokwazi ukusebenzisa uhla egcwele services. Ngokwesibonelo, uzokwazi ukubuka i-TV digital, okuyinto ngezinye izikhathi idlula ikhebula satellite izinga namakhono. isixazululo enjalo - high ividiyo, isithombe bese umsindo, kanye enembile, amamenyu interactive, lula ukusetshenziswa, kanye nezinye izinzuzo.

okutholakele

Kuleli qophelo fibre optic internet ikhambi ezintsha zezinkinga ukudluliswa kwedatha. Idlule ijubane layo uma igijima can kriptoseti kuphela, okuyizinto namanje at esigabeni design, engakabi esicacile lapho sizoqala ukuthuthukisa. Ngakho-ke kudingekile ukuba acabange ngendlela ukuxhuma internet fibre optic.
