I-Intanethi ye-Fiber-optic - yintoni na? Indlela yokudibanisa i-intanethi ye-fiber optic

Kungekudala, abaninzi abantu banomdla kwi-intanethi ye-fiber optic. Abaninzi bayazi ukuba le teknoloji ibandakanya ukudluliswa kwedatha kwisantya esiphezulu. Kungekude kudlulileyo, isantya esinjalo sasibonakala kunamaphupho amaninzi, nangona iteknoloji ye-fiber optical yaqala ukukhula malunga nekhulu leminyaka edlulileyo-kwi-thirties yenkulungwane edlulileyo. Yingakho kubalulekile ukuqwalasela i-Intanethi ye-fiber-optic kwaye kutheni le teknoloji ingekho kukhuphiswano.

Inxalenye ethile yembali

Okokuqala ukuzama ukuhambisa idatha kude kusetyenziswe izinto ezikhanyayo kunye nezibonakaliso zenziwa ngo-1934. U-Norman uFransi wacelwa ukuba aguqule ilizwi kwiimpawu ezikhanyayo, eziza kuhanjiswa kunye neentonga zeglasi. Kwiminyaka embalwa kamva isazi sefilosofi saseSwitzerland, uJean Daniel Colladon, senze uvavanyo lokukhanya ngokuguqulela "ngokusasaza kwamanzi", oko kukuthi, amanzi. Ifayibha yokusebenza kwifom yangomhla yabonakala ngo-1954. Ubunobumba bee-physicists ezimbini ezivela eNgilani - uHarold Hopkins noNarinder Singh Kapani, kunye nomphandi ovela eHolland-Abraham Van Hilu. Ekubeni baxela ngokukodwa okokuqala, bonke abathathu baqala ukuthathwa njengabaqambi beli teknoloji. Kwaye emva kweminyaka emibini, igama le-fiber laqalwa.

Ukulahleka kokukhanya ukusuka kwiintambo zokuqala zokukhanya kwakukhulu kakhulu. Ekupheleni kweminyaka yamahlanu, uLawrence Curtins wakwazi ukunciphisa. Yaye, xa ngo-1962, i-laser teknoloji yafunyanwa, i-fiber optics yafumana elinye ithuba lokuba khona.

Izixhobo

Ngoku ungabuyela okwangoku. Okwangoku, i-intanethi ye-fiber-optic ibonakala ngezinga eliphezulu lokudlulisa idatha. Oku akumangalisi neze. Umncedisi wolwazi kulolu hlobo ulula, kwaye isivini sawo sokuhamba sisona siphezulu kwindalo yonke. Le ndawo kufuneka ifumane isicelo, kwaye kunjalo. Ngomqondo olula, ikhowudi yebhinari idluliselwa ngale ndlela: ukuba ukukhanya kuvuliwe, ngulo-1, kwaye akukho-ke 0. Ikhefu le-intanethi ye-fiber ihambisa enye i-zeros kunye nayo kwijubane enokuthi ayikwazi ukuyibona ngeaso iso. Utshintsho lwamapulsi luxanduva lomthumeli, oluguqula iimpawu zombane kwiimpawu ezikhanyayo. Kwaye kwiphepha lesibini lekhebula, i-receiver ihlala ikhona, eyenza utshintsho oluguqukayo.

I-Intanethi ye-Fiber-optic ibonakaliswe ngesivinini esikhulu, eyona nto inenzuzo enkulu. Enye inzuzo kukukwazi ukusebenza kumgama omde. Ikhebula le-Fiber-optic ye -intanethi libekwe phantsi kwe-elwandle, inokuyolulela kulo lonke ilizwekazi. Ngokwemvelo, abakhi abakhayo banzima kakhulu: bafaka ama-amplifiers emigulini, axabisa amawaka angaphezu kwamaxesha angaphezu kwesawo, kodwa ezobuchwephesha ngokubanzi, utyalo-mali alukwazi ukubizwa ngokuba lukhulu kakhulu.

Iimpahla ezongezelelweyo

Ukuhanjiswa kolwazi ngale ndlela kusetyenziswa kwezinye iindawo. Ngokusebenzisa ucingo olugqibeleleyo, unokwenza ubuyekeze ngexesha lokusebenza kwintsebenzo entliziyweni okanye kwingqondo yomntu. Iinkqubo zokukhanya, ezisekelwe kwi-fiber efanayo, zifumana ukuthandwa, kodwa endaweni yengcaciso zizisa ilanga endlwini, ebanjwe esitalatweni.

Ukongeza kwisantya kunye nobude obude bokudluliswa kolwazi, kukho ubuchwepheshe obufanayo kunye nolunye udibaniso-akunakwenzeka ukuba unqamle idatha ngokuyisebenzisa.

I-Intanethi ye-Fiber-optic: ukungonakali

I-Minus inye kuphela-izixhobo ezibiza kakhulu kunye nezixhobo zokufakela. Ikhebula ngokwayo ayibizi kakhulu xa kuthelekiswa nabathumeli, abamkeli kunye nama-amplifiers. I-spike yocingo iqhutyelwa ngeendlela ezikhethekileyo, ezinokubiza njengeemoto ezibiza kakhulu.

Impawu

I-Intanethi ye-Fiber-optic ibonakala ngesantya esiphezulu, njengoko sele sichazwe ngaphambili. Ukusetyenziswa kwekhaya, ubuncinane bayo bunani li-10 MB / s. Ngokwemvelo, akukho ikhebula lekhaya elikwazi ukuxhasa eso santya. Kungcono ukusebenzisa olu xhumo ukuba unayo iseva yendlu, okanye ukuba unayo enye, kodwa iikhomputha ezininzi ezihlala zifuna ukufikelela kwi-intanethi. Ukuhlukanisa ikhebula le-fiber optic, kufuneka i router ekhethekileyo. Ingenziwa yenzelwe ukusetyenziswa kwekhaya okanye iziteshi zeetrunk. I-Intanethi ye-Fiber-optic iya kusebenza kunye neer routers ezikhethekileyo, ezikhishwe zingaphaya kwe-2010. Uluhlu lwabo lukhulu kakhulu, ngokokuba ngamnye umsebenzisi unokukhetha ukhetho olungcono.

I-Fiber optic Internet (Rostelecom)

I-Rostelecom ibonelela abantu ukuba bakwazi ukufikelela kwiWebhusayithi yeWebhsayithi kwiminyaka emininzi besebenzisa ubuchwepheshe be-ADSL, okubandakanya ukuthumela isigxina kumgca wefowuni rhoqo. Ngoku umqhubi uqalise ukuzisa ngokutsha iindlela ezintsha ezintsha. Ngoku i-intanethi ye-fiber optic isetyenziswe ngokusetyenziswa kweteknoloji yeFTTB (i-optics ukuya kwisakhiwo). Ngoncedo lwayo, unokuphucula kakhulu umgangatho weenkonzo ezinikezelwe kubemi, ukunyaniseka kokuxhamla kunye nesantya esiphezulu, esinokufikelela kuma-megabits angama-100 ngesibini. Xa inethwekhi iphuculwe ngokugcwele, ngamnye ohlala kwindawo yokuhlala ekhethiweyo uya kuba nako ukusebenzisa uhla lweenkonzo. Umzekelo, kuya kuba nethuba lokubukela ithelevishini yedijithali, ngamanye amaxesha idlula i-cable kunye ne-satellite quality kunye namakhono. Isisombululo esifanayo kukuba umgangatho ophezulu wezinto eziphathekayo zevidiyo, imifanekiso kunye nesandi, kunye nemenyu esebenzayo yokuzonwabisa, ukulungiswa kokusetyenziswa kunye nezinye izibonelelo.

Izigqibo

Okwangoku, i-intanethi ye-fiber-optic yisisombululo esiphambili kwingxaki yokudluliselwa kwedatha. Kuphela i-cryptosystems ezikwinqanaba lokuyila ziyakwazi ukunqumla kwisantya, kwaye ayikacaci xa uphuhliso lwabo luya kuqala. Kungoko kukufanelekile ukuqwalasela indlela yokudibanisa i-intanethi ye-fiber optic.
