Technology GPON - jahooyinka cusub ee isgaarsiinta

The-technology GPON haatan ugu casri ah, hufan oo mustaqbalka eegaya in qoyska si cadaalad ballaaran oo shabakadaha fiber-optic dadban. Iyada oo ku saleysan ee hadda ku sannadihii la soo dhaafay, heerarka Yurub, waxa uu siiyaa ka shaqeeya TV-cable iyo bixiyeyaasha adeegga Internet in ay xal wax ku ool ah oo duurka ku ah helitaanka-xawaaraha sare ee ay u World Wide Web ah, signal deggan iyo tayada gaar ah ee images television. GPON-technology sidoo kale waxay bixisaa kaydka aad u muhiim ah oo fiber ah indhaha iyada oo geed topology a naqshadaha network, iyo isku halaynta sare waxaa lagu gaarayaa by xubno branching dadban. Laakiin laga yaabaa in faa'iido ugu weyn ee tabo cusub isgaarsiinta waa a-xawaaraha sare "mile ee la soo dhaafay".

GPON-technology taageertaa farsamada casriga ah ee multiplexing qeybinta Milanello, kaas oo u ogolaanaya in ay si weyn u kordhiyo awoodda network aan casriyeeyo kaabayaasha cable ay. topology geed A waxay bixiyaan fursado weyn oo loogu talagalay adeegyada macmiilka bandwidth maamulka dabacsan. At technology isla GPON leeyahay heerka ku filan sare xogta bixiya hufnaan gaadiidka kala duwan ee adeegyada: SDH, Ethernet, ATM, iwm

Sayidka, faa'iidooyinka badan oo ka mid ah shabakadaha fiber-optic dadban iyo tiro ka mid ah sifooyinka gaarka ah waxaa go'aamiya faa'iidooyinka of technology this ka badan naqshadaba kale isgaarsiinta, gaar ahaan xagga-xawaaraha sare "mile ee la soo dhaafay". Tan waxa u sabab faafidda deg deg ah ee cusub ee dhismaha-xawaaraha sare ee shabakadaha multiservice magaalada fiber-optic. Waa maxay-GPON technology, iyo waxa ay nuxurka?

keligeed, waa fudud, sida oo dhan cajiib ah. The Guntin bixiyaha dhexe, bixinta dhibcood-xawaaraha sare ee la xidhiidha laf ku xiran shabakadda dadban indhaha macmiilka ee naqshadaha geed. Tani waxay abuurtaa a qanjidhada gaar ah dhexe in martigalinta splitters dadban is haysta (splitters) nooca indhaha. Ay caajisnimo ka dhigan tahay in ay gabi ahaanba uma baahna cunto ama adeeg.

GPON-qalabka, splitters, waxaa ka mid ah adeegga multi hardware iyo madal saldhigga software iyo user boosteejada. Oo mid madal gudbin kartaa macluumaad tiro ka mid ah qalabka macmiilka, kaas oo kuu ogolaanaya in aad si aad u xirmaan awoodda miisaaniyadda iyo transceiver xawaaraha hardware. Iskudarka qalabka casriga ah kuu ogolaanayaa inaad si dhakhso ah oo kharash-ool ah la geeyo network fiber-optic dadban, iyo tayeynta naqshadaha cable ka.

Waa xiiso leh waxa weeye in shabakadaha fiber indhaha dadban aan wax ka mid ah hababka maalinta la joogo. horumarinta technology gudbinta this bilaabay in tiris ah, in guntiisa shaybaar Telecom British. A dhowr sano ka dib ka tijaabooyin baaritaan ugu horeysay lagu fuliyay kadib markii bilowga horumarinta, kuwaas oo goob joog ka ahaa TV-ga si fiican u yaqaan European badan. In mustaqbalka, technology this ayaa maray marxalado badan oo horumar iyo casriyeynta. Shabakadda horeysay dadban ee noocan lahaa awoodda of 155 Mbit / s. Si kastaba ha ahaatee, waqtiga this ahaa ku filan. Oo haatan kaliya, ay sabab u tahay horumarka degdeg ah oo ka mid ah Internet iyo telefishinka dijital ah, technology waxaa cadaatay in ay aad u caan ah.
