Izinhlobo zokushintshashintsha kwezwi, izinhlobo zalo nezigaba zentuthuko ku-ADSL naku-VDSL

Ukuthula, isihe nezibusiso zikaNkulunkulu,

Kwangathi uNkulunkulu angakubusisa ngakho konke okuhle, abalandeli abathandekayo, ngiyethemba unempilo enhle futhi usesimweni esihle kakhulu.

Ngingathanda ukukhuluma nawe namuhla mayelana nokukhishwa kwe- umugqa wobhalisile wedijithali noma yini eyaziwa phakathi kwethu njengo ( DSL ) kanye nesivinini sayo esivele sikhona,

Futhi mayelana nezinguqulo ze- Ulayini omkhulu kakhulu wobhalisile wedijithali noma yini eyaziwa phakathi kwethu njengo ( I-VDSL ) kanye nesivinini sayo esikhona futhi.

Ubuchwepheshe bokuqala obaziwa nge-ADSL

Kuyisifinyezo se. Umugqa Wababhalisile we-Asymmetric Digital

 Isebenzisa amazinga amathathu noma ayisisekelo, okulandelayo:

I-ANSI T1.413 Ukukhishwa 2

I-ITU G.992.1 >> Eyaziwa njenge G.DMT Ixhasa isivinini sokulanda amafayela kuma-megabyte ayi-8 nokulayisha amafayela ku-1 megabyte
I-ITU G.992.2 >> Eyaziwa nangokuthi i- G.LITE Ixhasa isivinini sokulanda amafayela kuma-megabyte ayi-2 nokulayisha amafayela ku-2 megabyte

Ngemuva kwalokho, i-. Yathuthukiswa ADSL kimi

I-ADSL 2

Kusetshenziswa amazinga noma izisekelo ezi-4, okulandelayo

I-ITU G.992.3 >> Eyaziwa nangokuthi i- G.DMT.ibhayisikili Ixhasa isivinini sokulanda amafayela kuma-megabyte ayi-12 nokulayisha amafayela kuma-megabytes ama-3, kuya ngohlobo nohlobo lwefayela Isihlanganisi ..

I-ITU G.992.4 >> Eyaziwa nangokuthi i- I-G.lite.bis Ixhasa isivinini sokulanda amafayela cishe kuma-megabytes ayi-1 nohhafu, nejubane lokulayisha amafayela cishe kuma-512.

I-ITU G.992.3 Annex J >> Uhlobo lwemodeli kepha kuya ngohlobo lwe
isijobelelo j Ivumela ukwakhiwa kwejubane lokulayisha ifayela kusuka ku-1 megabyte kuye kuma-megabytes ama-4.

I-ITU G.992.3 Annex L L >> Ebizwa nangokuthi i-READSL2, okusho ukufinyelela kwi-adsl2 enwetshiwe futhi isetshenziselwa amabanga amade angafika ku-7 km. Yaziwa nangokuthi yi-RAM noma i-rate adaptive mode .. Ixhasa isivinini sokulanda esisuka ku-800 KB kuye cishe ku-2 MB futhi ulayishe ijubane Kusuka ku-128 KB kuye cishe ku-200 KB.

Ngemuva kwalokho, i-. Yathuthukiswa I-ADSL2 kimi

I-ADSL2 plus أو ADSL2 +

Empeleni isebenzisa izinhlobo eziningi zemodeli yamazinga, kepha sizokhuluma ngohlobo oluthile kuphela, okulandelayo:

I-ITU G.992.5 >> Ixhasa isivinini sokulanda sibe ngamamegabhayithi angama-24 futhi ilayishe isivinini cishe kuma-megabytes ama-2 ..

Bese kulandela ubuchwepheshe obaziwa ngokuthi

I-VDSL أو I-VHDSL

Kuyisifinyezo se. umugqa wobhaliso ophakeme kakhulu webhithi Isebenzisa uhlobo olulodwa kuphela lwemodeli ejwayelekile, okulandelayo:

I-ITU G.993.1 >> Ixhasa isivinini sokulanda siye kuma-52 Mbps futhi ilayishe isivinini siye kuma-Mbps ayi-16 (kusetshenziswa ikhebula lethusi elaziwayo) nangokusebenzisa i-ITU G.XNUMX coaxial Isivinini sokulanda ama-megabytes angama-85, kanti isivinini sokulayisha ngama-megabytes ayi-85.

Lesi isithombe sekhebula coaxial

Ngemuva kwalokho, i-. Yathuthukiswa I-VDSL kimi

I-VDSL2

Isebenzisa uhlobo olulodwa kuphela lwemodeli ejwayelekile futhi kuya ngohlobo lwe I-FTTX futhi yena I-FTTC noma akwaziyo I-Fibre KuKhabhinethi Lokho wukuthi, imicu ye-optical enwebela ekamelweni lethu elincane elaziwayo futhi ifakwa ngalobu buchwepheshe

I-ITU G.993.2 >> Ixhasa isivinini esifinyelela kuma-megabyte angama-200, isivinini sokulanda ngokuya ngebanga lomuntu kusuka ekamelweni elingaphansi komakhelwane hhayi idokodo elikhulu, elibhekene ADSL ..

Futhi ungakhohlwa ukuthi konke okungenhla kuthintwa ibanga eliphakathi kolayini womsebenzisi negumbi, noma ngabe lincane noma liyinhloko ..

Okuqukethwe okuhlobene

Yini oyaziyo nge-FTTH

Ngiyethemba ukuthi ngiphumelele ekudluliseni nasekucaciseni le ndlela.

Lokhu noNkulunkulu kwazi kakhulu futhi kuphakeme kakhulu

Ungayisebenzisa kanjani i-VDSL ku-router

Ungahlola kanjani uhlobo lwe-DSL Modulation TE-Data (ZXHNH108N)

Ungahlola kanjani uhlobo lwe-DSL Modulation TE-Data (HG532)

Ungahlola kanjani uhlobo lwe-DSL Modulation TE-Data (HG630 V2)
