Iindidi zokumodareyitha, iinguqulelo zayo kunye namanqanaba ophuhliso kwi-ADSL nakwi-VDSL

Uxolo, inceba kunye neentsikelelo zikaThixo,

Wanga uThixo angakusikelela ngako konke okubalaseleyo, abalandeli abathandekayo, ndiyathemba ukuba usempilweni kwaye ukwimeko entle.

Ndingathanda ukuthetha nawe namhlanje malunga nokukhutshwa kwe Umgca wobhaliso wedijithali yintoni eyaziwayo phakathi kwethu ( DSL ) kunye nesantya esele sikhona,

Kananjalo malunga neenguqulelo ze Umgca ophezulu kakhulu wobhaliso lwedijithali okanye kwaziwa nini phakathi kwethu ( I-VDSL ) kunye nesantya sayo esele sikhona.

Itekhnoloji yokuqala eyaziwa ngokuba yi-ADSL

Sisishunqulelo se. Umgca wobhaliso weDijithali yeAsymmetric

 Isebenzisa imigangatho emithathu okanye iziseko, ezilandelayo:

I-ANSI T1.413 Inqaku 2

ITU G.992.1 >> Yaziwa njenge G.DMT Ixhasa isantya sokukhuphela iifayile kwii-megabytes eziyi-8 kwaye ulayishe iifayile kwi-megabyte e-1
ITU G.992.2 >> Kukwaziwa njenge G.LITE Ixhasa isantya sokukhuphela iifayile kwii-megabytes eziyi-2 kwaye ulayishe iifayile kwi-megabyte e-2

Emva koko, kwaphuhliswa ADSL kum

I-ADSL 2

Kusetyenziswe imigangatho okanye iziseko ezi-4, ezi zilandelayo

ITU G.992.3 >> Kukwaziwa njenge Iibhski ze-DMD Ixhasa isantya sokukhuphela iifayile kwii-megabytes ezili-12 kwaye ulayishe iifayile kwii-megabytes ezi-3, kuxhomekeke kuhlobo kunye nohlobo lwefayile KwisiHlomelo ..

ITU G.992.4 >> Kukwaziwa njenge G. lite. bis Ixhasa isantya sokukhuphela iifayile kwi-megabytes ezi-1 ezinesiqingatha, kunye nesantya sokulayisha iifayile ziye kuma-512.

ITU G.992.3 Isihlomelo J >> Uhlobo lweemodeli kodwa luxhomekeke kuhlobo lwe
Isihlomelo j Ivumela ukukhula kwesantya sokulayisha kwifayile ukusuka kwi-1 megabyte ukuya kwi-4 megabytes.

I-ITU G.992.3 Isihlomelo L >> Sikwabizwa ngokuba yi-READSL2, okt ukufikelela kwi-adsl2 eyandisiweyo kwaye isetyenziselwa imigama emide enokufikelela kwi-7 km, ekwabizwa ngokuba yi-RAM okanye indlela yokuguqula imeko .. Ixhasa isantya sokukhuphela ukusuka kwi-800 KB ukuya kwi-2 MB kunye layisha isantya ukusuka kwi-128 KB ukuya kwi-200 KB.

Emva koko, kwaphuhliswa I-ADSL2 kum

Ukudibanisa i-ADSL2 okanye ADSL2 +

Ngokwenyani isebenzisa iinguqulelo ezininzi zemodeli yemigangatho, kodwa siza kukhankanya uhlobo oluthile kuphela, olulandelayo:

I-ITU G.992.5 >> Ixhasa isantya sokukhuphela kwii-megabytes ezingama-24 kunye nesantya sokulayisha ukuya kuthi ga kwi-2 megabytes ..

Emva koko kwafika iteknoloji eyaziwa ngokuba

I-VDSL okanye VHDSL

Sisishunqulelo se. Umgangatho ophezulu kakhulu wokurhuma kwidijithali Isebenzisa uhlobo olunye kuphela lwemodeli esemgangathweni, elandelayo:

I-ITU G.993.1 >> Ixhasa isantya sokukhuphela kwii-megabyte ezingama-52 kunye nesantya sokulayisha kwii-megabytes eziyi-16 (kusetyenziswa intambo yobhedu eyaziwayo esinayo) kwaye sisebenzisa intambo coaxial Isantya sokukhuphela zii-megabytes ezingama-85 kwaye isantya sokulayisha zii-megabytes ezingama-85.

Lo ngumfanekiso wentambo coaxial

Emva koko, kwaphuhliswa I-VDSL kum

VDSL2

Isebenzisa uhlobo olunye kuphela lwemodeli esemgangathweni kwaye ixhomekeke kuhlobo lwe I-FTTX kwaye yena I-FTTC okanye into ayaziyo Ifayibha kwiKhabhinethi Oko kukuthi, imicu ye-optical eyolulela kwi-sub-cabin eyaziwayo kwaye bayondliwa ngale teknoloji

I-ITU G.993.2 >> >> Ixhasa isantya esifikelela kwi-megabyte ezingama-200, isantya sokukhuphela ngokuxhomekeke kumgama womntu ukusuka kwi-sub-cabin ebumelwaneni, hayi eyona ndawo iphambili, ejongene ADSL ..

Kwaye ungalibali ukuba konke oku kungasentla kuyachaphazeleka ngumgama phakathi komgca womsebenzisi kunye nekhabhathi, nokuba ingaphantsi okanye iphambili ..

Umxholo onxulumene noko

Wazi ntoni malunga ne-FTTH

Ndiyathemba ukuba ndiphumelele ekuhambiseni nasekucaciseni obu buchule.

Oku kwaye uThixo wazi ngcono kwaye uphezulu

Uyisebenzisa kanjani i-VDSL kwi-router

Ulujonga njani uhlobo lwe-DSL Modulation TE-Datha (ZXHNH108N)

Ulujonga njani uhlobo lwe-DSL Modulation TE-Datha (HG532)

Ulujonga njani uhlobo lwe-DSL Modulation TE-Datha (HG630 V2)
