Qhov Zoo Ntawm VDSL2
VDSL2 siv tib lub tshuab DMT modulation technology nrog ADSL 2+, tuaj yeem rov qab tau tshaj ntawm ADSL2, thiab ua haujlwm hauv 2.2 MHz band ntawm ADSL2 + technology, piv rau VDSL2 nws tuaj yeem ua haujlwm rau 17 MHz txawm 30 MHz band, faib ntau dua muck channel thiab qis, nyob nrug deb tshaj tuaj yeem ua rau kom muaj ntau dua bandwidth, yog li ADSL2 + siv technology feem ntau nyob rau hauv cov khoom DSMS, thiab VDSL2 tsim rau nrug luv FTTC sab nraum zoov cov khoom los yog FTTB txoj kev daws teeb meem.
Ib qho zoo dua ntxiv rau kev siv VDSL2 yog lub davhlau ya nyob twg. VDSL2 dav hlau nrog ADSL2 + davhlau ya nyob ntawm qhov tsos thiab kev siv tsis zoo sib txawv, cov neeg siv txuas mus siv kev sib txuas ntawm cov neeg siv xov tooj rau broadband, piv rau qhov fiber-rau-lub-tsev FTTH thaj ua haujlwm tsis hloov hloov tsev neeg txoj kab thiab dai, hais txog kev ruaj ntseg cuam tshuam ntawm laser rau tib neeg ob lub qhov muag. Thiab VDSL2 rov qab ua haujlwm tau zoo dua tuaj yeem thaum khoom kho khoom hloov khoom qub ADSL2 + dav dav dav tseem tuaj yeem siv txuas ntxiv, tuaj yeem lav tau txoj kev hloov mus. Terminal tswj yuav siv txuas ntxiv nrog rau tib yam nrog ADSL2 + kev cai tswj thiab kev tswj cov kev tswj, cov kev tswj hwm kev tswj hwm thiab kev ua haujlwm zoo tib yam. Nrog rau kev siv cov VDSL2 davhlau ya nyob twg, VDSL2 davhlau ya nyob twg yuav muaj nqe ntau qhov nqi, ntxiv txo cov nqi ntawm network creation.
