Vectoring yog qhov txuas ntxiv ntawm DSL thev naus laus zis uas ntiav kev sib koom tes ntawm kab teeb liab kom txo qis crosstalk qib txhawm rau txhim kho kev ua tau zooNws yog raws li lub tswv yim ntawm kev tshem tawm suab nrov: thev naus laus zis tsom xam suab nrov Cov xwm txheej ntawm cov kab tooj liab thiab tsim kom muaj lub suab nrov tshem tawm.
Vim li cas thiaj yuav tsum muaj vectoring nrog VDSL2?
Vectoring zoo heev txhim kho qhov kev ua tau zoo ntawm VDSL2 los ntawm kev siv lub cev txheej txheej teeb liab ua kom muaj kev tshem tawm ntawm crosstalk ntawm tag nrho cov kabuas xaus ntawm ib qho DSLAM.
Vectoring siv rau dab tsi?
Vectoring yog siv los tus neeg sib tham sib tham - teeb liab xau ntawm lub xov tooj sib tw xov tooj uas txwv tsis pub VDSL2 qhov kev ua haujlwm me ntsis- raws li tau piav qhia tam sim no. Ob tug yam ntxwv tseem ceeb ntawm lub voj voog hauv zos txwv qhov kev ua tau zoo ntawm cov neeg siv khoom digital (DSL) thev naus laus zis: teeb liab attenuation thiab crosstalk.
Vectoring hauv xov tooj yog dab tsi?
Vectoring yog a crosstalk-tso thev naus laus zis, uas yog lub teeb liab tawm ntawm theem ntawm kev kwv yees crosstalk yog siv rau txhua kab hauv ib kab, ua kom nws ploj mus. Qhov no tso cai rau txhua tus neeg txoj kab ua haujlwm ntawm qhov ua tau zoo tshaj plaws, tsis cuam tshuam los ntawm cov kab txuas los yog cov khoom sib txuas.
G INP ua haujlwm li cas?
G. INP tso cai rau ib tug fiber ntau broadband kab feem ntau sync siab dua tsis muaj G. INP txij li thaum nws muab lub mechanism rau retransmitting lub sij hawm poob cov ntaub ntawv pob ntawvyam tsis tas yuav txo qis kev sib txuas ceev los yog qhia interleaving.
