Peb txhua tus paub hais tias DVI (Digital Visual Interface) yog lub computer qhov interface. DVI xa cov teeb meem digital. Piv nrog VGA cov teeb meem yav dhau los, DVI cov teeb liab muaj qhov zoo tshaj plaws, xws li ceev ceev ceev, tshem tawm ntawm tailing, tsis muaj teebmeem ntawm cov teeb liab, thiab duab meej. Txawm li cas los xij, nyob rau hauv cov kev kho mob tam sim no, DVI kuj muaj qhov tsis zoo, uas yog, qhov kev sib kis tau yog luv. Raws li ib txwm muaj, tus DVI cable tsuas muaj peev xwm tshaj tawm cov teeb meem txog 5 meters, thiab qhov teeb meem ntawm qhov teeb meem yuav tshwm sim yog tias nws tshaj 5 meters. Qhov kev lag luam no ua tau zoo tshaj plaws rau qhov chaw thiab daim ntawv thov DVI. Yog li ntawd, yuav ua li cas ntxiv ntev kis ntawm DVI tej teeb liab los ua ib qho teeb meem uas yuav tshwm sim. Tuam txhab uas muag ua haujlwm nyuab heev los nrhiav kev lag luam zoo tshaj plaws. Peb tau coj ntau txoj kev paub tab thiab muab kev qhia rau koj.
1. Siv DVI fiber optic cable tshwj xeeb
Tus kab DVI raug kab yog tus tub tooj tooj liab uas tsis tuaj yeem siv rau cov kev qhia ntev ntev. Qhov tshwj xeeb cable yog tsim los ntawm kev ntxiv fiber ntau rau lub hauv paus ntawm tus ntxhais tooj hlau thiab ua rau DVI fiber ntau cable. Cov kab no yuav raug xa mus txog 500 meters. Qhov siab tshaj plaws daws teeb meem 1920 x 1200. Qhov cable no muaj DVI connector rau ob sab rau kev txuas mus rau lub computer thiab cov duab. Zoo: Qhov zoo sib txuas yog qhov yooj yim thiab tsis xav kom muaj kev sib txuas mus los.
Tsis zoo: cov nqi cable siab, kab hluav taws xob loj, tsis haum rau qhov chaw nyob ntev, yog tias koj xav hnav ib lub raj, nws pom zoo kom siv lub siab-txhais tube DVI cable.
2. Siv cov teebmeem amplifiers thiab repeaters
Yog hais tias qhov kis tau tus mob yog 30 mais. Ib lub teeb meem thev naus laus los yog siv tau ua dua. Qhov sib txawv ntawm lawv yog tias qhov kev hloov rau lub vijtsam tso rau ntawm DVI cable kawg, thiab cov teebmeem ua kom nrov muaj kab ntsaws; qhov ntsuas tshaj tawm, raws li lub npe tawm, muab tso rau hauv nruab nrab ntawm ob qhov DVI cables rau kev tawm suab. Sib piv qhov kis tau tus mob thiab kev txhawb kev daws teeb meem thiab kev them nqi, ob yam khoom siv yeej zoo li qub, tab sis lawv raug xaiv raws li qhov xav tau ntawm cov neeg siv, yog li peb muab lawv rau tib pawg. Feem ntau teeb ceem amplifiers thiab repeaters tuaj yeem muaj peev xwm xa tawm 1920 x 1200 tawm xov xwm mus rau 15 mais, thiab xa 1280x1024 DVI ntsais teeb rau 30 meters, siv lub cev DVI. Ob qho cuab yeej siv yog tsim rau nruab nrab luv luv ntau kis. Qhov zoo: me, yooj yim, thiab raug nyiaj tsawg.
Disadvantages: Tsis haum rau kev ncua ntev kis.
3. Cov kis dua ib khub uas sib tw (CAT-5e)
Haum rau qhov nruab nrab cov kis tau tus mob, feem ntau 1290 x 1200 qhov kev xa tawm yuav kis tau 50 meters, thiab cov teeb meem tsis sib haum yuav raug xa mus ntev dua. DVI twisted tw transmitter nrog rau ib qho kev sib tshuam thiab ib tus neeg txais khoom, thiab qee cov chaw lag luam yuav tsum muab lus fais fab ntawm ob hnub.
Cov khoom siv hauv tsev tsuas yog siv tau los ntawm ib qho kawg. Thaum kis tau cov teeb liab hauv DVI, DDC cov teeb liab tseem xav tau los txheeb xyuas qhov kev daws teeb meem thiab lwm cov teeb meem. Yog li, lub transmitter thiab lub receiver feem ntau yog kev sib txuas los ntawm ob tug sib tw, thiab DVI cov teeb liab thiab DDC cov teeb liab yog qhov sib kis tau. Txawm hais tias DVI twisted tw transmitter muaj qee yam nqi, khub twisted yog tus nqi pheej yig thiab yooj yim rau lawv, thiab qhov kis tau tus mob yog ntev, uas txo tus nqi nruab nrab, yog li no txoj kev ua ib qho kev lees txais dav. Qhov zoo: tus nqi nruab nrab thiab yooj yim thaiv.
Disadvantages: Ob tug khoom siv, lub receiver thiab lub transmitter, ntxiv rau ntawm lub tshuab computer thiab cov duab, thiab qhov teeb meem yog qhov teeb meem.
4. Kev siv cov khoom siv fiber ntau fiber ntau yog tsim rau kev sib kis ntev, mus txog 500 meters.
Qhov no txawv ntawm thawj ib qho uas nws siv hom kab mob fiber ntau optic cable, LC multimode lossis ST cable, thaum thawj txoj kev siv cable tshwj xeeb. Nws ua haujlwm tau zoo ib yam li ib kab twisted transmitter, siv ib tug khub transmitters thiab receivers, kis DVI cov teeb tsa nrog fiber ntau optic cables, thiab xa DDC ntsais teeb nrog ib khub uas sib tw.
Zoo: kev kis ntev ntev
Disadvantages: Cov twj kho qhov muag pom tau yooj yim, txhuam yooj yim, thiab them nyiaj ntau dua thaum thaiv.
5. Txuas ob kab mob siab ntev DVI tooj liab (txog 80 meters)
Txoj kev no tuaj yeem ua raws li txoj kev kis mus rau sab hauv tsev uas yuav tsum tau muaj nyob rau hauv txoj haujlwm tam sim no. Ib qho tseem ceeb hauv kev xaiv qhov hom no yog xav kom DVI zoo tshaj qhov zoo tshaj plaws. Piv txwv li, ob kab 40-meter DVI cables los yog ob tug 40-meter engineering-qib HDMI cables los ntawm Rui HD tuaj yeem txuas nrog rau 80 mus rau theem.
Zoo: muaj nqi nruab nrab thiab muaj zog nyob ruaj khov.
Disadvantages: Muaj peev xwm kis tau mus txog 80 meters thiab qhov nyob deb li cas.
