Qee cov neeg siv khoom nug, muaj POE hloov pauv ntawm lub khw uas lees tias muaj peev xwm xa tau 150 meters lossis txawm tias 250 meters, puas yog qhov tseeb lossis cuav?

Ua ntej tshaj plaws, peb yuav tsum nkag siab tias POE yog dab tsi.POE yog cov ntawv luv ntawm Lub Hwj Chim dhau Ethernet, uas txhais tau hais tias tsis muaj kev hloov pauv rau Ethernet Cat.5 cabling infrastructure uas twb muaj lawm, nws tuaj yeem siv rau qee qhov IP-raws li cov davhlau ya nyob twg (xws li IP xov tooj).Cov thev naus laus zis uas tuaj yeem muab DC lub zog rau cov khoom siv no thaum xa cov ntaub ntawv teeb liab, xws li wireless LAN nkag mus rau cov ntsiab lus, APs, thiab lub koob yees duab network, yog qhov hloov pauv uas txhawb nqa lub zog dhau Ethernet.

Tus txheej txheem Ethernet tau teev tseg tias qhov siab tshaj plaws kis tau tus mob yog 100 meters, thiab cov ntaub ntawv qeeb thiab pob ntawv poob yuav tshwm sim yog tias qhov kev ncua deb tshaj 100 meters.
Tab sis tsis yog txhua lub network cables txwv rau 100 meters.Hauv kev ua haujlwm tiag tiag, lub network cable kuj tseem tuaj yeem xa tawm tau zoo tshaj 100 meters, thiab qhov zoo tuaj yeem ncav cuag li 120 meters, uas yog, tsis muaj oxygen-dawb tooj liab Cat.5 network cable, lossis qeb 6 network cable.

Ntau lub tuam txhab PoE tam sim no tau tshaj tawm 150-meter, ntev-ntev, 250-meter fais fab mov, thiab txawm tias 500-meter kis tau tus mob POE keyboards.Tsis yog nws txhais tau tias qhov kev ncua deb ntawm tus qauv POE keyboards yog 100 meters, thiab nws yog qhov zoo tshaj plaws los tswj qhov kev ncua deb li ntawm 80 meters hauv kev siv tiag tiag.Dab tsi yog qhov teeb meem?

Peb txhua tus paub tias PoE fais fab mov nrug yog txiav txim siab los ntawm kev sib kis ntawm cov ntaub ntawv teeb liab.Cov hluav taws xob ntshiab tuaj yeem xa mus tau deb heev, tab sis qhov sib kis ntawm cov ntaub ntawv teeb liab yog txiav txim siab los ntawm lub network cable.Qhov kev ncua deb ntawm qhov zoo tib yam qeb 5 cable cov ntaub ntawv teeb liab yog hais txog 100 meters.Txhawm rau kom ntseeg tau qhov zoo ntawm kev tsim kho, nws feem ntau yog 80-90 meters.Thov nco ntsoov tias qhov kev sib kis deb ntawm no yog hais txog qhov siab tshaj plaws, xws li 100M.
Ntau lub tuam txhab tau cim tias qhov kev ncua deb ntawm lawv cov POE keyboards tuaj yeem ncav cuag 150 meters, tab sis hauv kev siv tiag tiag, yog tias cov POE zoo tib yam hloov pauv xav kom ua tiav qhov kev sib kis ntawm 150 meters, lawv muaj cov kev cai nruj ntawm qhov zoo ntawm lub network cable.Lawv yuav tsum siv ntau tshaj li qeb 6 cables, uas nce txawm li ntawd los, yog hais tias lub sab hauv Circuit Court ntawm lub POE hloov tau txais ib tug heev network switching nti thiab ib tug POE fais fab mov tswj nti, nws yog tsis yooj yim sua kom ncav cuag ib tug network ntawm 100M thiab kis tau tus mob. ntawm 150 meters, txawm hais tias siv lub tshuab hluav taws xob zoo.Nws yuav ua rau kom lub zog siv zog, tshaj qhov kev siv hluav taws xob ntawm PoE fais fab mov, thiab tsis ruaj khov, nrog cov pob ntawv loj heev, kev sib kis loj bandwidth thiab teeb liab attenuation, ua rau cov teeb liab tsis ruaj khov, kev laus ntawm PoE hloov khoom siv, thiab kev nyuaj rau kev txij nkawm tom ntej. .

Txawm tias qhov kev ua tau zoo POE hloov nrog 100M tag nrho cov khoom thauj thiab kev sib kis tau ruaj khov tuaj yeem ncav cuag 150 meters xwb.Qhov kev ncua deb ntawm 250 meters yog dab tsi?Qhov tseeb, muaj txoj hauv kev.Yog tias tus nqi raug txo mus rau 10M, uas yog, qhov kis tau tus mob bandwidth yog 10M, qhov sib kis tau zoo.Txuas mus rau 250 meters (nyob ntawm seb qhov zoo ntawm lub network cable), cov cuab yeej no tsis muab cov bandwidth siab.Lub bandwidth yog compressed los ntawm 100M mus rau 10M, uas tsis yooj yim rau kev sib kis ntawm cov duab siab-txhais saib xyuas.
Ntau lub tuam txhab, thaum txhawb nqa lawv cov khoom los txhawb 250-meter kis tau tus mob, tsis txhob hais txog qhov poob mus rau 10M bandwidth, thiab xav tias txhob txwm zais qhov bandwidth los ntawm cov neeg siv khoom.

Ntxiv mus, tsis yog txhua lub POE keyboards tau yooj yim xa 250 meters ntev npaum li qhov bandwidth txo mus rau 10M.Qhov no kuj nyob ntawm qhov zoo ntawm qhov hloov.Yog hais tias lub internal switching nti adaptability ntawm lub hloov yog tsis zoo heev thiab lub hwj chim nti tswj muaj peev xwm tsis muaj zog, txawm yog hais tias 10M raug yuam kis tau tus mob, kuj tsis tuaj yeem lav qhov ruaj khov kis tau tus mob ntawm 250 meters, txawm tias 150 meters tsis tuaj yeem ncav cuag.

Yog li, nyob rau hauv txoj kev xav, kom ua tiav kev sib kis ntawm 250 meters, nws yog ib qho tsim nyog yuav tsum tau txais kev tsim hluav taws xob siab rau POE, thiab POE lub zog nti tau txais cov khoom lag luam zoo-qib chips.Lub zog tswj module tuaj yeem ntse thiab paub txog IEEE802.3af / ntawm tus qauv, hloov kho lub zog, thiab siv 8 cores tib lub sijhawm.Cov cuab yeej siv hluav taws xob txawj ntse, kom ua tiav cov haujlwm zoo li no, siv cov khoom siv hluav taws xob built-in, qhov kom zoo dua ntawm kev siv cov khoom siv hluav taws xob tsim hluav taws xob yog tias nws tuaj yeem ua kom zoo dua cov qauv tsim, txiav ntsuas lub zog xav tau ntawm qhov kawg tau txais thiab cov xaim xaim hluav taws xob impedance thiab lwm yam tsis, uas yog soj ntsuam thiab xam los ntawm lub ntse hwj chim tswj module thiab muab qhia rau lub internal fais fab mov Circuit Court los kho cov linear voltage input kom phim lub hwj chim tsis siv neeg tso zis rau lub kawg-powered khoom.
