PoE (Fais Fab Ntxiv Ethernet) hais txog qee tus IP-terminals (xws li IP tes, WLAN access points APs, network cameras) tsis muaj kev hloov rau Ethernet Cat.5 cabling infrastructure. Thaum kis tau cov ntaub ntawv, nws tseem tuaj yeem muab DC lub zog fais fab kev lag luam rau cov khoom siv. PoE tshuab tau ua kom lub lag luam ntawm cov lag luam uas tseem tshuav tam sim no kom txuag txoj kev ruaj ntseg ntawm cov qauv uas twb muaj lawm, thiab txo nqi. Tsuas yog muab, PoE (Hwjchim Hla Tebchaws Ethernet) yog ib hom DC hwjchim los ntawm lub network cable.
Ib daim ntawv sau ua pov thawj PoE muaj xws li ob ntu: Lub Chaw Siv Hluav Taws Xob (PSE) thiab ib qho Kev Siv Hluav Taws Xob (PD).
Cov Khoom Siv (Power Supply Equipment) (PSE): Ethernet keyboards, routers, hubs, lossis lwm yam khoom siv hloov xov xwm uas txhawb POE functionality
Txais kev ntaus ntawv (PD): Hauv kev kaw lus, nws yog lub koob yees duab network (IPC).
Yog li cov cable network uas zoo tshaj plaws rau PoE fais fab, lub network cable yuav tsum txuas nrog lub network cable raws li tus qauv ntawm 568A los yog 568B, thiab 8 xov tooj yuav tsum tau txuas rau hauv 100 meters. Qhov zoo ntawm lub network cable yog lawm zoo tshaj, thiab qhov kev hloov mus rau qhov chaw siab dua. Tsawg kawg nws yog qhov tsim nyog kom dhau Qeb 5 network cables. Yog hais tias tus nqi siv nyiaj txaus siab txaus, Qib 6 yuav tsum xaiv cov kev lag luam hauv Network, qhov kis tau tus mob kis mus ntxiv, thiab qhov tshwm sim zoo dua.
Qeb 6 kab: Kev sib kis ntawm hom kab no yog 1MHz ~ 250MHz. Qeb 6 qhov kev sib txuas lus yuav tsum muaj ib qho paj loj rau hauv qhov kev cuam tshuam los ntawm kev ua kom tiav (PS-ACR) ntawm 200MHz, uas yog muab ob qhov bandwidth ntawm Super Category 5. Kev kis tau ntawm Qeb 6 pawg ntawm kev sib kis tau ntau dua Pawg Hom Lus 5 thiab zoo tshaj plaws rau cov kev siv nrog kev sib kis cov nqi 1Gbps zoo dua. Ib qho tseem ceeb sib txawv ntawm Qib 6 thiab Qib 5 yog qhov uas nws ua rau kev ua tau zoo ntawm qhov kev txiav txim siab thiab kev poob qis. Rau ib lub cim tshiab ntawm kev sib tw rau high-speed network, zoo heev tuaj poob kev kawm tseem ceeb heev. Tus qauv txuas yooj yim raug tshem tawm hauv cov qauv ntawm cov qauv. Lub cabling txheem txais ib lub hnub qub topology. Qhov yuav tsum tau khiav deb yog: qhov ntev ntawm qhov txuas ntev yuav tsis pub tshaj 90 m, thiab qhov ntev ntev ntawm channel tsis pub tshaj 100 m.
Super Qib 5 Cable: Super Qib 5 muaj tsawg tus attenuation, tsawg crosstalk, thiab attenuation dua thiab crosstalk piv (ACR) thiab qhov sib piv ntawm lub suab paj nruag (Structural Return Loss), yuam kev me me, thiab kev ua tau zoo heev. Super Class 5 cable yog siv rau Gigabit Ethernet (1000 Mbps).
