Passive Poe Injector

Nyob rau hauv lub cheeb tsam ntawm lub network infrastructure, Lub hwj chim dhau Ethernet (PoE) thev naus laus zis tau hloov pauv li cas cov cuab yeej siv hluav taws xob thiab kev sib txuas, tshem tawm qhov xav tau ntawm cov hluav taws xob sib cais thiab ua kom yooj yim rau kev teeb tsa hauv ntau qhov chaw. Qhov no 8-chaw nres nkoj tsis yog- tus qauv passive PoE injector stands raws li ib tug txhim khu kev qha tshuaj rau xa hwj chim thiab cov ntaub ntawv los ntawm ib tug tib Ethernet cable. Tsim los rau kev ua tau zoo, nws txhawb nqa ob qho tib si PoE thiab cov khoom siv tsis yog PoE, ua rau nws yog ib qho tseem ceeb rau kev nthuav dav network peev xwm yam tsis muaj teeb meem nyuaj.

Cov tshuaj no siv tau nrog IEEE802.3af / ntawm cov khoom siv hauv network, tab sis nws ua haujlwm nyob rau hauv hom passive yam tsis muaj pib- kuaj pom. Thaum lub cuab yeej txuas nrog, nws muab lub zog ncaj qha, uas yuav tsum tau siv lub tshuab hluav taws xob lossis PoE splitter kom ua raws li IEEE 802.3af / ntawm cov qauv. Qhov tseem ceeb, cov khoom siv txuas nrog yuav tsum txhawb nqa lub zog nruab nrab ntawm tus pins: 4/5(+) thiab 7/8({10}}). Txoj hauv kev ncaj nraim no ua kom muaj kev sib koom ua ke tsis sib haum xeeb hauv ib puag ncig uas qhov kev xa hluav taws xob zoo ib yam yog qhov tseem ceeb.

Qhov tseem ceeb rau nws txoj kev ua haujlwm yog qhov sib npaug ntawm lub zog: Lub zog tawm tswv yim=Lub zog tso zis * Channels. Piv txwv li, nrog rau cov qauv zoo sib xws 4-chaw nres nkoj, DC48V 4A cov tswv yim tuaj yeem tawm DC12V 1A rau ib channel, lossis DC48V 2A cov tswv yim yuav muab DC48V 0.5A rau ib channel. Kev kho kom tsawg dua, xws li siv 3 tawm ntawm 4 nkaus xwb, DC12V 3A cov tswv yim tuaj yeem xa DC12V 1A rau ib channel. Ib txwm xaiv raws li koj lub cuab yeej siv hluav taws xob kom muaj kev ruaj ntseg-tag nrho cov kev siv yuav tsum nyob qis dua qhov khoom muaj peev xwm.

Qhov zoo tshaj plaws rau IEEE802.3af/ntawm cov khoom siv ua raws li cov koob yees duab IP los ntawm cov hom lag luam, lossis ua ke nrog PoE splitters rau cov khoom tsis yog-PoE, cov tshuaj no yuav tsum muaj cov khoom siv hluav taws xob sib cais (tsis suav nrog hauv pob). Cov neeg siv yuav tsum tau txais ib qho piv rau lawv qhov kev xav tau ntawm qhov hluav taws xob, kom ntseeg tau tias nws tsis tshaj DC48V los tiv thaiv kev puas tsuaj.

Cov lus no encapsulates cov ntsiab lus tshwj xeeb, kos los ntawm cov qauv kev coj ua hauv PoE engineering kom ntseeg tau tias cov neeg siv tuaj yeem soj ntsuam kev sib raug zoo nrog lawv cov kev teeb tsa network.

Qhov passive PoE injector no ua tau zoo hauv nws cov haujlwm tseem ceeb, sib xyaw ua ke nrog kev ua tau zoo. Tsis zoo li cov active injectors uas sib tham txog qib fais fab, qhov no tsis yog - qauv qauv muab lub zog passively, uas txhais tau hais tias nws yog ntsaws- thiab- ua si rau cov khoom siv sib xws- zoo tagnrho rau cov xwm txheej uas qhov kev xa tawm ceev yog qhov tseem ceeb tshaj qhov zoo tshaj plaws.
Cov yam ntxwv tseem ceeb suav nrog ntau-chaw nres nkoj efficiency: nrog 8 lub tswv yim thiab 8 qhov chaw tso zis, nws centralizes fais fab faib, txo cov cable clutter thiab lub sij hawm installation. Qhov ceev 100Mbps ua kom tsis muaj qhov cuam tshuam hauv kev xa cov ntaub ntawv, tswj kev sib raug zoo hauv network txawm tias nyob rau hauv kev thauj khoom. LED ntsuas muab qhov tseeb- lub sijhawm kuaj xyuas cov xwm txheej, pab cov kws tshaj lij daws teeb meem ntawm ib sab.
Nws kev sib raug zoo txuas mus rau ntau yam khoom siv, tab sis cov neeg siv yuav tsum txheeb xyuas tus pin teeb tsa kom tsis txhob muaj qhov tsis sib xws. Qhov kev tsim no txhawb nqa tus nqi-kev ua tau zoo, vim nws tsis tas yuav tsim- hauv kev txawj ntse, ua rau nws muaj peev xwm siv nyiaj- kev xaiv tus phooj ywg rau kev sib txuas lus. Hauv cov ntsiab lus kev lag luam, nws yog midspan injector uas txhaj lub zog tsis cuam tshuam cov ntaub ntawv ntws, ua raws li Ethernet cov qauv rau kev ua haujlwm txhim khu kev qha.

Hauv kev lag luam network engineering, passive PoE injectors zoo li qhov no pom lawv cov niche hauv cov ntawv thov xav tau kev xa hluav taws xob txhim khu kev qha nyob deb. Feem ntau, nws tsim nyog rau kev soj ntsuam, qhov twg IP koob yees duab xav tau lub zog tas li yam tsis muaj qhov chaw tshwj xeeb -xav tias cov tsev khaws khoom loj, thaj tsam sab nraum zoov, lossis kev teeb tsa hauv nroog.
Nws kuj tseem muaj txiaj ntsig hauv kev sib txuas lus wireless, siv cov ntsiab lus nkag hauv chaw ua haujlwm lossis chaw muag khoom kom txuas ntxiv Wi-Fi kev pab them nqi. Rau cov xov tooj VoIP lossis IoT cov cuab yeej, nws yooj yim rau kev koom ua ke hauv cov tsev ntse. Hauv tej thaj chaw deb lossis hnyav, xws li chaw tsim kho lossis kev saib xyuas kev ua liaj ua teb, nws qhov loj me thiab qhov kub thiab txias ua rau nws mus rau - xaiv.
B2B cov neeg siv feem ntau xa nws mus rau hauv kev sib xyaw ua ke, xws li kev sib txuas nrog cov keyboards rau kev tswj hwm kev sib txuas lus, ua kom cov khoom siv xws li sensors lossis LED teeb pom kev zoo nyob twj ywm yam tsis muaj kev cuam tshuam fais fab.

Thaum cov duab ntawm lub cev tsis tau kos ntawm no, xav txog qhov kev txhaj tshuaj raws li lub sleek, compact unit nrog kom meej meej RJ45 chaw nres nkoj rau cov ntaub ntawv tawm tswv yim thiab PoE cov zis. Lub vaj huam sib luag pem hauv ntej nta LED teeb rau txhua qhov channel, ci ntsuab thaum ua haujlwm. Cov hlau los yog cov yas yas ruaj ruaj ua kom muaj cua sov dissipation, nrog cov qhov cua kom tswj tau qhov kev ua tau zoo thaum siv txuas ntxiv. Mounting qhov tso cai rau kev teeb tsa phab ntsa lossis khib nyiab, thiab lub hwj chim input jack tau pom zoo tso rau kev sib txuas yooj yim. Qhov kev tsim qauv no tseem ceeb rau cov neeg siv- kev phooj ywg, nrog xim- cov chaw nres nkoj coded kom txo qis kev teeb tsa tsis raug hauv kev teeb tsa kev tshaj lij.

Los ntawm txoj kev pom kev, qhov ua tau zoo ntawm cov tshuaj tiv thaiv PoE passive yog qhov zoo -tsim nyob rau hauv cov ntaub ntawv sib tham. Kev tshawb fawb hauv hluav taws xob engineering qhia txog yuav ua li cas midspan zog txhaj tshuaj khaws cov ntaub ntawv ceev txog 100Mbps, raws li pom hauv cov qauv no, tsis muaj teeb liab degradation tshaj Cat.5 cables. Tiag -Kev xa tawm thoob ntiaj teb hauv kev ruaj ntseg ua kom pom kev txo qis, nrog lub zog ruaj khov ua kom muaj kev ua haujlwm 24/7 rau cov khoom siv tseem ceeb.
Kev sib raug zoo nrog IEEE cov qauv txhais tau hais tias nws ua raws li cov kev coj ua zoo tshaj plaws hauv ntiaj teb, qhov twg cov qauv siv tau zoo dua rau cov tsis yog - cov khoom sib tham los txiav cov nqi. Cov neeg siv kev paub dhau los hauv cov khoom zoo sib xws underscore nws txoj kev ntseeg siab, nrog rau qhov tsis ua haujlwm tsawg thaum lub zog nkag tau raug sib raug zoo, txhawb nqa nws lub luag haujlwm hauv B2B tes hauj lwm uas muaj peev xwm.

Raws li cov chaw tsim khoom cog lus rau B2B kev ua tau zoo, peb muab kev txhawb nqa tsim nyog los xyuas kom muaj kev sib koom ua ke. Peb pab neeg muab kev sib tham ua ntej - kev yuav khoom kom phim cov specs nrog koj cov kev xav tau, suav nrog cov lus pom zoo rau kev cai. Tshaj tawm-muag, nkag mus rau cov lus qhia thiab kev daws teeb meem ntawm email lossis xov tooj, nrog lub sijhawm teb sai.

Peb muab qhov tseem ceeb rau kev txiav txim ntau nrog cov kev xaiv thauj khoom yooj yim thiab kev tiv thaiv kev nyab xeeb rau lub siab.
