Yintoni iteknoloji yePOE?

I-PoE (Power Over Ethernet) ibhekisa kubuchwepheshe obunika amandla eDC kwezinye iitheminali ezisekwe kwi-IP (umzekelo, iifowuni ze-IP, indawo yofikelelo ye-LAN engenazingcingo, iikhamera zenethiwekhi, njl.njl.) ngelixa uthumela imiqondiso yedatha kwizixhobo ezinjalo ngaphandle kweyiphi na.

utshintsho kwiziseko ezingundoqo esele zikhona.

a

Amacandelo enkqubo ye-PoE.

Isixokelelwano esipheleleyo siquka i-PSE (IsiXhobo sokuThweba saMandla) kunye nePD (isiXhobo saMandla).I-PSE sisixhobo esinika amandla kwizixhobo zabaxhasi be-Ethernet kwaye ingumphathi wayo yonke inkqubo ye-POE yamandla phezu kwe-Ethernet.Ugqithiso

eliphakathi liqulatheiintloko zekristale, iimodyuli (POE), iipaneli zepatch kunye neentambo zenethiwekhi.

b

Iimeko zesicelo semveliso.

Isetyenziswa kwiinkqubo zezixhobo ezahlukeneyo ezixhaswe bubuchwephesha bePOE.Ekubeni izixhobo ze-elektroniki ezisebenza nge-Ethernet zinokusetyenziswa ngaphandle kweendawo zombane ezongezelelweyo, ixesha kunye nemali echithwe ekuqwalaseleni iintambo zombane zinokugcinwa kwaye

iindleko zenkqubo yonke zinokuncitshiswa.

Izicelo zee-POE ezingasebenzi ngeengcingo

Ukusetyenziswa kwe-POE yokubeka iliso ekude

Ukusetyenziswa kweetheminali ezikrelekrele zePOE

Okwangoku, iindawo ezininzi zasekhaya kunye neentambo zonxibelelwano zaseTshayina ziqulethe i-halogen, kwiingozi ezininzi zomlilo zasekhaya kwiminyaka yamuva nje, amaxhoba akanako ukubaleka i-90% ngenxa yokuba i-cable combustion ikhupha igesi enetyhefu enetyhefu, kwaye ukutsha kukhululwe ubushushu obuninzi, umsi, bangela ukuba amaxhoba aphefumle ubunzima, akhokele kwintlekele!Kwezinye iindawo ezinoxinano olukhulu lwezithuthi, ezifana nezikhululo zikaloliwe, izikhululo zeenqwelomoya, amaziko eenkomfa nemiboniso, izibhedlele, izakhiwo zeeofisi zodidi oluphezulu, njalo njalo, iDatang Cable ikuncomela iintambo zeLSZH.I-Datang Telecom iphantsi komsi weemveliso zentambo ze-halogen ezikumgangatho obalaseleyo, izixhobo ezigqwesileyo, ukukhuselwa kokusingqongileyo okuluhlaza, akunakuhlangabezana kuphela nemigangatho yomgangatho womlilo welizwe kunye nezoshishino, okona kubaluleke kakhulu, ukukhapha ukhuseleko lwakho.
