Mphamvu pa Efaneti (POE)luso lamakono lasintha momwe timagwiritsira ntchito zida zathu, kupereka zosavuta, zogwira mtima komanso zochepetsera mtengo.Mwa kuphatikiza mphamvu ndi kutumiza deta pa chingwe cha Ethernet, POE imachotsa kufunikira kwa chingwe chamagetsi chosiyana, ndikupangitsa kuti ikhale yabwino kwa ntchito zosiyanasiyana monga makamera a IP, malo opanda waya, ndi mafoni a VoIP.Komabe, tisanagwiritse ntchito njira iliyonse pamanetiweki, ndikofunikira kumvetsetsa kusiyana pakati pa masiwichi amtundu wa POE ndi omwe si a POE.

Kusintha kokhazikika kwa POE kumatsata miyezo ya Institute of Electrical and Electronics Engineers (IEEE) 802.3af kapena 802.3at.Miyezo yodziwika ndi mafakitale iyi imatchula mphamvu yayikulu kwambiri yomwe switch imatha kubweretsa ku zida zogwirizana ndi POE.Mphamvu yodziwika kwambiri pakusintha kwa POE ndi 48V.

Kumbali ina, masinthidwe a POE omwe si amtundu wamba sangagwirizane ndi miyezo ya IEEE iyi.Nthawi zambiri amagwiritsa ntchito njira za eni zomwe zimasiyana ndi zomwe zakhazikitsidwa.Ngakhale ma switch awa angawoneke ngati njira yotheka chifukwa cha mtengo wake wotsika, alibe kugwirizana komanso kudalirika kwa masiwichi wamba a POE.Ndikofunika kumvetsetsa kusiyana pakati pa ziwirizi ndi zoopsa zomwe zingatheke zokhudzana ndi zosavomerezekaKusintha kwa POE.

Kusiyanitsa kumodzi kwakukulu pakati pa masinthidwe amtundu wa POE ndi omwe sali wamba ndi mphamvu yomwe amapereka pazida zolumikizidwa.StandardKusintha kwa POEntchito pa 48V mphamvu.Zosankha izi zimavomerezedwa ndi anthu ambiri ndikuthandizidwa ndi zida zambiri zothandizidwa ndi POE pamsika.Amapereka mphamvu yodalirika, yosasunthika, kuonetsetsa kuti ntchito yosasunthika ikugwira ntchito komanso ntchito yabwino.

Mosiyana ndi izi, ma switch a POE omwe sali okhazikika amagwiritsa ntchito ma voliyumu ena kupatula 48V.Ngakhale ena mwa masinthidwewa amapereka mphamvu zoperekera mphamvu zapamwamba, samayenderana ndi zida zodziwika bwino za POE.Kusagwirizana kumeneku kungayambitse zinthu zosiyanasiyana, kuphatikizapo kusowa mphamvu, kuchepa kwa kachipangizo, komanso kuwonongeka kwa zipangizo zolumikizidwa.

Kuti musiyanitse masiwichi a POE okhazikika komanso osakhazikika, yambani poyang'ana momwe magetsi amaperekedwa ndi wopanga ma switch.Kusintha kogwirizana kudzawonetsa bwino ngati akugwirizana ndi IEEE 802.3af kapena 802.3at standard, komanso ma voliyumu omwe amathandizira.Zosinthazi ziziwonetsa kuchuluka kwamphamvu kwamagetsi padoko lililonse, kuwonetsetsa kuti mutha kugwiritsa ntchito zida za POE mosatetezeka.

Kumbali inayi, masinthidwe a POE omwe si amtundu wamba sangatsatire miyezo yodziwika bwino iyi.Atha kutulutsa mphamvu zambiri kapena kugwiritsa ntchito ma voliyumu omwe sali okhazikika, monga 12V kapena 56V.Samalani poganizira za mtundu uwu wa kusintha chifukwa sangakupatseni mphamvu zomwe chipangizo chanu chimafuna kapena zingayambitse chipangizocho kulephera msanga.

Njira ina yosiyanitsira ma switch a POE okhazikika ndi omwe si amtundu wamba ndikudalira opanga zida zodziwika bwino zama netiweki.Opanga okhazikika amapanga masiwichi odalirika komanso okhazikika a POE omwe amatsatira zomwe makampani amafunikira.Amayesedwa mwamphamvu kuti akwaniritse miyezo yapamwamba komanso kupereka magwiridwe antchito apamwamba.

Mukafuna masiwichi a POE, mutha kulumikizana nafe nthawi iliyonse.Kampani yathu,JHA Tech, yakhala ikuyang'ana pa R & D, kupanga ndi kugulitsa zosintha zosiyanasiyana kuyambira 2007. Sizingokhala ndi phindu lalikulu kwambiri pamtengo, komanso zimatsimikiziridwa kwambiri mu khalidwe chifukwa tapeza ziphaso zamaluso ndi zovomerezeka;
