I-PoE (Amandla phezu kwe-Ethernet) ibhekisela kumandla phezu kweteknoloji ye-Ethernet ehambisa amandla kunye nedatha ngaxeshanye ngentambo ephothiweyo. Ukusetyenziswa kobu buchwepheshe kunokuphucula ngokufanelekileyo uzinzo kunye nokuguquguquka kwenethiwekhi, ngoko ke ithandwa kakhulu ngabantu. Okwangoku, kukho izicelo ezahlukeneyo ezisekelwe kwitekhnoloji ye-PoE kwimarike, njengokutshintsha kwe-Gigabit PoE, izixhobo zombane ze-PoE, ii-splitters ze-PoE, njalo njalo.

Yintoni i-PoE injector?

Isitofu se-PoE ikwabizwa ngokuba yi-midspan, itshaja ye-PoE okanye iadaptha ye-PoE. Idibanisa i-non-PoE switches kunye ne-PoE powered devices (PD) ngokusebenzisa iintambo zenethiwekhi (ezifana neCat5eCat6Cat6a, njl.) ezisebenzayo. Esi sixhobo sifanelekile ngokubanzi kwiindawo ezifuna ukufakela izixhobo zetheminali ezinamandla aphantsi kodwa zinqongophele iindawo zokukhupha umbane. Esi sisombululo sifezekisa ngokufanelekileyo uphuculo olukhulu kuthungelwano bhetyebhetye ngexabiso eliphantsi, ukwenzela ukuba ukufakwa kwezixhobo kungasathintelwa yijografi kunye nezakhiwo zenethiwekhi ezikhoyo.

Uncedo lwe-PoE injector lubonakaliswa ikakhulu kule miba ilandelayo:
*Kulula ukuyifaka: Qhagamshela nje unikezelo lwamandla kwisixhobo se-terminal ye-PoE kunye nokutshintsha ukunika amandla kunye nenkxaso yokuhanjiswa kwedatha.
*Kulula ukwandisa: Imveliso yesignali yedatha yi-non-PoE switch inokutofwa kwisignali yamandla ngentambo yenethiwekhi, ukwenzela ukunika amandla kunye nenkxaso yokuhanjiswa kwedatha kwisixhobo esinikwe amandla ngaxeshanye, nto leyo ezisa lula ngakumbi. kuqhagamshelwano lwesixhobo.
*Gcina iindleko: Ukusetyenziswa kombane we-PoE kunokugcina uyilo lwenethiwekhi yokuqala ngokwesiseko sosetyenziso olusebenzayo lwesixhobo sokuqala, ngaloo ndlela konga kakhulu iindleko.

Uhlobo lwesitofu se-PoE:

UBonelelo lwaMandla oMgangatho wePoE kunye noBonelelo loMbane lwePoE olungengomGangatho

Ubonelelo lwamandla oMgangatho wePoE lubhekisa kubonelelo lwamandla oluhambelana nemigangatho yoshishino ye-PoE (efana ne-IEEE802.3af, IEEE802.3at okanye umgangatho we-IEEE802.3bt wamva nje). Ngaphantsi komgangatho woshishino we-PoE we-802.3af, 802.3at okanye 802.3bt, izixhobo zokubonelela umbane we-PoE (PSE) kunye nesixhobo esinamandla siya kuthetha-thethana ngokuzenzekelayo xa zixhunyiwe, kwaye uthetha-thethwano lunokuphumelela kuphela xa izixhobo kuzo zombini iziphelo zihambelana imo yomgangatho ofanayo. Emva kokuba uthethathethwano phakathi kwezi zixhobo zimbini luphumelele, isixhobo sokubonelela ngombane siya kunika amandla kwisixhobo esinamandla. Kule ndlela yokusebenza yeteknoloji ye-PoE esemgangathweni, ukhuseleko lwezixhobo ze-PoE lunokuqinisekiswa ngamandla. Ngokubanzi, i-802.3af, 802.3at okanye i-802.3bt yombane oqhelekileyo wonikezelo lwamandla yi-44-57V (DC).

Ubonelelo lwamandla lwe-PoE olungengomgangatho luqhelekileyo lubhekiselele kunikezelo lwamandla olungahambelaniyo nayo nayiphi na imigangatho yoshishino ye-PoE (enjenge-IEEE802.3af, IEEE802.3at okanye imigangatho ye-IEEE802.3bt). Umbane osebenzayo wezixhobo ze-PoE ezingekho mgangathweni ngokuqhelekileyo yi-18-48V (DC). Ukuba amaxabiso ombane ezixhobo ezibini eziqhagamshelweyo awahambelani, oko kunokubangela umonakalo osisigxina kwisixhobo.

12V/24V/48V PoE unikezelo lwamandla

Unikezelo lwamandla e-PoE lunokwahlulwa lube ziindidi ezintathu ngokuhambelana nombane wokuphuma: 12V, 24V kunye ne-48V. Xa uthengela umbane we-PoE, kufuneka uqwalasele ukuba i-voltage yesixhobo se-PoE esiqhagamshelwe kuyo iyahambelana.

Ukongeza kwezi ndidi zimbini zikhankanywe ngasentla zobonelelo lwamandla, i-PoE Injector inokwahlulwa ngokwenani lamazibuko ahlukeneyo, afana ne-single-port PoE power supply kunye ne-8-port PoE power supply njalo njalo.
