I-PoE (Amandla phezu kwe-Ethernet) ibhekisela emandleni phezu kobuchwepheshe be-Ethernet adlulisela amandla kanye nedatha ngesikhathi esisodwa ngekhebula epheya esontekile. Ukusetshenziswa kwalobu buchwepheshe kungathuthukisa ngempumelelo ukuzinza nokuguquguquka kwenethiwekhi, ngakho-ke kuthandwa kakhulu ngabantu. Njengamanje, kunezinhlelo zokusebenza ezahlukahlukene ezisuselwa kubuchwepheshe be-PoE emakethe, njengokushintshwa kwe-Gigabit PoE, izinsiza zamandla ze-PoE, izihlukanisi ze-PoE, njalonjalo.

I-Outdoor PoE Injector POE++ 60/90w 802.3af/at

Yini i-PoE injector?

I-PoE injector ibizwa nangokuthi i-midspan, ishaja ye-PoE noma i-adaptha ye-PoE. Ixhuma amaswishi angewona e-PoE namadivayisi anikwe amandla e-PoE (PD) ngezintambo zenethiwekhi (njenge-Cat5eCat6Cat6a, njll.) esebenzayo. Lo mshini ngokuvamile ulungele izindawo ezidinga ukufaka isisetshenziswa esinamatheminali anamandla amancane kodwa ezingenazo izindawo zokuphuma kukagesi. Lesi sixazululo sifinyelela ngempumelelo ukuthuthukiswa okukhulu kokuguquguquka kwenethiwekhi ngezindleko eziphansi, ukuze ukufakwa kwemishini kungasavinjelwa ukwakhiwa kwendawo kanye nenethiwekhi ekhona.

Izinzuzo ze-PoE injector zibonakala kakhulu kulezi zici ezilandelayo:
*Kulula ukuyifaka: Vele uxhume ugesi kumshini wetheminali we-PoE kanye neswishi ukuze unikeze amandla nokusekelwa kokudluliswa kwedatha.
*Kulula ukunwebeka: Ukukhishwa kwesiginali yedatha ngeswishi engeyona ye-PoE kungajovwa kusiginali yamandla ngentambo yenethiwekhi, ukuze kuhlinzekwe amandla nokwesekwa kokudluliselwa kwedatha kudivayisi enikwe amandla ngesikhathi esifanayo, okuletha ukunethezeka okwengeziwe. ekuxhumekeni kwedivayisi.
*Yonga izindleko: Ukusetshenziswa kwamandla e-PoE kungagcina ukwakheka kwenethiwekhi yasekuqaleni kusisekelo sokusetshenziswa okusebenzayo kwempahla yokuqala, ngaleyo ndlela konga kakhulu izindleko.

Uhlobo lomjovo we-PoE:

Ukunikezwa kwamandla kwe-PoE okujwayelekile kanye nokunikezwa kwamandla we-PoE okungajwayelekile

Ukunikezwa kwamandla okujwayelekile kwe-PoE kubhekisela ekunikezeni amandla okuthobela izindinganiso zemboni ye-PoE (njenge-IEEE802.3af, IEEE802.3at noma izinga lakamuva le-IEEE802.3bt). Ngaphansi kwezinga lemboni ye-PoE engu-802.3af, 802.3at noma 802.3bt, okokusebenza okuphakela amandla kagesi kwe-PoE (PSE) kanye nesisetshenziswa esinamandla zizoxoxisana ngokuzenzakalelayo lapho zixhumekile, futhi ukuxoxisana kungaba yimpumelelo kuphela uma izisetshenziswa kuzo zombili iziphetho zivumelana imodi ejwayelekile efanayo. Ngemuva kokuthi ukuxoxisana phakathi kwalawa madivayisi womabili kube yimpumelelo, idivayisi yokuphakela amandla izonikeza amandla kudivayisi enikwe amandla. Kule ndlela yokusebenza yobuchwepheshe obujwayelekile be-PoE, ukuphepha kwemishini ye-PoE kungaqinisekiswa ngokuqinile. Ngokuvamile, i-voltage engu-802.3af, 802.3at noma 802.3bt ejwayelekile yokuphakela amandla ingu-44-57V (DC).

Ukunikezwa kwamandla kwe-PoE okungajwayelekile ngokuvamile kubhekisela ezintweni zikagesi ezingathobeli noma yimaphi amazinga emboni ye-PoE (njengamazinga e-IEEE802.3af, IEEE802.3at noma IEEE802.3bt). Amandla kagesi wokusebenza wezinto ezingajwayelekile ze-PoE ngokuvamile angu-18-48V (DC). Uma amanani kagesi emishini emibili exhunyiwe engahambelani, angabangela umonakalo unomphela ocingweni.

12V/24V/48V PoE amandla

Ukunikezwa kwamandla kwe-PoE kungahlukaniswa ngezinhlobo ezintathu ngokuya nge-voltage ephumayo: 12V, 24V kanye ne-48V. Lapho uthenga ugesi we-PoE, udinga ukucabangela ukuthi i-voltage yedivayisi ye-PoE exhunywe kuyo iyahambisana yini.

Ngaphezu kwalezi zigaba ezimbili ezishiwo ngenhla zokuphakelwa kukagesi, i-PoE Injector ingabuye ihlukaniswe ngokwenani lamachweba ahlukene, njengokuphakelwa kukagesi kwe-PoE enechweba elilodwa kanye nokuphakelwa kukagesi kwe-PoE enamachweba ayisishiyagalombili nokunye.
