Emkhakheni wokuxhumana kanye nokudluliswa kwedatha, ukuhlanganiswa kobuchwepheshe be-Power over Ethernet (PoE) kushintshe ngokuphelele indlela amadivayisi asebenza futhi axhunywe ngayo. Enye into entsha enjalo yi-I-POE ONU, idivayisi enamandla ehlanganisa amandla enethiwekhi ye-optical engasebenzi (i-PON) kanye nokusebenza kwe-PoE okulula. Le bhulogi izohlola imisebenzi nezinzuzo ze-POE ONU nokuthi ishintsha kanjani isimo sokudluliswa kwedatha kanye nokunikezwa kwamandla.
I-POE ONU iyidivayisi enemisebenzi eminingi enikeza imbobo ye-PON eguquguqukayo engu-1 G/EPON ye-uplink kanye nama-port kagesi angu-8 10/100/1000BASE-T ye-downlink. Lokhu kulungiselelwa kuvumela ukudluliswa kwedatha okungenamthungo kanye nokuxhumeka kwamadivayisi ahlukahlukene. Ngaphezu kwalokho, i-POE ONU isekela ukusebenza kwe-PoE/PoE+, inikeza inketho yokunika amandla amakhamera axhunyiwe, izindawo zokufinyelela (ama-AP) kanye nezinye iziteshi. Lo msebenzi ophindwe kabili wenza i-POE ONU ibe yingxenye ebalulekile yezinhlelo zenethiwekhi zanamuhla kanye nokuqapha.
Enye yezinzuzo eziyinhloko zama-POE ONU yikhono lawo lokwenza lula nokusabalalisa amadivayisi axhunyiwe. Ngokuhlanganisa imisebenzi yokudlulisa idatha kanye nokunikezwa kwamandla kudivayisi eyodwa, ama-POE ONU aqeda isidingo semithombo kagesi ehlukile kanye nokufakwa kwezintambo kumadivayisi axhunyiwe. Lokhu akugcini nje ngokunciphisa isikhathi sokufaka kanye nezindleko, kodwa futhi kwandisa ukusebenza kahle kanye nokuthembeka kwengqalasizinda yenethiwekhi.
Ama-POE ONU afaneleka kakhulu ezinhlelweni zokusebenza ezifana nokuqapha i-IP lapho ukuxhumana kwedatha nezidingo zamandla kubalulekile khona. Ukufakwa nokugcinwa kwenziwa kube lula ngekhono lokunika amandla amakhamera neminye imishini yokuqapha ngqo kusuka ku-ONU. Lokhu kuzuzisa kakhulu ezindaweni ezingaphandle noma ezikude lapho ukufinyelela kwamandla kungase kulinganiselwe khona.
Ngaphezu kwalokho, ukusekelwa kwe-POE ONU kwemisebenzi ye-PoE/PoE+ kunezela ukuguquguquka okwengeziwe kanye nokukhula kunethiwekhi. Amadivayisi asebenzisa i-PoE angahlanganiswa kalula futhi anikwe amandla ngaphandle kwesidingo sama-adaptha kagesi engeziwe noma ingqalasizinda. Lokhu kwenza kube lula ukunwetshwa nokuphathwa kwenethiwekhi, okuvumela ukuhlanganiswa okungenamthungo kwamadivayisi amasha njengoba inethiwekhi ikhula.
Kafushane,I-POE ONUimelela ukuhlanganiswa okunamandla kwamakhono okudlulisa idatha kanye nokunikezwa kwamandla. Amandla ayo okuhlinzeka ngokuxhumeka okusheshayo kanye nokulethwa kwamandla kudivayisi eyodwa, encane kuyenza ibe yimpahla ebalulekile yezinhlelo zokusebenza zenethiwekhi zanamuhla kanye nokuqapha. Njengoba isidingo sengqalasizinda yenethiwekhi esebenza kahle futhi ethembekile siqhubeka nokukhula, ama-POE ONU aba yisisombululo esiguquguqukayo nesibalulekile sokudluliselwa kwedatha okuthuthukisiwe kanye nokunikezwa kwamandla.
