Emkhakheni wokuxhumana nokudluliswa kwedatha, ukuhlanganiswa kobuchwepheshe be-Power over Ethernet (PoE) kushintshe ngokuphelele indlela amadivaysi anikwa amandla futhi axhumeke ngayo. Enye yezinto ezintsha ezinjalo yi-POE ONU, idivayisi enamandla ehlanganisa amandla enethiwekhi ye-passive optical (i-PON) nokunethezeka kokusebenza kwe-PoE. Le bhulogi izohlola imisebenzi nezinzuzo ze-POE ONU nokuthi ishintsha kanjani isimo sokudluliswa kwedatha kanye nokunikezwa kwamandla.
I-POE ONU iyidivayisi enemisebenzi eminingi enikezela ngembobo ye-PON eguquguqukayo engu-1 G/EPON ku-uplink kanye nezimbobo zikagesi ezingu-8 10/100/1000BASE-T ze-downlink. Lokhu kulungiselelwa kuvumela ukudluliswa kwedatha okungenazihibe kanye nokuxhumana kwamadivayisi ahlukahlukene. Ngaphezu kwalokho, i-POE ONU isekela ukusebenza kwe-PoE/PoE +, ihlinzeka ngenketho yokunika amandla amakhamera axhunyiwe, izindawo zokufinyelela (ama-AP) nezinye iziphetho. Lo msebenzi ombaxambili wenza i-POE ONU ibe yingxenye ebalulekile yenethiwekhi yesimanje kanye nezinhlelo zokugada.
Enye yezinzuzo eziyinhloko zama-POE ONU yikhono lawo lokwenza lula nokwenza lula ukuthunyelwa kwamadivayisi anenethiwekhi. Ngokuhlanganisa ukudluliswa kwedatha nemisebenzi yokuphakelwa kwamandla edivayisini eyodwa, ama-POE ONU aqeda isidingo sokuphakelwa kwamandla okuhlukene kanye nekhebula kumadivayisi axhunyiwe. Lokhu akugcini nje ukunciphisa isikhathi sokufaka nezindleko, kodwa futhi kwandisa ukusebenza kahle okuphelele nokuthembeka kwengqalasizinda yenethiwekhi.
Ama-POE ONU afaneleka kakhulu izinhlelo zokusebenza ezifana nokugadwa kwe-IP lapho uxhumo lwedatha nezimfuneko zamandla zibalulekile. Ukufaka nokunakekela kwenziwa kwaba lula ngekhono lokunika amandla amakhamera nezinye izinto zokugada ngokuqondile kusuka ku-ONU. Lokhu kunenzuzo ikakhulukazi ezindaweni ezingaphandle noma ezikude lapho ukufinyelela kwamandla kungase kukhawulelwe.
Ngaphezu kwalokho, ukusekelwa kwe-POE ONU kwemisebenzi ye-PoE/PoE+ kwengeza ukuguquguquka okwengeziwe nokuqina kunethiwekhi. Amadivayisi ane-PoE angahlanganiswa kalula futhi anikwe amandla ngaphandle kwesidingo sama-adaptha amandla engeziwe noma ingqalasizinda. Lokhu kwenza kube lula ukunwetshwa kwenethiwekhi nokuphatha, okuvumela ukuhlanganiswa okungenazihibe kwamadivayisi amasha njengoba inethiwekhi ikhula.
Kafushane,POE ONUimele ukuhlanganiswa okunamandla kokudluliswa kwedatha namandla okuphakela amandla. Ikhono layo lokuhlinzeka ngoxhumano lwesivinini esikhulu kanye nokulethwa kwamandla kudivayisi eyodwa, ehlangene kuyenza ibe yimpahla ebalulekile yokuxhumana kwesimanjemanje kanye nezinhlelo zokusebenza zokugada. Njengoba isidingo sengqalasizinda yenethiwekhi esebenza kahle nethembekile siqhubeka sikhula, i-POE ONUs iba yisixazululo esiguquguqukayo nesibalulekile sokudluliswa kwedatha okuthuthukisiwe kanye nokuphakelwa kwamandla.
