Kwintsimi yothungelwano kunye nokuhanjiswa kwedatha, ukuhlanganiswa kwe-Power over Ethernet (PoE) iteknoloji iye yatshintsha ngokupheleleyo indlela izixhobo ezisebenza ngayo kwaye zixhunyiwe. Enye into entsha enjaloPOE ONU, isixhobo esinamandla esidibanisa amandla enethiwekhi ye-passive optical network (PON) kunye nokusebenziseka lula kwePoE. Le bhlog iya kuphonononga imisebenzi kunye neenzuzo ze-POE ONU kunye nendlela etshintsha ngayo indawo yokuhanjiswa kwedatha kunye nokunikezelwa kwamandla.
I-POE ONU sisixhobo esinemisebenzi emininzi esinika i-1 G / EPON i-adaptive PON port kwi-uplink kunye ne-8 10/100/1000BASE-T izibuko zombane ze-downlink. Olu lungelelwaniso luvumela ugqithiso lwedatha olungenamthungo kunye noqhagamshelwano lwezixhobo ezahlukeneyo. Ukongezelela, i-POE ONU isekela ukusebenza kwe-PoE / PoE +, inika inketho yokunika amandla iikhamera ezixhunyiwe, iindawo zokufikelela (APs) kunye nezinye ii-terminals. Lo msebenzi umbini wenza i-POE ONU ibe yinxalenye ebalulekileyo yenethiwekhi yanamhlanje kunye neenkqubo zokucupha.
Enye yeenzuzo eziphambili ze-POE ONUs kukukwazi kwabo ukwenza lula kunye nokwenza lula ukuthunyelwa kwezixhobo zothungelwano. Ngokudibanisa ukuhanjiswa kwedatha kunye nemisebenzi yonikezelo lwamandla kwisixhobo esinye, ii-POE ONUs zisusa imfuno yonikezelo lwamandla olwahlukileyo kunye nekhebhuli yezixhobo ezixhunyiwe. Oku akugcini nje ukunciphisa ixesha lokufakela kunye neendleko, kodwa kwandisa ukusebenza kakuhle kunye nokuthembeka kweziseko zenethiwekhi.
Ii-POE ONU zifanelekile ngokukodwa kwizicelo ezifana ne-IP surveillance apho uqhagamshelwano lwedatha kunye neemfuno zamandla zibalulekile. Ukufakela kunye nokugcinwa kwenziwa lula ngokukwazi ukunika amandla iikhamera kunye nezinye izixhobo zokucupha ngokuthe ngqo kwi-ONU. Oku kuluncedo ngakumbi kwiindawo ezingaphandle okanye ezikude apho ukufikelela kombane kunokuncitshiswa.
Ukongeza, inkxaso ye-POE ONU yemisebenzi ye-PoE/PoE + yongeza ukuguquguquka okongezelelweyo kunye nokusabalalisa kwinethiwekhi. Izixhobo ezinikwe amandla e-PoE zinokudityaniswa ngokulula kwaye zinikwe amandla ngaphandle kwesidingo seeadaptha zamandla ezongezelelweyo okanye iziseko zoncedo. Oku kwenza lula ukwandiswa kwenethiwekhi kunye nolawulo, okuvumela ukudityaniswa komthungo kwezixhobo ezitsha njengoko uthungelwano lukhula.
Kufuphi,POE ONUimele ukudityaniswa okunamandla kokuhanjiswa kwedatha kunye nobuchule bokubonelela ngombane. Ikhono layo lokubonelela ngesantya esiphezulu sokuqhagamshelwa kunye nokunikezelwa kwamandla kwisixhobo esinye, esihlangeneyo senza ukuba ibe yimpahla exabisekileyo kwinethiwekhi yanamhlanje kunye nezicelo zokucupha. Njengoko imfuno yeziseko zonxibelelwano ezisebenzayo nezithembekileyo ziqhubeka nokukhula, ii-POE ONUs ziba sisisombululo esiguquguqukayo nesibalulekileyo sokuhanjiswa kwedatha kunye nonikezelo lwamandla.
