Kwicandelo lothungelwano kunye nokuhanjiswa kwedatha, ukuhlanganiswa kwetekhnoloji yePower over Ethernet (PoE) kuyitshintshe ngokupheleleyo indlela izixhobo ezisebenza ngayo kwaye ziqhagamshelwe ngayo. Enye yezo nguqu yiI-POE ONU, isixhobo esinamandla esidibanisa amandla enethiwekhi ye-optical engasebenziyo (i-PON) kunye nokusebenza okulula kwe-PoE. Le blogi iza kuhlola imisebenzi kunye neenzuzo ze-POE ONU kunye nendlela etshintsha ngayo imeko yokudluliselwa kwedatha kunye nokunikezelwa kwamandla.
I-POE ONU sisixhobo esinezinto ezininzi esibonelela nge-1 G/EPON adaptive PON port ye-uplink kunye ne-8 10/100/1000BASE-T electrical port ye-downlink. Olu lungiselelo luvumela ukudluliselwa kwedatha okungenamthungo kunye noqhagamshelo lwezixhobo ezahlukeneyo. Ukongeza, i-POE ONU ixhasa ukusebenza kwe-PoE/PoE+, inika ukhetho lokunika amandla iikhamera ezixhunyiweyo, iindawo zokufikelela (ii-AP) kunye nezinye iiterminals. Lo msebenzi uphindwe kabini wenza i-POE ONU ibe yinxalenye ebalulekileyo yenethiwekhi yanamhlanje kunye neenkqubo zokujonga.
Enye yezona nzuzo ziphambili ze-POE ONUs kukukwazi kwazo ukwenza lula nokusasazwa kwezixhobo ezidityanisiweyo. Ngokudibanisa imisebenzi yokuhambisa idatha kunye nokunikezelwa kombane kwisixhobo esinye, ii-POE ONUs zisusa isidingo sombane owahlukileyo kunye neentambo zezixhobo ezidityanisiweyo. Oku akunciphisi nje kuphela ixesha lokufaka kunye neendleko, kodwa kwandisa ukusebenza kakuhle kunye nokuthembeka kweziseko zenethiwekhi.
Ii-POE ONU zilungele ngokukodwa usetyenziso olufana nokujonga i-IP apho uqhagamshelo lwedatha kunye neemfuno zamandla zibalulekile. Ukufakwa kunye nokugcinwa kwenziwa lula ngokukwazi ukunika amandla iikhamera kunye nezinye izixhobo zokujonga ngqo kwi-ONU. Oku kuluncedo ngakumbi kwiindawo zangaphandle okanye ezikude apho ukufikelela kumbane kunokuthintelwa khona.
Ukongeza, inkxaso ye-POE ONU kwimisebenzi ye-PoE/PoE+ yongeza ukuguquguquka okongezelelweyo kunye nokukhula kwinethiwekhi. Izixhobo ezisebenzisa i-PoE zinokudityaniswa kwaye zinikwe amandla ngokulula ngaphandle kwesidingo see-adaptha zamandla ezongezelelweyo okanye iziseko zophuhliso. Oku kwenza kube lula ukwandiswa kunye nolawulo lwenethiwekhi, okuvumela ukuhlanganiswa okungenamthungo kwezixhobo ezintsha njengoko inethiwekhi ikhula.
Kufuphi,I-POE ONUimele ukuhlanganiswa okunamandla kokudluliselwa kwedatha kunye nokukwazi ukubonelela ngombane. Amandla ayo okubonelela ngoqhagamshelo olukhawulezayo kunye nokuhanjiswa kwamandla kwisixhobo esinye, esincinci kuyenza ibe yimpahla exabisekileyo kwizicelo zanamhlanje zothungelwano kunye nokujonga. Njengoko imfuno yeziseko zophuhliso zenethiwekhi ezisebenzayo nezithembekileyo iqhubeka ikhula, ii-POE ONUs ziba sisisombululo esiguquguqukayo nesibalulekileyo sokuhanjiswa kwedatha kunye nokunikezelwa kombane okuphuculweyo.
