Abantu bezokuphepha abake basebenza kumanethiwekhi e-PON bayazi i-ONU, okuyidivayisi yesiphelo sokufinyelela esetshenziswa kunethiwekhi ye-PON, okulingana neswishi yokufinyelela kunethiwekhi yethu evamile.
Inethiwekhi ye-PON iyinethiwekhi ye-optical engasebenzi. Isizathu sokuthi kuthiwa ayisebenzi ukuthi ukudluliswa kwe-optical fiber phakathi kwe-ONU ne-OLT akudingi mishini yamandla. I-PON isebenzisa i-optical fiber eyodwa ukuxhuma ku-OLT, bese i-OLT ixhunywe ku-ONU.
Kodwa-ke, i-ONU yezempilo inobunye bayo. Uhlelo lungaqaphela futhi luqaphe izimo zokuphepha kuphela ngaphansi kwezidingo zokushisa ezibanzi. Lokhu akutholakali emishinini evamile ye-ONU. I-ONU evamile ngokuvamile iyinkinobho ye-PON, futhi ine-PON. Ne-POE port, futhi ine-PON port kanye ne-PoE port ngesikhathi esifanayo, okungenzi nje kuphela ukuthi inethiwekhi iguquguquke, kodwa futhi konga amandla engeziwe ekhamera yokuqapha.
Umehluko omkhulu phakathi kwe-ONU evamile ne-ONU esekela i-PoE ukuthi eyokuqala ingasetshenziswa kuphela njengeyunithi yenethiwekhi yokukhanya ukunikeza ukudluliswa kwedatha. Eyokuqala ayikwazi ukudlulisa idatha kuphela, kodwa futhi ingaxhuma kwikhamera ngembobo yayo ye-PoE ukuze inikeze amandla. Kungase kungabonakali njengoshintsho olukhulu, kodwa kwezinye izindawo ezikhethekile, njengendawo embi, ukungakwazi ukumba ukunikezwa kwamandla, ukunikezwa kwamandla okungahambi kahle, njll., inezinzuzo ezinkulu.
Ngicabanga ukuthi lo umehluko phakathi kwe-PON emkhakheni wokufinyelela okusheshayo kanye nokuqapha. Vele, i-ONU enomsebenzi we-POE ingasetshenziswa futhi emkhakheni we-broadband.
Nakuba ukusetshenziswa kwendlela yokufinyelela i-PON ekuqapheni kungebanzi kakhulu, kungabonakala ukuthi ngokuthuthukiswa kwamadolobha aphephile namadolobha ahlakaniphile, ukusetshenziswa kwezindlela zokufinyelela i-PON kuzoba yinto evamile.
