Abasebenzi bezokuphepha abenze inethiwekhi ye-PON bayazi nge-ONU, okuyidivayisi yokufinyelela esetshenziswa kunethiwekhi ye-PON, okulingana nokushintsha kokufinyelela kunethiwekhi yethu evamile.
Inethiwekhi ye-PON iyinethiwekhi ye-optical engasebenzi. Isizathu sokuthi kuthiwa ayisebenzi ukuthi ukudluliswa kwefayibha ye-optical phakathi kwe-ONU ne-OLT akudingi imishini yokuphakelwa kwamandla. I-PON isebenzisa ifayibha eyodwa ukuxhuma ku-OLT, bese ixhuma ku-ONU.
Kodwa-ke, i-ONU yokuqapha inobunye bayo. Isibonelo, i-ONU-E8024F enomsebenzi we-PoE osanda kwethulwa yi-Sushan Weida iyi-EPON-ONU yezinga lezimboni ezingama-24-port 100M EPON-ONU. Zivumelanise nendawo yokusebenza engu-minus -18 ℃ - izinga lokushisa eliphakeme elingu-55 ℃. Ifanelekela ubuhlakani besistimu kanye nezimo zokuphepha zokuqapha ngaphansi kwezidingo zokushisa ezibanzi. Lokhu akutholakali emishinini evamile ye-ONU. I-ONU evamile ngokuvamile iyi-port ye-PON, futhi ine-port ye-PON kanye ne-port ye-PoE ngesikhathi esifanayo, okungenzi nje kuphela ukuthi ukuxhumana kube lula, kodwa futhi kusindisa okunye ukuphakelwa kwamandla kwekhamera 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 ihlinzeka ngamandla ekhamera ngembobo yayo ye-PoE. Akubonakali njengoshintsho olukhulu, kodwa kwezinye izindawo ezikhethekile, njengezimo ezinzima, ukungakwazi ukumba imigudu yokunikezwa kwamandla, kanye nokunikezwa kwamandla okungahambi kahle, kunenzuzo enkulu.
Ngicabanga ukuthi lo umehluko phakathi kwe-PON emkhakheni wokufinyelela i-broadband kanye nokuqapha. Vele, umsebenzi we-ONU one-PoE ungasetshenziswa futhi emkhakheni we-broadband.
Nakuba ukusetshenziswa kwemodi yokufinyelela ye-PON ekuqapheni kungekuningi kakhulu okwamanje, kungabonakala ukuthi ngokuthuthukiswa kwamadolobha aphephile namadolobha ahlakaniphile, ukusetshenziswa kwemodi yokufinyelela ye-PON kuzoba yinto evamile.
