Uyini umehluko phakathi kwe-ONU evamile kanye ne-ONU esekela i-PoE?

Abasebenzi bezokuphepha abenze inethiwekhi ye-PON ngokuyisisekelo bazi nge-ONU, okuyidivayisi yokufinyelela esetshenziswa kunethiwekhi ye-PON, elingana neswishi yokufinyelela kunethiwekhi yethu evamile.

Inethiwekhi ye-PON iyinethiwekhi yokubona engenzi lutho.Isizathu sokuthi kungani kuthiwa ayisebenzi ukuthi ukudluliswa kwe-fiber optical phakathi kwe-ONU ne-OLT akudingi noma yiziphi izisetshenziswa zokuphakela amandla.I-PON isebenzisa i-fiber eyodwa ukuxhuma ku-OLT, ebese ixhuma ku-ONU.

Nokho, i-ONU yokuqapha inokwehluka kwayo.Isibonelo, i-ONU-E8024F enomsebenzi we-PoE esanda kwethulwa ngu-Sushan Weida iyimboni yezinga lemboni engu-24-port 100M EPON-ONU.Ivumelane nendawo yokusebenza yokususa -18 ℃ - izinga lokushisa eliphezulu lika-55 ℃.Ilungele ubuhlakani besistimu nokuqapha izimo zokuphepha ngaphansi kwezidingo zokushisa ezibanzi.Lokhu akutholakali ezintweni ezijwayelekile ze-ONU.I-ONU evamile ngokuvamile iyimbobo ye-PON, futhi inembobo ye-PON kanye nembobo ye-PoE ngesikhathi esifanayo, okungenzi nje kuphela ukuthi inethiwekhi iguquguquke, kodwa futhi igcina okunye ukunikezwa kwamandla kwekhamera yokugada.

Umehluko omkhulu phakathi kwe-ONU evamile kanye ne-ONU esekela i-PoE ukuthi eyokuqala ingasetshenziswa kuphela njengeyunithi yenethiwekhi yokubona ukuze kuhlinzekwe ukudluliswa kwedatha.Eyangaphambili ayikwazi ukudlulisa idatha kuphela, kodwa futhi inikeze amandla ekhamera ngembobo yayo ye-PoE.Akubonakali njengoshintsho olukhulu, kodwa kwezinye izindawo ezikhethekile, njengezindawo ezinokhahlo, ukungakwazi ukumba imigudu yokunikezwa kwamandla kagesi, kanye nokuphakelwa kukagesi okungalungile, kunenzuzo kakhulu.

Ngicabanga ukuthi lona umehluko phakathi kwe-PON emkhakheni wokufinyelela nokuqapha kwe-broadband.Kunjalo, i-ONU enomsebenzi we-PoE ingasetshenziswa futhi emkhakheni we-broadband.

Nakuba ukusetshenziswa kwemodi yokufinyelela ye-PON ekuqapheni akubanzi kakhulu okwamanje, kungabonakala ukuthi ngokuthuthukiswa kwamadolobha aphephile namadolobha ahlakaniphile, ukusetshenziswa kwemodi yokufinyelela ye-PON kuzoba yindaba.
