Vashandi vekuchengetedza vakamboshandisa PON network vanoziva nezve ONU, inova mudziyo wekupinda unoshandiswa muPON network, inova yakafanana ne access switch munetwork yedu yatinogara tichiita.
Network yePON inetwork ye optical isingashande. Chikonzero nei ichinzi haisi kushanda ndechekuti kufambiswa kwe optical fiber pakati peONU neOLT hakudi michina yemagetsi. PON inoshandisa fiber imwe chete kuti ibatanidze kuOLT, iyo inobva yabatana neONU.
Zvisinei, ONU yekutarisa ine hunhu hwayo hwakasiyana. Semuenzaniso, ONU-E8024F ine PoE function yakatangwa nguva pfupi yadarika naSushan Weida iindasitiri ine madoko makumi maviri nemana e100M EPON-ONU. Inofanira kushandiswa munzvimbo yekushanda ye minus -18 ℃ - tembiricha yepamusoro ye55 ℃. Yakakodzera kungwara kwesystem uye kutarisa mamiriro ekuchengetedza pasi pezvinodiwa zvekupisa kwakafara. Izvi hazviwanikwe mumidziyo yakajairika yeONU. ONU yakajairika inowanzova doko rePON, uye ine doko rePON nedoko rePoE panguva imwe chete, izvo hazvingoiti kuti network ive nyore kuchinja, asiwo zvinochengetedza imwe simba rekamera yekutarisa.
Musiyano mukuru pakati peONU yakajairika neONU inotsigira PoE ndewekuti yekutanga inogona kushandiswa chete seyuniti ye optical network kupa kutumira data. Yekutanga haingogone chete kutumira data, asiwo kupa simba kukhamera kuburikidza nePoE port yayo. Hazviratidzike seshanduko huru, asi mune dzimwe nzvimbo dzakakosha, dzakadai senzvimbo dzakaoma, kutadza kuchera matunnel ekupa magetsi, uye kupa magetsi kusina kunaka, zvinobatsira zvikuru.
Ndinofunga uyu ndiwo musiyano uripo pakati pePON mumunda wekuwana broadband nekutarisa. Ehe, basa reONU rine PoE rinogonawo kushandiswa mumunda webroadband.
Kunyangwe kushandiswa kwePON access mode mukutarisa kusina kuwanda zvakanyanya pari zvino, zvinogona kuonekwa kuti nekuvandudzwa kwemaguta akachengeteka nemaguta akangwara, kushandiswa kwePON access mode kuchava nyaya yechokwadi.
