Vanhu vekuchengetedza vakamboshanda mumaPON network vanoziva ONU, inova mudziyo we access terminal unoshandiswa muPON network, izvo zvakafanana ne access switch munetwork yedu yatinogara tichiita.
Network yePON inetwork ye optical passive. Chikonzero nei ichinzi haishande ndechekuti optical fiber transmission pakati peONU neOLT haidi michina yemagetsi. PON inoshandisa optical fiber imwe chete kuti ibatanidzwe neOLT, uye OLT inobva yabatanidzwa neONU.
Zvisinei, ONU yehutano ine hunhu hwayo hwakasiyana. Sisitimu iyi inogona kungoona nekutarisa mamiriro ekuchengetedza chete kana paine zvinodiwa pakupisa kwakakura. Izvi hazviwanikwe mumidziyo yakajairika yeONU. ONU yakajairika inowanzova bhatani rePON, uye ine PON. Uye POE port, uye ine PON port uye PoE port panguva imwe chete, izvo hazvingoiti kuti network ichinjike chete, asiwo zvinochengetedza simba rekuwedzera rekamera yekutarisa.
Musiyano mukuru pakati peONU yakajairika neONU inotsigira PoE ndewekuti yekutanga inogona kushandiswa chete seyuniti ye optical network kupa kutumira data. Yekutanga haingogone kutumira data chete, asi inogonawo kubatana nekamera kuburikidza nePoE port yayo kuti ipe simba. Zvingasaita sekuchinja kukuru, asi mune dzimwe nzvimbo dzakakosha, dzakadai senzvimbo dzisina kunaka, kutadza kuchera magetsi, magetsi asina kunaka, nezvimwewo, ine mabhenefiti makuru.
Ndinofunga uyu ndiwo musiyano uripo pakati pePON mumunda wekuwana nekukurumidza uye wekutarisa. Ehe, ONU ine POE function inogonawo kushandiswa mumunda webroadband.
Kunyangwe kushandiswa kwenzira yePON mukutarisa kusina kuwanda zvakanyanya, zvinogona kuonekwa kuti nekuvandudzwa kwemaguta akachengeteka nemaguta akangwara, kushandiswa kwenzira dzePON kuchava nyaya yechokwadi.
