Zvizhinji zvezvikanganiso ndeye optical fiber line kukanganisa uyeONUzvikanganiso zvemidziyo. Kutanga, tarisa kana chiratidzo chepaneru chakajairika. Kana pane optical fiber line kukundikana, ona mamiriro ePON chiedza: kana chiedza chePON chakasvibirira, chinoratidza kuti optical fiber line yakajairika, uye kana chiedza chePON chikadzimwa, chinoratidza kuti optical fiber line yakabviswa.
Edza iyo optical fiber mutsetse ine optical simba mita. Iyo inokodzera huwandu hwesimba rekuona ndeiyi: 1490nm renji: - 8dB kusvika - 28dB. Kana ikadarika huwandu, inokanganisa hutano hwekushanda hweONUuye kuwana kweInternet kwemushandisi kuchakanganiswa. Tarisa iyo yekumusoro level optical fiber mutsara uye yedza muswe faibha yekupatsanura inoenderana neanokanganisa mushandisi optical tambo pane optical cable bhokisi.

1.Kana iyo yakabuda optical simba ye splitter pigtail inokodzera, ndapota shandura iyo fiber core pakati pe optical cable transfer box uye chivako. Kazhinji, isu tinoisa anokwana maviri fiber cores muchivako, uye tozoedza kumagumo mushure mekutsiva. Kana iri muswe kubva kune splitter uye simba rayo rekupenya refiber risina kukodzera, tapota shandura spare pigtail, uye shandisa optical power meter kuti uedze munhu akakodzera kuti abatanidze kune pigtail yekuvaka.
2.Kana iyo optical fiber line inokanganisa: tanga kubvisa pigtail paONUkuti uedze simba remaziso, kana pasina chiedza kana simba risina kukodzera, tapota enda kune flange ye optical cable transfer box kuti uwane imwe ye1-32 pigtails ye optical splitter inoenderana neONUKana iyo pigtail isina kukodzera, unogona kutsiva chero ipi zvayo ye1-32 isina basa pigtails. Yeuka: iyo huru fiber ye optical splitter haigoni kubudiswa kunze, iyo inobata zvoseONU.
