Nhanganyaya:ONU(Optical Network Unit) yakakamurwa kuita inoshanda optical network mauniti uye passive optical network zvikamu.ONUchishandiso chemushandisi mune optical network, yakaiswa pamagumo emushandisi, uye inoshandiswa pamwe cheteOLTkuzadzisa Ethernet Layer 2 uye Layer 3 mabasa, ichipa vashandisi izwi, data, uye multimedia masevhisi.
Tsanangudzo yeONUpanel zviratidzo:
SIMBA mwenje: girini yadzima: dzima pa: simba pa
PON mwenje: Yakasvibira pa: Yakareba inoratidza kuti bhodhi rakapfuura bvunzo uye mudziyo uri kushanda zvakajairika
LOS rambi: kwete pa: normal state
Sarudza kukanganisa kwemushandisi:
Izvo zvinokanganisa zvakanyanya optical nzira kukanganisa uyeONUkukanganisa kwemudziyo. Chekutanga, tarisa kana mwenje wepaneti chiratidzo chakajairika. Tarisa mwenje wePON mamiriro ekukanganisa nzira: mwenje wePON unowanzo kuvhenekerwa mugirini, zvichiratidza kuti nzira yekuona yakajairika, uye mwenje wePON wakadzimwa, zvichiratidza kuti nzira yekuona yakatyoka.
Shandisa optical simba mita kuyedza nzira yekuona. Iyo inogamuchirwa huwandu hwesimba rekuona ndeiyi: 1490nm: - 8db kusvika - 28db. Kana huwandu hwapfuura, huchakanganisa hutano hwekushanda hweseONU, uye kupinda kweinternet kwemushandisi kuchakanganiswa. Tarisa iyo yekumusoro level optical nzira, uye enda kune yekuona tambo handover bhokisi kuti uedze muswe faibha yekupatsanura inoenderana neanokanganisa tambo yemushandisi.
Attenuation ye1: 2 chiteshi splitter ndeye - 3 db

Iyo attenuation ye1:32 chiteshi splitter iri - 15 db,
Iyo attenuation ye1:64 chiteshi splitter iri - 18db,
1, Kana iyo yakabuda optical simba ye splitter pigtail inokodzera, ndapota tsiva iyo fiber musimboti pakati peiyo optical cable junction bhokisi uye chivakwa. Kazhinji, isu tinoisa anokwana maviri fiber cores kuchivakwa, uye tozoitisa yekupedzisira kuyedzwa mushure mekutsiva. Kana iyo optical simba ye pigtail kubva kune splitter isingakodzeri, ndapota shandura iyo yakasara pigtail, uye shandisa optical simba mita kuti uedze munhu akakodzera kuti ubatanidze kune pigtail yekuvaka.
Kana iri optical nzira kukanganisa: Kutanga, sunungura pigtail paONUkuedza simba remaziso. Kana pasina chiedza kana simba risina kukodzera, tapota tsvaga imwe ye1-32 pigtails inoenderana neONUpane flange ye optical cable junction bhokisi, uye bvisa pigtail kubva kune flange kuti uedze simba rekuona. Kana iyo pigtail isingakodzeri, shandura chero ipi zvayo ye1-32 idle pigtails. Yeuka kuti iyo huru fiber ye splitter haigoni kusunungurwa, iyo inobata zvoseONUs.

Mushure mekunge mudziyo uchishanda zvakajairika, tsvaga zvimwe zvikonzero. Nzira yacho yakafanana neyakatsanangurwa pamusoro apa.
