ONU ndiyo yatinowanzodaidza kuti "katsi diki", ONU low light inoreva chiitiko chekuti simba remagetsi rinogamuchirwa neONU riri pasi pesimba remagetsi rinogamuchirwa neONU. Kunzwa kwemagetsi kunogamuchirwa neONU kunoreva simba remagetsi shoma rinogona kuwanikwa neONU panguva yekushanda kwakajairika. Kazhinji, chiratidzo chemagetsi chinogamuchirwa cheONU yepamhepo i--27dBm; saka, simba remagetsi rinogamuchirwa neONU riri pasi pe--27dBm rinowanzotsanangurwa sechiedza cheONU chisina simba.

Pane zvinhu zvakawanda zvinokanganisa ruzivo rwemushandisi paindaneti. Mwenje mudiki weONU unonyanya kukanganisa kumhanya kwenetwork. Kuti vaedze kukanganiswa kwechiedza chisina kusimba cheONU pakumhanya kwenetwork yemushandisi, Laodingtonou akagadzira modhi yekuyedza inotevera.
Batanidza attenuator inogadziriswa uye PON optical power meter yakatevedzana pakati petambo yeganda neONU, kuitira kuti PON optical power meter ishandiswe kuyera simba reOptical rakagamuchirwa reONU (simba reOptical repazasi rebvunzo). Musiyano uripo pakati pesimba reOptical rakagamuchirwa reONU ungangoita 0.3dB (1 fiber jumper tisingabatanidzi attenuation ye active connection). Nzvimbo chaiyo yekuyedza yakaita seiyi.
Nekugadzirisa kudzikiswa kwe adjustable attenuator, kudzikiswa kweODN link kunogona kuwedzerwa, uye simba re optical rinogamuchirwa reONU rinogona kuchinjwa. Kuchinja kwekumhanya kwenetwork kunoedzwa nekubatanidza laptop kuONU ne network cable. Nzira iyi inoshandiswa kuyedza 300M broadband yeLaodingtoujia, uye mhedzisiro yebvunzo ndeiyi inotevera.
Kunzwa kwechokwadi kwekugamuchira kwemaONU mazhinji kuri nani pane index neinenge 1.0dB. Semuenzaniso, maONU ari mubvunzo uyu anogona kuramba achishanda zvakanaka kana simba rekugamuchira repamusoro riri pamusoro pe -27.98dBm. Kana simba rekugamuchira repamusoro riri pasi pe -27.98dBm, kumhanya kwenetwork yedownlink kunoderera nekukurumidza nekudzikira kwesimba rekugamuchira repamusoro, uye kunochengetedza kumhanya kwenetwork kwakaderera mukati meimwe nzvimbo yesimba repamusoro kusvika network yakanganiswa zvachose.
