Kufurira kweONU mwenje usina simba pane network kumhanya

ONU ndiyo yatinowanzo kudana kuti "light cat", ONU low light inoreva chiitiko chekuti simba rekuona rinogamuchirwa neONU ishoma pane kugamuchira kunzwa kweONU.Kunzwa kwekugamuchira kweONU kunoreva simba rekuona zvishoma iro ONU inogona kugamuchira panguva yekushanda.Kazhinji, iyo yekugamuchira senitivity index yeimba Broadband ONU ndeye -27dBm;saka, iyo ONU inogamuchira optical power yakaderera pane -27dBm inowanzotsanangurwa seONU isina kusimba mwenje.

ONU ndiyo yatinowanzo kudana kuti "light cat", ONU low light inoreva chiitiko chekuti simba rekuona rinogamuchirwa neONU ishoma pane kugamuchira kunzwa kweONU.Kunzwa kwekugamuchira kweONU kunoreva simba rekuona zvishoma iro ONU inogona kugamuchira panguva yekushanda.Kazhinji, iyo yekugamuchira senitivity index yeimba Broadband ONU ndeye -27dBm;saka, iyo ONU inogamuchira optical power yakaderera pane -27dBm inowanzotsanangurwa seONU isina kusimba mwenje.

Pane zvakawanda zvinokanganisa ruzivo rwemushandisi online.Iyo ONU yakaderera mwenje inonyanya kukanganisa network kumhanya.Kuti uedze mabatiro eONU isina kusimba mwenje panetiweki kumhanya kwemushandisi, Laodingtou yakavaka inotevera bvunzo modhi.

Batanidza attenuator inogadziriswa uye PON optical power meter mumutsara pakati petambo yeganda neONU, kuitira kuti PON optical power mita inogona kushandiswa kuyera yakagamuchirwa optical simba reONU (iyo yakadzika pasi optical simba rekuedza).Musiyano uripo pakati pesimba rakagamuchirwa rekuona reONU rinenge 0.3dB (1 fiber jumper minus attenuation yekubatana kunoshanda).Iyo chaiyo test site yakaita seiyi.

Nekugadzirisa kuderedzwa kweiyo inogadziriswa attenuator, kuderedzwa kweiyo ODN link inogona kuwedzerwa, uye yakagamuchirwa optical simba reONU rinogona kuchinjwa.Shanduko yekumhanyisa network inoedzwa nekubatanidza laptop kuONU netambo yetiweki.Iyi nzira inoshandiswa kuyedza iyo 300M Broadband yeLaodingtoujia, uye mhinduro dzebvunzo ndedzinotevera.

Iko kugashira chaiko kwekunzwa kwemaONU mazhinji kuri nani pane index neinosvika 1.0dB.Semuenzaniso, maONU ari muyedzo iyi anogona achiri kushanda zvakajairika kana iyo yekugamuchira yekuona simba iri pamusoro -27.98dBm.Kana iyo yakagamuchirwa simba rekuona yakaderera pane -27.98dBm, iyo downlink network inomhanya inodonha nekukurumidza nekuderera kweiyo yakagamuchirwa optical simba, uye inochengetedza yakaderera kwazvo network kumhanya mukati meimwe optical simba renji kusvika network yakanganiswa zvachose.
