Chiyambi:ONU(Optical Network Unit) imagawidwa kukhala yogwira ntchito yolumikizana ndi ma network ndi passive optical network unit,ONUndi chipangizo chogwiritsira ntchito pa intaneti ya optical, choyikidwa kumapeto kwa wosuta, chogwiritsidwa ntchito ndiOLTkuti mukwaniritse Ethernet Layer 2, Layer 3 ntchito, kuti mupatse ogwiritsa ntchito mawu, data ndi ma multimedia.
ONUKufotokozera kwa gulu:
Kuwala kwamphamvu: Kuwotcha Kubiriwira: Kulephera kwamagetsi; Green On: Yatsani
Kuwala kwa PON: Kuwala kobiriwira: nthawi yayitali kukuwonetsa kuti bolodi yadziyesa yokha ndipo zida zimagwira ntchito bwino.
Kuwala kwa LOSS: Kuzimitsa: Mwachizolowezi
Yerekezerani cholakwika cha ogwiritsa ntchito:
Zolakwika zambiri ndi zolakwika za optical fiber line ndiONUzida zolakwika. Choyamba, fufuzani ngati chizindikiro cha gululo ndichabwinobwino. Ngati kulephera kwa mzere wa optical fiber, onani momwe kuwala kwa PON kulili: ngati kuwala kwa PON kuli kobiriwira, kumasonyeza kuti mzere wa optical fiber ndi wachilendo, ndipo ngati kuwala kwa PON kwazimitsidwa, kumasonyeza kuti mzere wa optical fiber wachotsedwa.
Yesani mzere wa fiber optical ndi mita yamphamvu ya kuwala. Mitundu yoyenerera ya mphamvu ya kuwala ndi: 1490nm osiyanasiyana: - 8dB mpaka - 28dB. Ngati ipitilira muyeso, ikhudza magwiridwe antchito abwinobwinoONUndipo kugwiritsa ntchito intaneti kwa wogwiritsa ntchito kudzakhudzidwa. Yang'anani mzere wapamwamba wa fiber fiber ndikuyesa ulusi wamchira wa chogawaniza chogwirizana ndi chingwe cholakwika cha wogwiritsa ntchito pabokosi la chingwe cha Optical.
Kuchepetsa kwa 2-way Optical splitter ndi -3db
The attenuation wa 4-njira kuwala splitter ndi -6db
Kuchepetsa kwa 8-way Optical splitter ndi -9db
The attenuation wa 16-njira kuwala splitter ndi -12db
The attenuation wa 32-njira kuwala splitter ndi -15db
The attenuation wa 64-njira kuwala splitter ndi -18db
1.Ngati mphamvu yotulutsa kuwala kwa splitter pigtail ndiyoyenera, chonde sinthani nsonga ya fiber pakati pa bokosi lotengera chingwe cha kuwala ndi nyumbayo. Nthawi zambiri, timayika ma fiber osachepera awiri mnyumbamo, kenako ndikuyesa kumapeto pambuyo posintha. Ngati ndi mchira kuchokera ku ziboda ndipo mphamvu yake kuwala kwa CHIKWANGWANI si oyenerera, chonde m'malo pigtail spare, ndi ntchito kuwala mphamvu mita kuyesa woyenerera kuti agwirizane ndi nyumba pigtail.
2.Ngati mzere wa kuwala kwa fiber ndi wolakwika: choyamba chotsani pigtail paONUkuyesa mphamvu ya kuwala, ngati kulibe kuwala kapena mphamvu ndi yosayenerera, chonde pitani ku flange ya bokosi lotengera chingwe kuti mupeze imodzi mwa 1-32 pigtails ya optical splitter yogwirizana ndiONUNgati pigtail ili yosayenerera, mutha kusintha mtundu uliwonse wa pigtails 1-32 zopanda pake. Kumbukirani: ulusi waukulu wa optical splitter sungathe kutulutsidwa, womwe ungakhudze onseONU.

Kuwala kwa LOSS: KUCHOKERA: Mphamvu yolandira kuwala ya doko la PON ndi yachilendo; Kuwala kobiriwira kumayaka nthawi zonse: Chipangizocho chapezeka ndikulembetsedwa; Kuphethira kobiriwira: Chipangizocho chilibe deta; Blink: Doko la PON liribe kuwala kapena mphamvu ya kuwala ndi yotsika kusiyana ndi kumvera.

Kuthetsa mavuto: Choyamba, fufuzani ngatiONUChipangizo chikuyenda bwino (ngati chowunikira pagawo la chipangizocho ndichabwinobwino), ndiyeno fufuzani zifukwa zina chipangizocho chikagwira ntchito moyenera. Ndondomekoyi ndi yofanana ndi yomwe ili pamwambapa.
