Mau Oyamba: ONU (Optical Network Unit) imagawidwa kukhala yogwira ntchito yamagetsi yamagetsi ndi gawo lopanda mawonekedwe a netiweki, ONU ndi chipangizo chogwiritsira ntchito pa intaneti yowunikira, yomwe imayikidwa kumapeto kwa wogwiritsa ntchito, yogwiritsidwa ntchito ndi OLT kukwaniritsa Efaneti Layer 2, Layer 3 ntchito. , kuti apatse ogwiritsa ntchito mawu, data ndi ma multimedia.
Kufotokozera kwa gulu la ONU:
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 ndi zolakwika za zida za ONU.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 kuchuluka kwake, ikhudza momwe ONU amagwirira ntchito bwino ndipo kugwiritsa ntchito intaneti kwa wogwiritsa ntchito kumakhudzidwa.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 fiber optical uli wolakwika: choyamba chotsani pigtail pa ONU kuyesa mphamvu ya kuwala, ngati palibe kuwala kapena mphamvuyo siili yoyenerera, chonde pitani ku flange ya bokosi lotengera chingwe kuti mupeze imodzi. 1-32 pigtails ya optical splitter yofanana ndi ONU Ngati pigtail ndi yosayenerera, mukhoza kusintha iliyonse ya 1-32 pigtails zopanda pake.Kumbukirani: ulusi waukulu wa optical splitter sungathe kutulutsidwa, zomwe zidzakhudza ONU yonse.
Kufotokozera kwa gulu la ONU:
Kuwala kwamphamvu: Kuwala kobiriwira kumakhala koyaka nthawi zonse: Yatsani;Kuzimitsa kobiriwira: Kuzimitsa
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.
LAN1, LAN2, LAN3 ndi LAN4 onse ndi 4RJ45 Port
FXS1 ndi Voice Port
Kuthetsa Mavuto: Choyamba, fufuzani ngati chipangizo cha ONU chikuyenda bwino (ngati kuwala kwachidziwitso pagawo la chipangizocho ndi kozolowereka), ndiyeno fufuzani zifukwa zina chipangizo chitatha.Ndondomekoyi ndi yofanana ndi yomwe ili pamwambapa.
Kuti mumve zambiri zanzeru za ONU / bokosi ONU / kulumikizana kwa ONU / optical fiber ONU, mutha kulumikizana mwachindunji ndi HDV Phoelectron Technology LTD kuti mumve zambiri.Kampani yathu ilinso ndi zinthu zoyankhulirana za OLT, Media Converter, Switch ndi SFP.Takulandirani kuti mukambirane.
Kuchokera kwa opanga anu anzeru ONU&SFP.
