Mphamvu ya kuwala kofooka kwa ONU pa liwiro la netiweki

ONU ndizomwe timachitcha kuti "light cat", ONU low light imatanthawuza chodabwitsa kuti mphamvu ya kuwala yomwe imalandira ndi ONU imakhala yochepa kusiyana ndi kumvera kwa ONU.Kulandira kumva kwa ONU kumatanthawuza mphamvu yochepa ya kuwala yomwe ONU ingalandire panthawi ya ntchito yachibadwa.Nthawi zambiri, cholozera cholandirira cha burodibandi yanyumba ONU ndi -27dBm;Choncho, ONU yolandira mphamvu ya kuwala yotsika kuposa -27dBm imatanthauzidwa ngati kuwala kofooka kwa ONU.

ONU ndizomwe timachitcha kuti "light cat", ONU low light imatanthawuza chodabwitsa kuti mphamvu ya kuwala yomwe imalandira ndi ONU imakhala yochepa kusiyana ndi kumvera kwa ONU.Kulandira kumva kwa ONU kumatanthawuza mphamvu yochepa ya kuwala yomwe ONU ingalandire panthawi ya ntchito yachibadwa.Nthawi zambiri, cholozera cholandirira cha burodibandi yanyumba ONU ndi -27dBm;Choncho, ONU yolandira mphamvu ya kuwala yotsika kuposa -27dBm imatanthauzidwa ngati kuwala kofooka kwa ONU.

Pali zinthu zambiri zomwe zimakhudza zomwe wogwiritsa ntchito akugwiritsa ntchito pa intaneti.Kuwala kotsika kwa ONU kumakhudza kwambiri liwiro la netiweki.Pofuna kuyesa mphamvu ya kuwala kofooka kwa ONU pa liwiro la intaneti ya wogwiritsa ntchito, Laodingtou anamanga chitsanzo chotsatira choyesera.

Lumikizani chowongolera chosinthika ndi mita yamphamvu ya PON yotsatizana pakati pa chingwe chachikopa ndi ONU, kotero kuti mita yamphamvu ya PON ingagwiritsidwe ntchito kuyeza mphamvu yolandila ya ONU (yotsika kumunsi kwa mphamvu yakuyesa).Kusiyana pakati pa mphamvu ya kuwala yolandirira ya ONU ndi pafupifupi 0.3dB (1 fiber jumper kuchotsera kuchepetsedwa kwa kulumikizana kogwira).Malo enieni oyesera ndi awa.

Mwa kusintha kuchepetsedwa kwa attenuator yosinthika, kuchepetsedwa kwa ulalo wa ODN kungawonjezeke, ndipo mphamvu yolandila ya ONU ingasinthidwe.Kusintha kwa liwiro la netiweki kumayesedwa polumikiza laputopu ku ONU ndi chingwe cha netiweki.Njirayi imagwiritsidwa ntchito poyesa burodibandi ya 300M ya Laodingtoujia, ndipo zotsatira zake ndi izi.

Kulandila kwenikweni kwa ma ONU ambiri ndikwabwino kuposa index ndi pafupifupi 1.0dB.Mwachitsanzo, ma ONU mu mayesowa amatha kugwirabe ntchito bwino pomwe mphamvu yolandila yolandila ili yayikulu kuposa -27.98dBm.Pamene mphamvu yolandira kuwala imakhala yocheperapo kuposa -27.98dBm, liwiro la intaneti la downlink limatsika mofulumira ndi kuchepa kwa mphamvu yolandira kuwala, ndipo imakhala ndi liwiro lochepa kwambiri la intaneti mkati mwa mtundu wina wa kuwala kwa magetsi mpaka intaneti itasokonezeka.
