    OLT uye ONU

    Nguva yekutumira: Jun-14-2024

    Optical access network (kureva kuti, network yekupinda ine chiedza senzira yekutapurirana, pachinzvimbo chemhangura waya, inoshandiswa kuwana mhuri yega yega. Optical access network).Optical access network kazhinji ine zvikamu zvitatu: Optical line terminalOLT, Optical network unitONU, optical distribution networkODN,umoOLT uyeONUndizvo zvakakosha zvikamu zve optical access network

    OLTinomirira Optical Line Terminal.OLTndiyo optical line terminal, ndiyo nhare yehofisi midziyo, inoshandiswa kubatanidza optical fiber trunk, basa racho rakafanana nechinjaor routermune yechinyakare kutaurirana network, mudziyo wekunze network yekupinda uye yemukati network yekupinda. Yakaiswa kumagumo emunharaunda, anonyanya kukosha mabasa ekutonga kurongeka kwetraffic, buffer control, uye kupa mushandisi-yakatarisana nepassive fiber network interface uye kugovera bandwidth. Zvichitaurwa zviri nyore, ndiko kuita mabasa maviri, kumusoro kwemvura, kupedzisa kukwira kumusoro kwePON network; Pasi, iyo data yakawanikwa inotumirwa kune veseONUmushandisi terminal zvishandiso kuburikidza neODN network.

    ONUndiyo Optical Network Unit.ONUine mabasa maviri: kusarudza kugamuchira nhepfenyuro inotumirwa naOLT, uye kugamuchira mhinduro kuneOLTkana iyo data inoda kugamuchirwa; Unganidza uye chengetedza iyo Ethernet data iyo mushandisi inoda kutumira, uye tumira iyo cached data kune iyoOLTterminal zvinoenderana nehwindo rekutumira rakapihwa.

    PaThe FTTx network (tinya pano Kuti udzidze nekukurumidza nezveFTTx), iyoONUnzira yekuwana inosiyana nekutumirwa kwakasiyana. Semuenzaniso, Fiber To The Curb (FTTC): IyoONUinoiswa mukamuri yepakati pemidziyo yesero. FTTB(Fiber Kuchivakwa):ONUinoiswa mubhokisi rekupedzisira rekoridho; FTTH(Fiber Kumba Kumba): IyoONUinoiswa mumushandisi wepamba.

    OLTndiyo manejimendi terminal,ONUndiyo terminal; Kuvhurwa kwesevhisi kweONUinounzwa kuburikidzaOLT, uye ukama huri pakati pevaviri nditenzi-muranda. MultipleONUsinogona kubatanidzwa neOLTkuburikidza nekupatsanura.

    ODN iOptical Distribution Network, inotaridzika yekugovera network, yemuviri chiteshi chekufambisa kwemaziso pakati.OLTuyeONU. Basa rayo guru nderokupedzisa bidirectional kutapurirana kwezviratidzo zvemaziso. Inowanzo kuumbwa neoptical fiber uye tambo, optical connector, optical splitter, uye midziyo yekubatsira yekuisa nekubatanidza zvishandiso izvi. Chimwe chezvinhu zvinonyanya kukosha ndeye optical splitter.

    HDVinogona kupa vatengi huwandu hwakazara hweFTTH zvigadzirwa nemhinduro. Yakavambwa muna 2012, HDV ndeye-yekumira mhinduro inopa uye ODM & OEM mugadziri wemafiber kuwana network. Zvinoenderana nezvinodiwa nevatengi, tinogona kubatsira vatengi kugadzira zvirongwa zvekugadzira zvigadzirwa zvinodhura uye zvigadzirwa zvakagadziridzwa, uye nekupa vimbiso yemhando yeODM & OEM masevhisi. Ranga richiomerera kumweya wekubatana, kushanda nesimba, hunyanzvi, kushanda nesimba uye kuvimbika, iine yakasimba R & D tekinoroji kugona uye yakakwana yekutumira sisitimu, kupa vatengi vane yepamusoro-yemhando yepamusoro optical fiber yekutaurirana michina zvigadzirwa uye tekinoroji mhinduro, ngatishandei. pamwe chete, kuhwina-kuhwina ramangwana!
