    Hukama pakati peOLT neONU

    Nguva yekutumira: Mar-06-2023

    OLT: Inoreva iyo optical line terminal yatinoshandisa, uye zvakare ndiyo yekupedzisira terminal michina inoshandiswa kubatanidza optical fiber trunk.

    ONU: ONUzvinoreva optical network unit.ONUinonyanya kukamurwa kuita inoshanda optical network unit uye passive optical network unit. Kazhinji, michina ine network yekutarisa inosanganisira optical receiver, uplink Optical transmitter uye akawanda mabhiriji amplifiers anonzi "optical node".

    OLTndiyo midziyo yehofisi muEPON passive optical network system. Iyo yakawanda-sevhisi inopa chikuva, iyo inogona kutsigira IP masevhisi uye echinyakare TDM masevhisi panguva imwe chete. Icho chishandiso chakaiswa kumucheto kwemetropolitan nharaunda network uye pakubuda kwenharaunda yekuwana network, iyo inogona kushandura masevhisi ekuwana uye kuvaendesa kune IP network zvichiteerana.

    TheONU1001i uplink inobatanidza kuhofisi yepakati kuburikidza neGEPON port, uye iyo downlink inogona kupa gigabit Ethernet ports yevashandisi vega kana vamwe vashandisi. Semhinduro yeramangwana yeFTTx,ONU1001i inopa izwi rine simba, data-kumhanya uye masevhisi evhidhiyo kuburikidza ne-single-fiber GEPON.ONUbasa: sarudza kugamuchira data inotumirwa naOLT; Pindura kumarudzi uye simba rekudzora mirairo inotumirwa neOLT; Uye gadzirisa zvinoenderana; Yemushandisi Ethernet data inochengetwa uye inotumirwa kune iyo uplink nzira muhwindo rekutumira rakagoverwa naOLT.
