    Nhanganyaya kune ONU michina

    Nguva yekutumira: Zvita-16-2020

    ONU(Optical network unit) Optical node.ONUyakakamurwa kuita active optical network unit uye library passive optical network unit.Kazhinji, midziyo ine network monitoring inosanganisira optical receiver, uplink optical transmitter uye akawanda mabhiriji amplifiers anonzi optical node.

    ONUFunction

    1, Sarudza kugamuchira nhepfenyuro data inotumirwa neOLT;
    2, Pindura kumirairo yekutenderera uye simba rekutonga rakapihwa neOLT; uye gadzirisa zvinoenderana;
    3, Chengetedza data reEthernet remushandisi uye utumire kumusoro kumusoro muhwindo rekutumira rakagoverwa neOLT.

    ONUEquipment

    Teerera zvizere neIEEE 802.3/802.3ah

    ·Kugamuchira kunzwa kunosvika -25.5dBm

    ·Tumira simba kusvika -1 kusvika +4dBm

    ·PON inoshandisa imwe optical fiber kubatanidza kune iyoOLT, uyezveOLTinobatanidza kuONU. ONUinopa masevhisi akadai sedata, IPTV (kureva inopindirana network terevhizheni), izwi (richishandisa IAD, kureva Integrated Access Device) nemamwe masevhisi, kunyatsoona "kutamba-katatu" zvikumbiro.

    ·Yepamusoro mwero PON: symmetrical 1Gb/s kukwira nekudzika dhata, VoIP izwi uye IP vhidhiyo masevhisi.

    ·ONU"Plug uye Tamba" zvichibva pakuwana otomatiki uye kugadzirisa

    ·Yepamusoro mhando yebasa (QoS) mabasa anoenderana nesevhisi level chibvumirano (SLA) kuchaja

    ·Remote manejimendi masimba anotsigirwa neakapfuma uye ane simba OAM mabasa

    ·High senitivity mwenje inogamuchira uye yakaderera yekuisa mwenje mashandisiro emagetsi

    ·Tsigira Kufa Gasp basa
