    Taw qhia rau ONU cov cuab yeej

    Post lub sij hawm: Dec-16-2020

    ONU(optical network unit) kho qhov muag node.ONUyog muab faib ua active optical network unit thiab tsev qiv ntawv passive optical network unit. Feem ntau, cov khoom nruab nrog network xyuas nrog rau optical receiver, uplink optical transmitter thiab ntau yam choj amplifiers hu ua optical node.

    ONUMuaj nuj nqi

    1 、 Xaiv kom tau txais cov ntaub ntawv tshaj tawm xa los ntawm tusOLT;
    2 、 Teb rau qhov sib txawv thiab lub zog tswj cov lus txib tawm los ntawm lubOLT; thiab ua kom raug hloov kho;
    3 、 Cache tus neeg siv cov ntaub ntawv Ethernet thiab xa mus rau saum toj kawg nkaus hauv lub qhov rai xa khoom faib los ntawmOLT.

    ONUKhoom siv

    Ua raws li IEEE 802.3 / 802.3ah

    ·Tau txais rhiab heev txog -25.5dBm

    ·Fais fab mus txog -1 txog +4dBm

    ·PON siv ib qho kev kho qhov muag fiber ntau los txuas rauOLT, thiab tom qab ntawdOLTtxuas rauONU. ONUmuab cov kev pabcuam xws li cov ntaub ntawv, IPTV (xws li kev sib tham sib network TV), lub suab (siv IAD, piv txwv li Integrated Access Device) thiab lwm yam kev pabcuam, ua tiag tiag "triple-play" daim ntawv thov

    ·Tus nqi siab tshaj PON: symmetrical 1Gb / s cov ntaub ntawv nce thiab nqis qis, VoIP suab thiab IP kev pabcuam video

    ·ONU"Plug thiab Ua Si" raws li kev tshawb pom tsis siv neeg thiab teeb tsa

    ·Cov kev pabcuam zoo tshaj plaws (QoS) ua haujlwm raws li kev pom zoo qib kev pabcuam (SLA) them

    ·Kev tswj chaw taws teeb muaj peev xwm txhawb nqa los ntawm kev nplua nuj thiab muaj zog OAM ua haujlwm

    ·High rhiab heev lub teeb tau txais thiab tsawg input teeb lub zog noj

    ·Txhawb Dying Gasp muaj nuj nqi
