    Isingeniso semishini ye-ONU

    Isikhathi sokuthumela: Dec-16-2020

    I-ONU(iyunithi yenethiwekhi yokubona) inodi yokubona.I-ONUihlukaniswe yaba iyunithi yenethiwekhi ye-optical esebenzayo kanye neyunithi yenethiwekhi yelabhulali ye-passive optical. Ngokuvamile, okokusebenza okufakwe ukuqapha kwenethiwekhi okuhlanganisa isitholi sokubonwayo, i-uplink optical transmitter kanye nama-multiple bridge amplifiers kuthiwa yi-optical node.

    I-ONUUmsebenzi

    1, Khetha ukuthola idatha yokusakaza ethunyelwe yi-OLT;
    2, Phendula emiyalweni esukela kanye nokulawula amandla ekhishwe yi-OLT; futhi wenze izinguquko ezihambisanayo;
    3, Gcina idatha ye-Ethernet yomsebenzisi bese uyithumela enhla nomfula efasiteleni lokuthumela elinikezweOLT.

    I-ONUIzisetshenziswa

    Landela ngokugcwele i-IEEE 802.3/802.3ah

    ·Ithola ukuzwela kufika ku -25.5dBm

    ·Dlulisa amandla aze afike ku--1 ukuya ku-+4dBm

    ·I-PON isebenzisa i-fiber optical eyodwa ukuxhuma ku-OLT, bese kuthiOLTixhuma kuI-ONU. I-ONUihlinzeka ngezinsizakalo ezifana nedatha, i-IPTV (okungukuthi inethiwekhi yenethiwekhi yokuxhumana), izwi (lisebenzisa i-IAD, okungukuthi i-Integrated Access Device) nezinye izinsiza, ibona ngempela izinhlelo zokusebenza "zokudlala kathathu"

    ·Izinga eliphakeme kakhulu le-PON: i-symmetrical 1Gb/s idatha ekhuphukayo nephansi komfula, izwi le-VoIP nezinsizakalo zevidiyo ye-IP

    ·I-ONU"Plug futhi Dlala" ngokusekelwe ekutholeni okuzenzakalelayo nokucushwa

    ·Imisebenzi yekhwalithi ethuthukisiwe yesevisi (i-QoS) esekelwe ekushajweni kweleveli yesevisi (i-SLA).

    ·Amandla okuphatha akude asekelwa imisebenzi ye-OAM ecebile nenamandla

    ·Ukuthola ukukhanya okuzwelayo okuphezulu kanye nokusetshenziswa kwamandla okukhanya okokufaka okuphansi

    ·Sekela umsebenzi we-Diing Gasp
