    I-Rogue ONU yaba khona kanjani

    Isikhathi sokuthumela: Aug-08-2022

    Uhlelo lwe-PON lusebenzisa ubuchwepheshe bokuhlukanisa isikhathi sokuphindaphinda ekuqondeni kwe-uplink, kanyeI-ONUithumela ama-datagrams ekuqondeni kwe-uplink ngokwesitembu sesikhathi esinikezwe iOLT. Lapho iI-ONUikhipha ukukhanya ngaphandle kokunikeza isitembu sesikhathi, izongqubuzana nezimpawu zokukhishwa zenye i-onus, okuzothinta ukuxhumana okuvamile kwenye i-onus noma yonke i-onus. Isitembu sesikhathi sibonisa ukuthi isikhohlakaliI-ONUayithumeli amasignali abonakalayo phezulu.I-onus eqinile ihlukaniswe yaba izinhlobo ezimbili, eyodwa ukukhanya okungahleliwe kanti enye ukukhanya okude.Ukuqinisekisa ukusebenza okuvamile kwesistimu ye-PON futhi ugweme ukudideka ohlelweni ngenxa yokuvela kwe-onus enamandla ohlelweni. IHuawei inomsebenzi wokuthola ama-ONU akhohlakele. Lona umsebenzi kusistimu ye-PON ebheka amatheminali angakuthumeli ukukhanya ngesikhathi esifanele bese ewahlukanisa.

     

     

    i-rogue onu, yini i-rogue onu

     

     

     

    IsikhohlakaliI-ONUumsebenzi wokubona uhlanganisa izindlela ezimbili:

     

    1. OLTukutholwa

    Lapho i-OLTithola ukuphuma isikhathi esideI-ONU, ithumela umyalo wokuhlukanisa i-ONU ngokuya nge-ONU etholiwe. Ngokuvamile, i-OLTumsebenzi wokuthola usetshenziswa ekukhipheni isikhathi esideI-ONU, futhi kukhona iphutha elithile ekuhlonzweni kokukhipha okungahleliweI-ONU.Ngokuzenzakalelayo, iOLTicima iOLTumsebenzi wokuthola. Ngalesi sikhathi, i-OLTingathola ukuthi ingabe kukhona onus okhipha isikhathi eside kulayini we-PON. Kodwa-ke, ingahlulela kuphela ukuthi ingabe kukhona onus okhipha isikhathi eside ngaphansi kwembobo ye-PON, futhi ayikwazi ukuthola umsebenzi othile. Kufanele ithole i-onus eqinile ngokunqanyulwa kwefayibha esizeni.IOLTangakwazi ukubona okuqondileI-ONUekhipha ukukhanya ngaphansi kwembobo ye-PON futhi engakwazi ukulawula ukude ukuvala amandla okudlulisela e-I-ONUi-optical module; Umbandela ukuthi wonke ama-ONU angaphansi kwesixhumi esibonakalayo se-PON ayadingeka ukuze akwazi ukuhlaziya umlayezo we-downlink ploam futhi aphendule ngendlela efanele.

     

    2. I-ONUkancane

    Lapho i-I-ONUithola ukuphuma kokukhanya okude, izokwehlukanisa ngokuzenzakalela. Lo msebenzi ukwazi ukubona i-I-ONUngokukhishwa kokukhanya okude nokuphuma kokukhanya okungahleliwe.

    3. Imikhawulo yokuphatha inethiwekhi ekutholeni i-onus eqinile

    Ngokwalezi zimiso ezingenhla, abaphathi benethiwekhi badinga ukuhlangabezana nezimo ezimbili lapho bethola i-onus enzima. Enye iwukuthi umsebenzi wokuthola uvuliwe, kanti enye iwukuthi yonke i-onus ngaphansi kwembobo ye-PON ingahlaziya umlayezo we-downlink ploam futhi iphendule ngendlela efanele.

    Ngakho-ke, abaphathi benethiwekhi banethuba elithile lokuthola ngisho nokuhlonza ulwazi lwemishini yesikhohlakaliI-ONUokweqili eliphuma kudalaI-ONU, ebavumela ukuthi bathole indawoI-ONUindawo ehlanganiswe nokuphathwa kwempahla; Ku-onus ekhohlakele ekhipha ukukhanya ngezikhathi ezithile, ayikho indlela enhle yokuthola nokubeka i-onus.

    Indlela yokucubungula eyinhloko ye-onus ekhohlakele iseyisivivinyo sokudonsa isinyathelo ngesinyathelo ku-splitter ye-optical, ngakho-ke kubaluleke kakhulu ukuvuselela ulwazi lokuphathwa kwempahla.

     

    Okungenhla kuyincazelo yolwazi yokuthi “isikhohlakali sinjaniI-ONUyaba khona” elethwe kuwe ngabakwa-Shenzhen HDV photoelectric Technology Co., Ltd. Imikhiqizo yezokuxhumana ekhiqizwe yinkampani ihlanganisa;

    Izigaba zamamojula: amamojula we-fiber optical, Amamojula we-Ethernet, amamojula we-fiber optical transceiver, amamojula okufinyelela kwefiber optical, Amamojula we-SSFP optical, futhiImicu ye-Optical SFP, njll.I-ONUisigaba: EPON ONU, AC ONU, i-fiber optical ONU, I-CATV ONU, I-GPON ONU, XPON ONU, njll.

    OLTisigaba: Ukushintsha kwe-OLT, I-GPON OLT, I-EPON OLT, ukuxhumanaOLT, njll.

    Imikhiqizo yemojula engenhla ingahlinzeka ngosekelo lwezimo zenethiwekhi ezahlukahlukene. Ithimba le-R&D elichwepheshile neliqinile lingasiza amakhasimende anezinkinga zobuchwepheshe, futhi ithimba lebhizinisi elicabangayo nelichwepheshile lingasiza amakhasimende ukuthi athole amasevisi ekhwalithi ephezulu ngesikhathi sokubonisana kwangaphambilini nomsebenzi wangemuva kokukhiqiza. Siyakwamukela kuXhumana nathinganoma yiluphi uhlobo lombuzo.
