    Hlalutya ulwahlulo kunye neempawu zePON iimodyuli zamehlo

    Ixesha lokuposa: May-05-2020

    Imodyuli yePON yimodyuli ephezulu yokusebenza esetyenziswa kwinkqubo yePON, Ebizwa ngokuba yimodyuli yePON,Thobela i-ITU-T G.984.2 umgangatho kunye nesivumelwano semithombo emininzi (MSA),Isebenzisa ubude bamaza ahlukeneyo ukuthumela nokufumana iimpawu phakathiOLT(I-Optical Line Terminal) kunye ne-ONT (i-Optical Network Terminal).

    Ngokubhekiselele kwi-bandwidth, ngaphezu kwe-100 megabits ye-bandwidth kunye nokufikelela kwi-gigabit kuya kuba yinto eqhelekileyo.Ngokwethekhnoloji, i-10G PON iya kuba yinto ethandwa kakhulu. Ukongeza kwi-10G PON, abaqhubi nabo bakhuthaza ngenkuthalo inkqubela yeteknoloji yePON yesizukulwana esilandelayo.

     

    Iimpawu zePON imodyuli yokubona

    ◆ Iiprotokholi zokudluliselwa kweemodyuli ze-PON optical yi-APON (ATM PON), i-BPON (i-Broadband Passive Optical Network), i-EPON kunye ne-GPON. I-EPON kunye ne-GPON zisetyenziswa kakhulu ngoku.

    ◆ Unokuphepha ukuphazamiseka kwe-electromagnetic kunye nefuthe lombane kwisixhobo sangaphandle.

    ◆ Ukunciphisa izinga lokungaphumeleli kwemigca kunye nezixhobo zangaphandle, ukuphucula ukuthembeka kwenkqubo, kunye nokunciphisa iindleko zokugcina.

    Imodyuli yePON yokubona

    Imowudi yokudlulisa umqondiso we-Optical: i-point-to-multipoint (P2MP), iimodyuli azisetyenziswanga ngababini.

    Ilahleko yekhonkco yeFayibha: kubandakanya ukuthomalalisa, ukusasazwa, ukulahleka kokufaka unxibelelwano lwefayibha, njl.

    Umgama wothumelo: ngokubanzi ziikhilomitha ezingama-20.

    Isicelo: isetyenziswa ikakhulu kwinethiwekhi yofikelelo.

    Imowudi yokudluliselwa kwesignali ye-Optical: i-point-to-point (P2P), iimodyuli kufuneka zisetyenziswe ngababini.

    Ilahleko yekhonkco yeFayibha: kubandakanya ukuthomalalisa, ukusasazwa, ukulahleka kokufaka unxibelelwano lwefayibha, njl.

    Umgama wothumelo: ukuya kuthi ga kwi-160 yeekhilomitha.

    Isicelo: Isetyenziswa kakhulu kwinethiwekhi yomqolo.
