Imodyuli ye-PON yimodyuli ephezulu yokusebenza kwe-optical esetyenziswa kwinkqubo ye-PON, Ebhekiselwa kuyo njengemodyuli ye-PON,Thobela i-ITU-T G.984.2 umgangatho kunye nesivumelwano semithombo emininzi (MSA),Isebenzisa ubude obuhlukeneyo bokuthumela kunye nokufumana iimpawu phakathi kweOLT (I-Optical Line Terminal) kunye ne-ONT (i-Optical Network Terminal).
Iindidi zeemodyuli zeGPON ezibonakalayo
GPON OLT B+
GPON OLT C+
GPON OLT C++
I-GPON OLT C++Eyongeziweyo
Iindidi zeemodyuli ze-EPON ezibonakalayo
EPON OLT PX20+
EPON OLT PX20++
I-EPON OLT PX20++Eyongeziweyo
Ngokubhekiselele kwi-bandwidth, ngaphezu kwe-100 megabits ye-bandwidth kunye nokufikelela kwe-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 xa kuthelekiswa nemodyuli yemveli
Imodyuli yePON yokubona
Imowudi yokuhanjiswa kwesignali ye-Optical: 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.
Imodyuli yemveli yokubona
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.
