Imodyuli ye-PON ye-optical module, ngamanye amaxesha ebizwa ngokuba yi-PON imodyuli, imodyuli ephezulu yokusebenza esetyenziswa kwiinkqubo ze-PON (i-passive optical network). Isebenzisa ubude bobude obuhlukeneyo ukuhambisa kunye nokufumana imiqondiso phakathiOLT(Optical Line Terminal) kunyeI-ONT(I-Optical Network Terminal) ngokuhambelana ne-ITU-T G.984.2 umgangatho kunye nesivumelwano semithombo emininzi (MSA). Umgangatho wangoku weshishini ngu: downlink (OLT-I-ONU) kukuhambisa umgama wamaza we-1490nm; ikhonkco eliphezulu (I-ONU-OLT) kukuhambisa umgama wamaza we-1310nm.
Ukusetyenziswa okubanzi kwe-PON Ethernet inethiwekhi ye-passive optical ayinakwahlulwa kwimodyuli ye-PON optical kuba iyinxalenye ebalulekileyo yenkqubo ye-PON. Imodyuli yePON ikakhulu iguqula umqondiso wombane weOLTkwimodyuli yesignali ye-optical kwaye iyidlulisele kwiI-ONU, ngelixa i-uplink iguqula umqondiso we-optical owenziwe yiI-ONUkwisignali yombane kwaye ayidlulisele kwiOLT. Indlela yokuhanjiswa kwefiber optical phakathi kweOLTkwaye iI-ONUyenzeka.
Ulwahlulo lweemodyuli zePON: Okwangoku, iimodyuli zePON ezisetyenziswa kushishino zohlulwe zibe ziintlobo ezimbini eziqhelekileyo:
I-GPON-Gigabit Passive Optical Network
I-EPON-Ethernet Passive Optical Network
Ukuba iindleko aziyonto, kungcono ukhethe inethiwekhi yeGPON kuqala kuba ineenkonzo ezibanzi kunye nokusebenza okungcono.
Oku kungasentla yingcaciso yolwazi lwemodyuli yePON eziziswe nguShenzhen HDV photoelectric Technology Co., Ltd. Iimveliso zemodyuli eziveliswe yikhava yenkampani.iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl. Ezi mveliso zemodyuli zingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi. Iqela le-R&D elinobuchule kunye nelomeleleyo linokunceda abathengi abanemiba yobugcisa, kwaye iqela leshishini elicingayo nelinobuchule linokunceda abathengi bafumane iinkonzo ezikumgangatho ophezulu ngexesha lokubonisana kwangaphambili kunye nomsebenzi wasemva kokuvelisa. Wamkelekile kuweQhagamshelana nathikulo naluphi na uhlobo lombuzo.
