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 woshishino lwangoku: i-downlink (OLT-ONU) kukuhambisa i-wavelength ye-1490nm;i-uplink (ONU-OLT) kukuhambisa i-wavelength ye-1310nm.
Ukusetyenziswa okubanzi kwe-PON Ethernet inethiwekhi ye-passive optical ayinakwahlulwa kwi-PON imodyuli ye-optical kuba iyinxalenye ebalulekileyo yenkqubo ye-PON.Imodyuli ye-PON iguqula ubukhulu becala umqondiso wombane we-OLT kwi-modulated optical signal kwaye uyidlulisele kwi-ONU, ngelixa i-uplink iguqula i-optical signal modulated byI-ONUkwisignali yombane kwaye ayidlulisele kwiOLT.Indlela yokuhambisa i-fiber optical phakathi kwe-OLT kunye ne-ONU iyafezekiswa.
Ulwahlulo lweemodyuli zePON: Okwangoku, iimodyuli zePON ezisetyenziswa kushishino zohlulwe zibe ziindidi 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 elinobuchwephesha 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.
