1) Intshayelelo:
Ngokuvela ngokukhawuleza kwamashishini ahlukeneyo, amashishini amaninzi nangaphezulu ayaqonda ukuba kuyimfuneko ukukrazula "i-bottleneck" ye-bandwidth ngokukhawuleza, kwaye i-fiber optical iyona ndlela ehamba phambili yokuhambisa.Ifayibha ye-Optical ineenzuzo ezimbini ngaphezulu kocingo lobhedu: umgama omde wothumelo;Idatha eyongezelelweyo ihanjiswa ngexesha leyunithi (ukuya kuthi ga kwi-100tbps / s okwangoku).
Le khosi ifunda ubukhulu becala imvelaphi, iikhonsepthi ezisisiseko, iimpawu, iimeko zesicelo sobuchwepheshe be-GPON, indlela yolawulo yenkqubo ye-GPON kunye nemowudi yokuhanjiswa kwenkonzo ye-terminal, kunye nesicelo sothungelwano kunye nemo yokukhusela inethiwekhi yeGPON.
2) Ingcamango
I-PON yinethiwekhi ye-optical passive ene-point to multipoint (p2mp) isakhiwo;
I-GPON: Inethiwekhi ye-Gigabit ekwaziyo ukugqitha.Ukuqulunqwa kwePON womnatha womnatha: iterminal yomgca wokubona (OLT)
Inethiwekhi yokusabalalisa optical (ODN) yenziwe nge-optical splitter kunye nefiber optical
Iyunithi yothungelwano olubonayo/isiphelo se-onu/ont (iyunithi yenethiwekhi yokubona/ i-terminal yenethiwekhi yokubona)
Inkqubo yogqithiso imi ngolu hlobo lulandelayo:
I-OLT uplink ixhunyiwe kwi-Intanethi, i-VoIP, i-IPTV, kunye ne-downlink ixhunywe kwi-ODN;
I-ODN ihambisa yonke idatha kwi-ONU nganye okanye i-ont ngokusebenzisa ulwahlulo lwamehlo;
I-ONU okanye i-ont ihluza idatha abayidingayo ngekhowudi yokuchonga kwisakhelo sedatha, kwaye emva koko idlulisele kumsebenzisi.
Oku ngasentla luyilo lwenethiwekhi yeGPON eziswe yi-Shenzhen Shenzhen 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 kuwe qhagamshelana nathikulo naluphi na uhlobo lombuzo.
