PON optical module, yomwe nthawi zina imatchedwa PON module, ndi mawonekedwe apamwamba kwambiri omwe amagwiritsidwa ntchito mu machitidwe a PON (passive optical network).Amagwiritsa ntchito mafunde osiyanasiyana kuti atumize ndi kulandira zizindikiro pakatiOLT(Optical Line Terminal) ndiONT(Optical Network Terminal) molingana ndi ITU-T G.984.2 standard and multi-source agreement (MSA).Muyezo wamakono wamakampani ndi: downlink (OLT-ONU) ndikutumiza kutalika kwa 1490nm;uplink (ONU-OLT) ndikutumiza kutalika kwa 1310nm.
Kugwiritsa ntchito kwakukulu kwa PON Ethernet passive optical network sikungasiyanitsidwe ndi PON optical module chifukwa ndi gawo lofunikira la dongosolo la PON.Module ya PON makamaka imasintha chizindikiro chamagetsi cha OLT kukhala chizindikiro chowoneka bwino ndikuchitumiza ku ONU, pomwe uplink imatembenuza chizindikiro cha kuwala chosinthidwa ndiONUmu chizindikiro chamagetsi ndikuchitumiza kuOLT.Njira yotumizira ma fiber pakati pa OLT ndi ONU imakwaniritsidwa.
Gulu la ma module a PON: Pakadali pano, ma module a PON omwe amagwiritsidwa ntchito pamakampani amagawidwa m'mitundu iwiri yodziwika bwino:
GPON-Gigabit Passive Optical Network
EPON-Ethernet Passive Optical Network
Ngati mtengo suli chinthu, ndi bwino kusankha netiweki ya GPON kaye chifukwa ili ndi mautumiki ambiri komanso magwiridwe antchito abwino.
Zomwe zili pamwambazi ndi kufotokozera kwa PON gawo chidziwitso chakubweretserani ndi Shenzhen HDV photoelectric Technology Co., Ltd. The gawo mankhwala opangidwa ndi kampani chivundikirocho.Optical fiber modules, Ethernet modules, Optical fiber transceiver modules, optical fiber access modules, SSFP Optical modules,ndiSFP kuwala ulusi, etc. Zomwe zili pamwambazi zimatha kupereka chithandizo pazochitika zosiyanasiyana za intaneti.Gulu la akatswiri komanso lamphamvu la R&D litha kuthandiza makasitomala omwe ali ndi zovuta zaukadaulo, ndipo gulu loganiza bwino komanso laukadaulo litha kuthandiza makasitomala kupeza ntchito zapamwamba panthawi yokambirana zisanachitike komanso pambuyo popanga.Takulandirani kuLumikizanani nafepafunso lamtundu uliwonse.
