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). Mulingo wapano wamakampani ndi: downlink (OLT-ONU) ndikutumiza kutalika kwa mawonekedwe a 1490nm; pamwamba (ONU-OLT) ndikutumiza kutalika kwa mafunde a 1310nm.
Kugwiritsa ntchito kwakukulu kwa PON Ethernet passive optical network sikungasiyanitsidwe ndi PON optical module chifukwa ndi gawo lofunikira la PON system. The PON module makamaka otembenuka magetsi chizindikiro chaOLTmu modulated kuwala siginecha ndikutumiza kwaONU, pamene uplink atembenuza chizindikiro cha kuwala kosinthidwa ndiONUmu chizindikiro chamagetsi ndikuchitumiza kuOLT. Njira yotumizira ma fiber optical pakati paOLTndiONUzimakwaniritsidwa.
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 chidziwitso cha gawo la PON chomwe chinakubweretserani ndi Shenzhen HDV photoelectric Technology Co., Ltd. Zinthu zomwe zimapangidwa ndi chivundikiro cha kampaniOptical 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.
