1) Mawu Oyamba:
Ndi kutuluka kwachangu kwa mabizinesi osiyanasiyana, mafakitale ochulukirapo amazindikira kuti ndikofunikira kudutsa "bottleneck" ya bandwidth posachedwa, ndipo kuwala kwa fiber ndi njira yabwino kwambiri yotumizira.Chingwe cha kuwala chili ndi zabwino ziwiri pa waya wamkuwa: mtunda wautali wotumizira;Zambiri zimatumizidwa nthawi imodzi (mpaka 100tbps / s pakadali pano).
Maphunzirowa makamaka amaphunzira zakumbuyo, malingaliro oyambira, mawonekedwe, momwe amagwiritsidwira ntchito ukadaulo wa GPON, kasamalidwe ka GPON system ndi njira yogawa mautumiki a terminal, komanso kugwiritsa ntchito maukonde ndi chitetezo cha intaneti cha GPON.
2) Lingaliro
PON ndi netiweki yowoneka bwino yokhala ndi mfundo mpaka mawonekedwe (p2mp);
GPON: Gigabit-catable passive Optical network.Mapangidwe a PON network: optical line terminal (OLT)
An optical distribution network (ODN) amapangidwa ndi optical splitter ndi optical fiber
Optical network unit/terminal onu/ont (optical network unit/optical network terminal)
Njira yopatsirana ili motere:
OLT uplink imalumikizidwa ndi intaneti, VoIP, IPTV, ndi downlink yolumikizidwa ku ODN;
ODN imagawira deta yonse ku ONU iliyonse kapena kupitirira kupyolera mu magawo a kuwala;
ONU kapena ont amasefa zomwe akufunikira kudzera pa chizindikiritso mu data frame, kenako ndikuzitumiza kwa wogwiritsa ntchito.
Zomwe zili pamwambazi ndi zomangamanga za GPON zobweretsedwa ndi Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd. Zomwe zimapangidwa ndi chivundikiro cha kampani. 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 ku Lumikizanani nafepafunso lamtundu uliwonse.
