1) Ijambo ry'ibanze:
Hamwe no kugaragara byihuse mubucuruzi butandukanye, inganda ninshi nizindi zimenya ko ari ngombwa guca "icyuho" cyumuvuduko mwinshi byihuse, kandi fibre optique nuburyo bwiza bwo kohereza.Fibre optique ifite ibyiza bibiri kurenza insinga z'umuringa: intera ndende yoherejwe;Amakuru menshi yoherezwa mugihe cyumwanya (kugeza 100tbps / s kurubu).
Aya masomo yiga cyane cyane ibyibanze, ibitekerezo byibanze, ibiranga, ibintu bikoreshwa muburyo bwa tekinoroji ya GPON, uburyo bwo kuyobora sisitemu ya GPON nuburyo bwo gukwirakwiza serivise ya terefone, hamwe no gukoresha imiyoboro hamwe nuburyo bwo kurinda imiyoboro ya GPON.
2) Igitekerezo
PON numuyoboro mwiza wa optique ufite ingingo yo kugwiza (p2mp);
GPON: Umuyoboro wa Gigabit ushoboye.Ibigize umuyoboro wa PON: umurongo wumurongo wa optique (OLT)
Umuyoboro wo gukwirakwiza optique (ODN) ugizwe na optique ya optique na fibre optique
Umuyoboro wa optique / terminal onu / ont (umuyoboro wa optique / umuyoboro wa optique)
Uburyo bwo kohereza ni ubu bukurikira:
OLT uplink ihujwe na enterineti, VoIP, IPTV, na downlink ihujwe na ODN;
ODN ikwirakwiza amakuru yose kuri buri ONU cyangwa ont binyuze muri optique igabana;
ONU cyangwa ont iyungurura amakuru bakeneye ikoresheje kode iranga murwego rwamakuru, hanyuma ikohereza kubakoresha.
Ibyavuzwe haruguru nububiko bwa GPON bwazanywe na Shenzhen Shenzhen HDV ifoto yamashanyarazi Ikoranabuhanga Co., Ltd. Ibicuruzwa bya module byakozwe nigifuniko cya sosiyete moderi ya fibre optique, Ethernet, optique fibre transceiver modules, optique ya fibre igera module, SSFP optique module, naSFP optique, nibindi bicuruzwa byavuzwe haruguru birashobora gutanga inkunga kubintu bitandukanye byurusobe.Itsinda ryinzobere kandi rikomeye R&D rirashobora gufasha abakiriya bafite ibibazo bya tekiniki, kandi itsinda ryubucuruzi ryatekereje kandi ryumwuga rirashobora gufasha abakiriya kubona serivise nziza mugihe cyo kubanziriza inama ndetse nakazi nyuma yumusaruro.Murakaza neza kuri twandikirekubibazo byose.
