Muri iki gihe, hamwe no gukomeza gutezimbere no kuzamura optique ya fibre optique, PON (umuyoboro wa optique fibre optique) wabaye inzira yingenzi yo gutwara umurongo mugari wa serivise. PON igabanijwemo GPONnaEPON. GPON irashobora kuvugwa ko ari verisiyo igezweho ya EPON. Iyi ngingo, etu-ihuza, irakuzanira gusobanukirwa na GPON optique module.
Mbere ya byose, tekinoroji ya GPON iruta EPON mubijyanye no gukoresha umurongo mugari, ikiguzi, inkunga ya serivisi nyinshi, imikorere ya OAM nibindi bice. GPON ikoresha kode yo gutombora nkumurongo wumurongo, gusa uhindura code utarinze kode, kubwibyo rero nta gihombo cyagutse. Ukurikije igiciro kimwe, igiciro ni gito hamwe nigipimo cyihuta cya Gigabit. Bitewe nuburyo bwihariye bwo gupakira, burashobora gushyigikira serivisi za ATM na serivisi za IP. OAM ikungahaye ku makuru, harimo gutanga uruhushya rwogutanga uruhushya, kugabura kwaguka (DBA), kugenzura guhuza, guhinduranya kurinda, guhanahana urufunguzo, hamwe nibikorwa bitandukanye byo gutabaza.
Sisitemu ya GPON optique module isabwa igabanijwe mubice bitatu: A, B, na C. Ibipimo bya optique bya buri rwego biratandukanye. Kugeza ubu, igabanijwemo cyane mu byiciro b + na c +. Kwakira imbaraga zingana zaONUuruhande muri rusange hafi ya 1-2dBm munsi yi yaOLTruhande. Itandukaniro niryo rikurikira:
Igikorwa nyamukuru cyaGPON ONU module ya optique ni iyo kwakira no gusohora urumuri, ibyo bikaba bigaragazwa na laser, guhindura ibimenyetso byamashanyarazi byahinduwe mubimenyetso bya optique hanyuma ukabishyira mumurongo wa fibre optique kugirango wohereze. Uwakiriye yakira urumuri, akongerera urumuri rwakiriwe akaruhindura ikimenyetso cyamashanyarazi kuri sisitemu yo gutunganya ibimenyetso kugirango abone amakuru yingirakamaro. Ubwoko bwa paki ni SFP, interineti ya SC, igipimo cyo kohereza ni 1.25g / 2.5g, intera yoherejwe irashobora kugera kuri 20km. Uburebure bwikwirakwizwa ni 1310nm naho uburebure bwakirwa ni 1490nm. Imikorere yo kwisuzumisha ya DDM irashyigikiwe, kandi ubushyuhe bwakazi bwurwego rwubucuruzi (0 ° C - 70 ° C) nicyiciro cyinganda (-40 ° C - +85 ° C) birashoboka.
GPON OLT module optique yapakiwe hamwe na SFP, interineti ya SC, igipimo cya 2.5g / 1.25g, intera yohereza 20km, uburebure bwa 1490nm, uburebure bwa 1310nm, hamwe nubufasha bwibikorwa bya DDM byo gusuzuma, bigatuma bikwiranye numurongo wa optique.
Ibyavuzwe haruguru nubusobanuro bwubumenyi bwa GPON optique yazanwe na Shenzhen HDV ifoto yumuriro wa tekinoroji Co., Ltd. Ibicuruzwa bya module byakozwe nigifuniko cya sosiyete moderi ya fibre optique, Ethernet, optique fibre transceiver modules, optique ya fibre optique, SSFP optique module, naSFP optique, nibindi bicuruzwa byavuzwe haruguru birashobora gutanga inkunga kubintu bitandukanye byurusobe. Itsinda ryumwuga 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 kubanza kugisha inama no gukora nyuma yumusaruro. Murakaza neza kuri twandikire kubibazo byose.
