I-optical splitter ingenye yezinsiza ezibalulekile zokungenzi lutho kusixhumanisi se-fiber optical, futhi idlala kakhulu indima yokuhlukanisa.Ivamise ukusetshenziswa kutheminali yomugqa obonayo we-OLT kanye netheminali yenethiwekhi yokubona i-ONU yenethiwekhi ye-passive optical ukuze kubonakale ukuhlukana kwesignali yokubona.
I-optical splitter isakaza isignali ye-optical edlulisiwe ku-fiber optical eyodwa kuya kuma-multiple optical fibers.Kunezinhlobo eziningi zokusabalalisa, 1 × 2, 1 × 4, 1 × N, noma 2 × 4, M × N. Izakhiwo ezijwayelekile ze-FTTH yilezi: OLT (ukuphela kwehhovisi legumbi lekhompyutha) -ODN (uhlelo lokusabalalisa inethiwekhi ye-passive optical )-ONU (isiphetho somsebenzisi), lapho isihlukanisi esibonakalayo sisetshenziswa ku-ODN ukuze kuqashelwe ukuthi abasebenzisi abaningi bokugcina babelana ngesixhumi esibonakalayo se-PON esisodwa.Esakhiweni se-PON, lapho ukusatshalaliswa kwezakhiwo kuhlakazekile futhi kungajwayelekile, njengokusatshalaliswa kwezindlu zokuhlala, ibanga likude, futhi ukuminyana kwabasebenzisi kuphansi, indlela yokuhlukanisa emaphakathi ingakwazi ukusebenzisa ngokugcwele izinsiza futhi imboze okuzungezile.
Kungasetshenziswa isihlukanisi esisodwa kuphela kunethiwekhi ye-optical passive, noma izihlukanisi eziningi zokubona zingasetshenziswa ndawonye ukuze kuhlukaniswe amasignali abonakalayo.
Izinkomba zokusebenza ezithinta i-optical splitter ngokuvamile yilezi ezilandelayo:
Ukulahlekelwa kokufaka
Ukulahlekelwa kokufaka kwe-fiber splitter kubhekisela enanini le-dB lokukhipha ngakunye ngokuhlobene nokulahlekelwa kokubona okokufaka.Ngokuvamile, iba ncane inani lokulahlekelwa lokufaka.
Isilinganiso sokuhlukaniswa
Isilinganiso sokuhlukaniswa sichazwa njengesilinganiso samandla okukhiphayo wembobo ngayinye yokuphumayo yesihlukanisi sefayibha.Ngokuvamile, isilinganiso esihlukanisayo se-PLC esihlukanisayo esibonakalayo sisakazwa ngokulinganayo, futhi isilinganiso sokuhlukanisa se-fused tapered optical splitter singase singalingani.Ukusethwa kwesilinganiso okucacisiwe kwesilinganiso sokuhlukanisa kuhlobene nobude begagasi bokukhanya okudlulisiwe.Isibonelo, uma igatsha le-optical lidlulisa ukukhanya kwe-micron engu-1.31, isilinganiso sokuhlukanisa semikhawulo emibili yokuphumayo singu-50:50;lapho uthumela i-1.5μm ukukhanya, kuba ngu-70: 30 (Isizathu sokuthi kungani lokhu kwenzeka kungenxa yokuthi i-fiber splitter inomkhawulokudonsa othile, okungukuthi, umkhawulokudonsa wesignali ye-optical odluliswa lapho isilinganiso sokuhlukaniswa singaguquki ngokuyisisekelo).
Ukuzihlukanisa
Ukuzihlukanisa kusho ikhono lokuzihlukanisa lendlela eyodwa yokubona ye-optical fibre splitter kusukela kumasignali okubona kwezinye izindlela zokubona.
Buyisela ukulahlekelwa
Ukulahlekelwa kwembuyiselo, okubuye kubizwe ngokuthi ukulahlekelwa kokubona, kubhekisela ekulahlekelweni kwamandla esignali yokubona ebuyisiwe noma okuboniswa ukungaqhubeki ku-fiber noma ulayini wokudlulisela.Ukulahlekelwa okukhulu kwembuyiselo, kungcono, ukunciphisa umthelela wokukhanya okubonakalayo kumthombo wokukhanya nesistimu.
Ukwengeza, ukufana, ukuqondisa, ukulahlekelwa kwe-PDL polarization, njll nakho kuyimingcele ethinta ukusebenza kwe-optical splitter.I-Optical fibre splitter ingenye yezisetshenziswa ezibaluleke kakhulu ze-passive kusixhumanisi se-fiber optical, futhi ifaneleka ngokukhethekile ukuxhuma i-MDF nemishini yokugcina kumanethiwekhi optical passive (EPON, GPON, BPON, FTTX, FTTH, njll.) ukusabalalisa amasignali optical.
