Optical splitter ke e 'ngoe ea lisebelisoa tsa bohlokoa tse sa sebetseng ho sehokelo sa fiber optical, mme haholo-holo e bapala karolo ea ho petsoha.Ka kakaretso e sebelisoa ho optical line terminal OLT le optical network terminal ONU ea passive optical network ho lemoha ho arohana ha pontšo ea optical.
Optical splitter e aba lets'oao le fetisitsoeng la optical ka fiber e le 'ngoe ea optical ho li-multiple optical fibers.Ho na le mefuta e mengata ea kabo, 1 × 2, 1 × 4, 1 × N, kapa 2 × 4, M × N. Sebopeho se akaretsang sa FTTH ke: OLT (qetellong ea ofisi ea kamore ea k'homphieutha) -ODN (mokhoa oa ho tsamaisa marang-rang oa passive optical ) -ONU (qetellong ea mosebelisi), moo ho kenngoa ha optical splitter ho ODN ho hlokomela hore basebelisi ba bangata ba ho qetela ba arolelana sebopeho se le seng sa PON.Ka sebopeho sa PON, ha kabo ea meaho e hasane ebile e sa tloaeleha, joalo ka ho ajoa ha li-villas, sebaka se hole, 'me palo ea basebelisi e tlase, mokhoa oa ho arola o bohareng o ka sebelisa lisebelisoa ka botlalo le ho koahela libaka tse potolohileng.
Ke karolo e le 'ngoe feela ea optical e ka sebelisoang marang-rang a marang-rang, kapa li-splitter tse ngata tsa optical li ka sebelisoa hammoho ho arola matšoao a optical.
Matšoao a ts'ebetso a amang optical splitter hangata ke a latelang:
tahlehelo ea ho kenya
Tahlehelo ea ho kenngoa ha fiber splitter e bolela palo ea dB ea sehlahisoa se seng le se seng se amanang le tahlehelo ea optical e kenang.Ka kakaretso, palo ea tahlehelo ea ho kenya e nyane.
Karolelano ea ho arohana
Karolelano e arohaneng e hlalosoa e le karo-karolelano ea matla a tlhahiso ea koung ka 'ngoe ea phallo ea fiber.Ka kakaretso, karo-karolelano e arohaneng ea PLC ea optical splitter e ajoa ka ho lekana, 'me karolelano e arohaneng ea "fused tapered optical splitter" e ka se lekane.Sebaka se khethehileng sa karo-karolelano ea karo-karolelano ea ho arohana e amana le bolelele ba maqhubu a leseli le fetisitsoeng.Ka mohlala, ha lekala la optical le fetisa leseli la 1.31 micron, karo-karolelano ea ho arohana ha likarolo tse peli tse hlahisoang ke 50:50;ha o fetisetsa 1.5μm khanya, e fetoha 70: 30 (Lebaka leo ka lona sena se etsahalang ke hobane fiber splitter e na le bandwidth e itseng, ke hore, bandwidth ea pontšo ea optical e fetisetsoang ha karolelano ea ho arohana e sa fetohe).
Ho behwa ka thoko
Ho itšehla thajana ho bolela bokhoni ba ho itšehla thajana ba tsela e le 'ngoe ea optical fiber splitter ho tloha lipontšong tsa optical litseleng tse ling tsa optical.
Khutlisetsa tahlehelo
Tahlehelo ea ho khutla, eo hape e bitsoang tahlehelo ea ho bonahatsa, e bolela ho lahleheloa ke matla a lets'oao la optical le khutliselitsoeng kapa ho bonts'oa ke ho se tsoelepele ho faeba kapa mohala oa phetiso.Ha tahlehelo ea ho khutla e kholoanyane, ho molemo, ho fokotsa tšusumetso ea leseli le hlahang mohloling oa leseli le tsamaiso.
Ho phaella moo, ho tšoana, ho tsamaisana, ho lahleheloa ke polarization ea PDL, joalo-joalo le tsona ke litekanyo tse amang ts'ebetso ea optical splitter.Optical fiber splitter ke e 'ngoe ea lisebelisoa tsa bohlokoa ka ho fetesisa tsa sehokelo sa fiber optical,' me e loketse ka ho khetheha bakeng sa ho hokahanya MDF le lisebelisoa tsa terminal ho marang-rang a passive optical (EPON, GPON, BPON, FTTX, FTTH, joalo-joalo) ho aba mats'oao a mahlo.
