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. Hangata e sebelisoa ho optical line terminalOLTle terminal ea marang-rang ea opticalONUea passive optical network ho hlokomela ho petsoha ha lets'oao la 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. Mehaho e akaretsang ea FTTH ke:OLT(qetello ea ofisi ea kamore ea k'homphieutha) -ODN (mokhoa oa ho tsamaisa marang-rang oa passive optical) -ONU(Qetellong ea mosebelisi), moo optical splitter e sebelisoang 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 kabo ea li-villas, sebaka se hole, mme palo ea basebelisi e tlase, mokhoa oa ho arola o bohareng o ka sebelisa lisebelisoa ka botlalo mme o koahele 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, karolelano ea ho arohana ha likarolo tse peli tse hlahisoang ke 50:50; ha o fetisetsa 1.5μm leseli, 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 lets'oao la optical e fetisetsoang ha karohano ea karohano 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 haholo ho hokela MDF le lisebelisoa tsa terminal ho marang-rang a passive optical.EPON, GPON, BPON, FTTX, FTTH, joalo-joalo) ho aba mats'oao a mahlo.
