Iyo optical splitter ndeimwe yeakakosha passive zvishandiso mune optical fiber link, uye inonyanya kuita basa rekutsemura.Iyo inowanzo shandiswa mutsetse yemagetsi terminal OLT uye optical network terminal ONU yeiyo passive optical network kuona iyo optical chiratidzo kupatsanura.
Iyo optical splitter inogovera iyo yakafambiswa optical chiratidzo mune imwe optical fiber kune akawanda optical fibers.Kune marudzi akawanda ekugovera, 1 × 2, 1 × 4, 1 × N, kana 2 × 4, M × N. Iyo general architecture yeFTTH ndeye: OLT (computer room office end) -ODN (passive optical network distribution distribution system ) -ONU (mushandisi wekupedzisira), umo iyo yekupatsanurwa kwemaziso inoshandiswa muODN kuona kuti vashandisi vekupedzisira vakawanda vanogovana imwe PON interface.Muchimiro chePON, kana kugoverwa kwezvivakwa kwakapararira uye kusingaenzaniswi, sekugoverwa kwevillas, chinhambwe chiri kure, uye kuwanda kwevashandisi kwakaderera, nzira yepakati yekuparadzanisa inogona kushandisa zvizere zviwanikwa uye kuvhara zvakatenderedza.
Chete kupatsanura kwemaziso kunogona kushandiswa mune passive optical network, kana akawanda optical splitters anogona kushandiswa pamwechete kupatsanura masaini masaini.
Zviratidzo zvekushanda zvinobata iyo optical splitter zvinowanzove zvinotevera:
Kuisa kurasikirwa
Kurasika kwekuisa kwefiber splitter kunoreva nhamba yedB yega yega inobuda inoenderana neiyo yekupinza yekurasikirwa kwemaziso.Kazhinji kutaura, idiki iyo yekuisa kurasikirwa kukosha.
Split ratio
Iyo kupatsanurwa reshiyo inotsanangurwa seyekubuda kwesimba reshiyo yega yega inobuda chiteshi che fiber splitter.Kazhinji, kupatsanurwa kwechiyero chePLC optical splitter inogovaniswa zvakaenzana, uye chiyero chekutsemura cheiyo fused tapered optical splitter inogona kusaenzana.Iyo chaiyo reshiyo yekumisikidza yeyero yekupatsanura ine hukama newavelength yechiedza chinofambiswa.Semuenzaniso, kana bazi remaziso richiendesa 1.31 micron chiedza, kupatsanurwa kwezvikamu zviviri zvinoguma zvinoguma 50:50;panguva yekufambisa 1.5μm chiedza, inova 70: 30 (Chikonzero nei izvi zvichiitika ndechokuti fiber splitter ine imwe bandwidth, kureva, bandwidth yechiratidzo chemaziso chinoparidzirwa apo chiyero chekuparadzanisa chinenge chisina kuchinjwa).
Kuiswa kwemurwere kwake ega
Isolation inoreva kugona kwekuzviparadzanisa kweimwe nzira yeoptical fiber splitter kubva kune masaini masaini mune dzimwe nzira dzemaziso.
Dzorera kurasikirwa
Kurasikirwa kwekudzoka, kunonziwo kuratidzira kurasikirwa, kunoreva kurasikirwa kwesimba kwechiratidzo chemaziso chakadzoka kana kuratidzwa nekusaenderera mberi mufiber kana mutsara wekutumira.Iyo yakakura kurasikirwa kwekudzoka, zviri nani, kuderedza kukanganiswa kwechiedza chinoratidzirwa pane mwenje sosi uye system.
Mukuwedzera, kufanana, kutungamira, PDL polarization kurasikirwa, nezvimwewo zvakare maparameter anokanganisa kushanda kweiyo optical splitter.Optical fiber splitter ndeimwe yeakanyanya kukosha passive midziyo mu optical fiber link, uye inonyanya kukodzera kubatanidza MDF uye terminal michina mune passive optical network (EPON, GPON, BPON, FTTX, FTTH, nezvimwewo) kugovera masaini masaini.
