Fiber Ntau Splitter Rau Passive Optical Network
Fiber splitter , kuj tseem hu ua beam splitter, yuav siv ib qho xov tooj hluav taws xob optics teeb liab thiab faib nws mus rau ntau lub cim. Nws yog siv los faib tawm ib qho nqaj ntawm optical fiber lub teeb rau hauv ntau qhov sib txawv ntawm qhov sib piv, piv txwv li, 1X4 LC hom sib npaug sib cais sib npaug fiber ntau optic splitter tuaj yeem faib cov hluav taws xob optic teeb liab ua plaub sib npaug 25% thiab xa mus rau 4 sib txawv raws.
Raws li ua haujlwm wavelength qhov sib txawv muaj tib lub qhov rais thiab dual lub qhov rais fiber ntau optic splitters Thiab muaj tib hom fiber ntau splitter thiab multimode fiber splitters. Cov pa hluav taws xob txuas rau ntawm cov hluavtaws fiber ntau yog FC lossis SC hom. Cov thawv ntim hluav taws xob tsis muaj hluav taws xob thiab siv tsis muaj zog. Lawv yog lub network cov ntsiab lus uas muab tso rau hauv Qhov Tshaj Lij Chib Passive Optical Network thiab muaj nyob rau ntau qhov sib txawv ntawm cov sib piv, suav nrog 1: 8, 1:16, thiab 1:32.
Feem ntau hom fiber ntau-qhov cuam tshuam splitter tawm cov khoom sib txig sib luag, nrog ib nrab lub teeb liab mus rau ib txhais ceg ntawm cov zis thiab ib nrab mus rau lwm yam. Nws yog qhov ua tau kom tau cov splitters uas siv sib cais sib faib, tso cov nyiaj ntau dua ntawm lub teeb liab mus rau ib sab ntawm splitter dua li lwm qhov. Cov khoom sib cais tau qhia nrog tus lej uas sawv cev rau lub teeb liab faib, xws li 50/50 yog tias qhov sib cais txawm yog, lossis 80/20 yog tias 80% ntawm lub teeb liab mus rau ib sab thiab tsuas yog 20% rau sab nraud.
Qee hom fiber ntau-qhov cuam tshuam tau yeej tuaj yeem ua haujlwm hauv ob qhov kev coj ua. Qhov no txhais tau hais tias yog tias cov cuab yeej raug teeb tsa nyob rau hauv ib txoj kev, nws ua raws li kev cais tawm thiab faib cov teeb liab nkag ua ob ntu, xa tawm ob qhov tshwm sim tawm. Yog tias nws raug ntsia rau hauv thim rov qab, nws ua raws li tus coupler, coj ob qho kev nkag mus thiab coj lawv mus rau hauv ib qho kev tawm. Txawm hais tias lub tshuab hluav taws xob sib xyaw ua ke sib xyaw hauv cov kev taw qhia sab saum toj los yog faib cov teeb hluav taws xob hauv qhov kev coj hauv qab, nws tseem qhia txog qhov teeb meem zoo ib yam rau lub teeb liab tawm tswv yim (ib qho me ntsis ntau dua 3 dB rau txhua 1: 2 sib faib).
Fiber Optic Splitter Nta:
Ib Hom, multimode, thiab PM fiber ntau hom;
Ntau lub chaw nres nkoj teeb tsa, kev cai ntev thiab cable diameters;
Ntau cov kev faib tau sib txawv, 50:50 txog 1:99;
Tube hom lossis Box hom, PLC splitter los yog Fused fiber ntau optic splitter;
PC, UPC, thiab APC fiber ntau kho qhov txuas;
Muaj nrog FC, SC, ST, LC, thiab MU cov khoom sib txuas.
Fiber optic splitter, yog ib qho tseem ceeb tshaj dhau los hauv qhov txuas hluav taws xob fiber ntau, yog cov twj siv hluav taws xob optical tandem nrog ntau lub tswv yim nkag mus thiab ntau cov chaw nres tsheb tawm. Tshwj xeeb tshaj yog thov rau passive optical network (EPON, GPON, BPON, FTTX, FTTH thiab lwm yam) los txuas MDF thiab cov khoom siv davhlau ya nyob twg thiab kom ua tiav lub ceg ntawm lub teeb liab kho qhov muag.
Passive Optical Network PON splitters ua lub luag haujlwm tseem ceeb hauv Fiber rau Lub Tsev (FTTH) tes hauj lwm los ntawm kev tso cai PON network nkaus xwb los sib koom nrog ntau tus neeg siv. Ib lub PON network yuav raug tsim nrog ib lub tshuab hluav taws xob uas muaj qhov sib cais, lossis nws tuaj yeem muaj ob lossis ntau qhov chaw sib cais ua ke. Txij li thaum txhua qhov txuas sib txuas ntxiv cov yeeb yaj kiab sib txuas, ib qho kev sib cais ib leeg zoo dua rau ntau qhov kev sib tsoo ua ke. Ib qho txuas txuas ntxiv (thiab cov peev xwm) tau qhia rau hauv kev sib txuas ntawm ob txoj kev sib cais ua ke.
Ib qho kev sib faib ib leeg kuj tseem siv tau hauv GPON network. Nco ntsoov tias lub tshuab nqus khoom tuaj yeem xa mus hauv Lub Chaw Saib Xyuas Nruab Nrab (CO) nyob nrog OLT, lossis nws yuav raug muab tso rau hauv Chav Sab Nraud Sab Ntiaj Teb (OSP) txee ze dua rau cov neeg yuav khoom. Dab tsi ntxiv, A splitter tuaj yeem muab tso rau hauv qab daus ntawm lub tsev rau ntau Chav Tsev (MDU) kev teeb tsa.
