Nyob rau hauv niaj hnub optical networktyplogies, lub advent ntawmfiber ntau optic splittertxhawb pab cov neeg siv kom ua tau zoo tshaj plaws ntawm kev ua haujlwm ntawm optical network circuits.Fiber optic splitter, tseem hu ua optical splitter, los yog beam splitter, yog ib qho kev sib xyawyoj-qhiaoptical fais fab kev faib khoom uas tuaj yeem faib qhov teeb meem teeb pom kev zoo rau hauv ob lossis ntau lub teeb kab teeb, thiab rov ua dua, muaj ntau qhov kev tawm tswv yim thiab tso tawm.Optical splitter tau ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus kho qhov muag (xws li EPON, GPON, BPON, FTTX, FTTH, thiab lwm yam) los ntawm kev tso cai rau ib qho PON interface los koom nrog ntau tus neeg siv khoom.
Fiber Optic Splitter ua haujlwm li cas?
Feem ntau hais lus, thaum lub teeb teeb liab xa mus rau hauv ib hom fiber ntau, lub teeb lub zog tsis tuaj yeem ua tiav hauv cov tub ntxhais fiber ntau.Ib qho me me ntawm lub zog yuav kis tau los ntawm cladding ntawm fiber ntau.Qhov ntawd yog hais tias, yog tias ob lub fibers ze txaus rau ib leeg, lub teeb xa hluav taws xob hauv ib qho khoom siv kho qhov muag tuaj yeem nkag mus rau lwm qhov fiber ntau.Yog li ntawd, cov txheej txheem kev hloov pauv ntawm cov teeb liab kho qhov muag tuaj yeem ua tiav hauv ntau lub fibers, uas yog li cas fiber optic splitter los ua.
Tshwj xeeb hais lus, lub passive optical splitter tuaj yeem sib cais, lossis cais, qhov teeb meem teeb pom kev zoo rau hauv ob peb lub teeb teeb ntawm ib qho piv txwv.Lub 1 × 4 phua configuration nthuav tawm hauv qab no yog cov qauv hauv qab no: sib cais qhov teeb meem teeb pom kev zoo los ntawm ib qho khoom siv fiber ntau rau hauv plaub lub teeb teeb thiab xa lawv los ntawm plaub tus neeg tso tawm fiber ntau cables.Piv txwv li, yog hais tias tus input fiber optic cable nqa 1000 Mbps bandwidth, txhua tus neeg siv thaum kawg ntawm cov zis fiber cables siv tau lub network nrog 250 Mbps bandwidth.
Lub optical splitter nrog 2 × 64 phua configurations yog me ntsis nyuab dua li 1 × 4 phua configurations.Muaj ob lub input terminals thiab rau caum-plaub cov zis terminals nyob rau hauv lub optical splitter nyob rau hauv 2 × 64 phua configurations.Nws txoj haujlwm yog cais ob qhov teeb meem teeb pom kev zoo los ntawm ob tus tib neeg cov khoom siv fiber ntau rau hauv rau caum-plaub lub teeb kab teeb thiab xa lawv los ntawm rau caum-plaub lub teeb ib tus neeg tso zis fiber ntau cables.Nrog rau kev loj hlob sai ntawm FTTx thoob ntiaj teb, qhov yuav tsum tau muaj kev sib cais loj dua hauv cov tes hauj lwm tau nce los pab cov neeg siv khoom loj.
Fiber Optic Splitter Hom
Classified los ntawm Pob Style
Qhov kho qhov muagsplitterstuaj yeem raug txiav nrog ntau hom kev sib txuas, thiab cov pob thawj tuaj yeem yog lub thawv hom lossis hom raj stainless.Fiber optic splitter lub thawv feem ntau yog siv nrog 2 hli los yog 3 hli txheej txoj kab uas hla cable, thaum lwm yam yog feem ntau siv ua ke nrog 0.9 hli txheej kab.Tsis tas li ntawd, nws muaj ntau qhov sib txawv sib txawv, xws li 1 × 2, 1 × 8, 2 × 32, 2 × 64, thiab lwm yam.
Classified los ntawm Transmission Medium
Raws li qhov sib txawv kis nruab nrab, muaj ib hom optical splitter thiab multimode optical splitter.Multimode optical splitter txhais tau hais tias cov fiber ntau yog optimized rau 850nm thiab 1310nm lag luam, whereas tib hom ib tug txhais tau tias cov fiber ntau optimized rau 1310nm thiab 1550nm lag luam.Dhau li ntawd, raws li kev ua haujlwm wavelength sib txawv, muaj ib lub qhov rais thiab dual qhov rais optical splitters - lub qub yog siv ib tug ua hauj lwm wavelength, thaum lub tom kawg fiber optic splitter yog nrog ob ua hauj lwm wavelengths.
Classified los ntawm Kev Tsim Khoom
FBT splitter yog raws li cov cuab yeej siv niaj hnub los txuas ob peb fibers ua ke los ntawm sab ntawm fiber ntau, uas muaj cov nqi qis dua.PLC splittersyog raws li kev siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob, uas muaj ntau yam sib faib, suav nrog 1: 4, 1: 8, 1: 16, 1: 32, 1: 64, thiab lwm yam, thiab tuaj yeem muab faib ua ntau hom xws li liab qabPLC splitter, blockless PLC splitter, ABS splitter, LGX lub thawv splitter, fanout PLC splitter, mini plug-in hom PLC splitter, thiab lwm yam.
Xyuas cov nram qab no PLC Splitter vs FBT Splitter Sib Piv Daim Ntawv Qhia:

Fiber Optic Splitter Daim Ntawv Thov hauv PON Networks
Optical splitters, ua kom lub teeb liab ntawm qhov muag fiber ntau faib ntawm ob lossis ntau dua optical fibers nrog kev sib cais sib txawv (1 × N lossis M × N), tau siv dav hauv PON tes hauj lwm.FTTH yog ib qho ntawm cov txheej txheem kev thov.Ib tug raug FTTH architecture yog: Optical Line Terminal (OLT) nyob rau hauv lub hauv paus chaw ua hauj lwm;Optical Network Unit (ONU) nyob ntawm tus neeg siv kawg;Optical Distribution Network (ODN) tau nyob nruab nrab ntawm ob qho dhau los.Ib qho optical splitter feem ntau siv hauv ODN los pab ntau tus neeg siv kawg sib koom PON interface.
Point-to-multipoint FTTH network xa tawm tuaj yeem muab faib ntxiv rau hauv nruab nrab (ib-theem) lossis cascaded (ntau-theem) splitter configurations nyob rau hauv qhov faib ntawm FTTH network.Kev teeb tsa hauv nruab nrab feem ntau siv qhov sib faib ua ke ntawm 1: 64, nrog rau 1: 2 splitter nyob rau hauv lub hauv paus chaw ua hauj lwm, thiab ib tug 1: 32 nyob rau hauv ib tug sab nraum nroj tsuag (OSP) enclosure xws li lub txee.Ib tug cascaded los yog faib splitter configuration ib txwm tsis muaj splitters nyob rau hauv lub hauv paus chaw ua hauj lwm.Qhov chaw nres nkoj OLT txuas nrog / spliced ncaj qha mus rau sab nraud cog fiber ntau.Thawj theem ntawm kev sib cais (1: 4 lossis 1: 8) yog ntsia rau hauv qhov kaw, tsis deb ntawm lub hauv paus chaw ua haujlwm;theem ob ntawm splitters (1:8 los yog 1:16) yog nyob rau ntawm lub thawv davhlau ya nyob twg, ze rau cov neeg siv khoom thaj chaw.Centralized Splitting vs Distributed Spliting nyob rau hauv PON Raws li FTTH Networks yuav ntxiv qhia txog ob txoj kev sib cais uas siv fiber ntau optic splitters.
Yuav Ua Li Cas Xaiv Txoj Cai Fiber Optic Splitter?
Feem ntau, qhov zoo tshaj plaws fiber ntau optic splitter yuav tsum tau dhau los ntawm kev sim nruj heev.Cov ntsuas kev ua tau zoo uas yuav cuam tshuam rau fiber ntau optic splitter yog raws li hauv qab no:
Insertion poob: Hais txog dB ntawm txhua qhov tso zis txheeb ze rau qhov tsis pom kev pom.Nquag, qhov me me ntawm qhov poob qis, qhov kev ua tau zoo ntawm lub splitter.
Rov qab poob: Kuj hu ua kev xav poob, yog hais txog lub zog poob ntawm lub teeb liab kho qhov muag uas rov qab los yog cuam tshuam vim qhov tsis sib xws hauv fiber ntau lossis kab sib kis.Feem ntau, qhov loj dua qhov rov qab poob, qhov zoo dua.
Spliting ratio: txhais raws li cov zis hluav taws xob ntawm lub qhov hluav taws xob splitter qhov chaw nres nkoj hauv daim ntawv thov system, uas muaj feem xyuam rau lub wavelength ntawm lub teeb kis.
Kev rho tawm: Qhia txog lub teeb pom kev pom kev sib cais rau lwm txoj hauv kev kho qhov muag ntawm cov teeb liab optical cais.
Tsis tas li ntawd, kev sib luag, kev coj ncaj ncees, thiab PDL polarization poob kuj tseem ceeb heev uas cuam tshuam rau kev ua haujlwm ntawm cov nqaj hlau splitter.
Rau cov kev xaiv tshwj xeeb, FBT thiab PLC yog ob qho kev xaiv tseem ceeb rau feem coob ntawm cov neeg siv.Qhov sib txawv ntawm FBT splitter vs PLC splitter feem ntau yog nyob rau hauv kev khiav hauj lwm wavelength, splitting ratio, asymmetric attenuation ib ceg, tsis ua hauj lwm tus nqi, thiab lwm yam. Hais lus hais, lub FBT splitter yog suav hais tias yog ib tug nqi-zoo tshuaj.PLC splitter featuring zoo saj zawg zog, siab stability, tsis ua hauj lwm tus nqi, thiab dav kub ntau yam yuav siv tau nyob rau hauv high-density daim ntaub ntawv.
Rau cov nuj nqis, cov nqi ntawm PLC splitters feem ntau siab dua FBT splitter vim yog cov cuab yeej tsim khoom nyuaj.Hauv kev teeb tsa tshwj xeeb, kev teeb tsa sib cais hauv qab 1 × 4 raug qhia kom siv FBT splitter, thaum cais cov teeb tsa saum toj 1 × 8 raug pom zoo rau PLC splitters.Rau ib zaug lossis dual wavelength kis tau tus mob, FBT splitter tuaj yeem txuag nyiaj.Rau PON broadband kis tau tus mob, PLC splitter yog ib qho kev xaiv zoo dua xav txog yav tom ntej nthuav dav thiab saib xyuas cov kev xav tau.
Cov lus xaus
Fiber optic splitters pab kom lub teeb liab ntawm ib qho khoom siv kho qhov muag kom muab faib rau ntawm ob lossis ntau dua fibers.Txij li cov splitters tsis muaj cov khoom siv hluav taws xob thiab tsis xav tau lub zog, lawv yog ib qho tseem ceeb thiab siv dav hauv feem ntau cov fiber-optic tes hauj lwm.Yog li, xaiv fiber ntau optic splitters los pab txhawb kev siv cov khoom siv kho qhov muag kom zoo yog qhov tseem ceeb rau kev tsim lub network architecture uas yuav kav ntev mus rau yav tom ntej.
