Dab Tsi Yog Fiber Optic Splitter?
Lub fiber ntau optic splitter tseem raug xa mus rau qhov optical splitter, uas yog ib qho kev siv hluav taws xob ntawm lub tshuab fais fab ntawm hluav taws xob. Nws plays lub luag hauj lwm tseem ceeb hauv kev siv kho qhov muag pom zoo (EPON, GPON, BPON, FTTX, FTTH thiab lwm yam) los ntawm kev cia ib tus PON interface mus koom nrog ntau tus neeg yuav khoom. Ua kom tau qhov no, nws yog tsim los faib cov teeb meem ntawm lub teeb nrig rau ob lossis ntau tshaj kab teeb ci thiab ob peb lub teeb kab teeb rau lub chaw faib khoom raws li ib qho khoom siv fibre ntau qhov muag, uas muaj nuj nqi los ua kom qhov kev ua tau zoo ntawm cov kev sib tham network.
Yuav Ua Li Cas Optical Splitter?
Feem ntau, ib qho chaw kho qhov muag tau muaj ntau lub tswv yim thiab tso tawm cov khoom siv los ua tus ceg ntawm lub teeb kab thiab ua kom zoo tshaj qhov ua haujlwm ntawm qhov kho qhov muag network. Qhov kev kho qhov muag pom tau zoo tuaj yeem faib, lossis cais, qhov teeb meem ntawm lub teeb nrig rau ob peb lub teeb kab ntawm ib qho kev sib piv. Raws li ib qho piv txwv yooj yim, Daim Duab Qhia 1 qhia tau hais tias qhov kev kho qhov muag zoo li cas nrog 1 x 4 phom muaj peev xwm muab cais tawm ntawm ib qho teeb meem ntawm lub teeb pom kev ntawm fiber ntau rau hauv plaub lub teeb kab thiab xa lawv mus rau plaub lub tshuab hluav taws xob. Piv txwv li, yog tias cov lus siv fiber optic cable nqa 1000 Mbps bandwidth, txhua tus neeg siv ntawm cov tso zis fiber ntau tau siv network nrog 250 Mbps bandwidth.
Fiber Optical splitter ua hauj lwm txoj cai.
Raws li qhov optical splitter nrog 2x64 split configurations, nws yog ntau nyuab tshaj qhov optical splitter nrog 1 x 4 split configurations. Muaj ob lub tswv yim txuas thiab sixty-four output terminals hauv optical splitter nrog 2x64 split configurations. Qhov nws muaj nuj nqi yog muab faib ob kab teeb pom kev ua los ntawm ob tug neeg lub tswv yim fais fab mus rau plaub caug-plaub teeb kab thiab xa lawv mus txog rau caum-plaub lub teeb tawm ib tus neeg tawm.
Dab tsi yuav tsum tau muab sau tseg yog tias lub teeb uas muaj teeb pom kev zoo yuav ua los yog tsis muaj qhov muag fais fab zoo li qhov teeb meem ntawm qhov teeb meem. Tus designer yuav zoo dua los coj nws mus rau hauv kev xav thaum tsim cov laj kab paj nruag optical tes hauj lwm.
Optical Splitter Hom Classified by Package Style
Qhov kho qhov muag pom tau zoo nrog cov ntaub ntawv sib txawv, thiab thawj lub pob yuav tsum yog hom lossis hom tawv hlau tsis huv. Fiber optic splitter kem feem ntau yog siv nrog 2 hli los yog 3 hli txheej kab uas hla kab mob, hos lwm yam nquag siv nrog 0.9 hli sab paim hluav taws xob. Tsis tas li ntawd, nws muaj ntau yam txawv split configurations, xws li 1x2, 1x8, 2x32, thiab lwm yam. Nrog rau kev tsim kho qhov muag optical splitter manufacturing technology, lub fiber optic lag luam yuav pab txhawb siab-kev splitter siv nyob rau hauv lub network qhov chaw nruab nrab yog 2x64 los yog loj dua tam sim no.
Optical Splitter Hom Classified by Medium Medium
Raws li qhov sib txawv kis kab mob, muaj ib hom optical splitter thiab multimode optical splitter. Rau cov multimode ones, cov lus qhia implies tias cov fiber yog optimized rau 850nm thiab 1310nm lag luam. Rau hom ib yam nkaus xwb, cov kab lus txhais tau hais tias lub fiber yog optimized rau 1310nm thiab 1550nm lag luam. Lub caij no, raws li kev ua hauj lwm wavelength qhov txawv, muaj ib qhov rai thiab qhov rais nruab nrab qhov muag qhov sib tw. Lub qhov rais nkaus fais fab fiber optic splitter yog siv ib lub lag luam wavelength, thaum lub qhov rais ob sab fiber ntau optic splitter nrog ob txoj haujlwm wavelengths.
Optical Splitters Hom Hom Ntawv los ntawm Cov Txheej Txheem Tsim
Rau lub hauv paus ntawm txawv manufacturing cov txheej txheem, muaj ob hom fiber optic splitter hom, uas yog siv nrov hnub no. Ib qho yog cov khoom siv fais fab fused, fused biconic tapered (FBT) splitter, uas nta cov nqi sib tw; thiab ib qho yog planar lightwave circuit (PLC) splitter, uas muaj qhov sib npaug loj thiab kev sib foob rau kev siv ntau daim ntawv. Ob ntawm lawv muaj qhov zoo thiab yuav siv tau rau hauv cov ntawv thov sib txawv.
Fused Biconic Tapered (FBT) Optical Splitters
FBT splitter (Pom daim duab 2) yog tsim los ntawm cov cuab yeej txwm siv nrog ntau tshaj 20 xyoo keeb kwm. Nws cov txheej txheem raug tsim yog raug thiab tus raug tsim yog qis dua PLC splitter, yog li ntawd FBT optical splitter yuav tsum tau muab tso rau hauv tus nqi zoo hauv hnub no lub fiber optic lag luam.
FBT splitters
Hauv kev tsim cov txheej txheem ntawm FBT splitter, muaj ob los yog ntau cov fibers muab tso ua ke, feem ntau sib ntswg ncig ib leeg thiab fused ua ke los ntawm kev thov cua sov thaum lub koom txoos tab tom nyob rau hauv elongated thiab tapered. Cov fused fused muaj kev tiv thaiv los ntawm ib lub iav substrate thiab ces tiv thaiv los ntawm ib txoj hlua khov tsis xeb. Lub caij no, muaj lub teeb liab los ntawm kev sib txuas ntawm qhov kev sib txuas ntawm qhov sib tw kom tau raws li cov kev cai hauv cov ntawv.
Nta, FBT splitters yog dav siv nyob rau hauv cov kev siv kho qhov muag tsis pom zoo, tshwj xeeb tshaj yog nyob rau hauv lub network qhov chaw cais qhov tsis loj tshaj 1 x 4. Qhov tseeb, muaj qhov me me drawback ntawm FBT splitter, split configuration. Hauv cov ntsiab lus, yog xav paub ntau tshaj plaub zaug, yuav tsum tau sib cais ntau FBT cais tawm ntawm qhov sib txuam ua ke kom muab ntau npaum li cas, xws li cov ntoo splitter. Los ntawm kev siv tus qauv no, lub pob loj nce ntxiv vim ntau FBT splitters thiab txoj kev poob qis kuj nce nrog rau cov kev faib ntau ntxiv. Yog li, yog tias cov khoom phom siab tshaj plaws yuav tsum muaj, me me pob thiab tsawg insertion poob kuj yuav tsum tau, koj tau pom tias yuav xaiv PLC splitter, siv FBT splitter.
Planar Lightwave Circuit Court (PLC) Optical Splitters
Nrog cov technology ntau dua, PLC splitter (Saib Daim Duab 3) muab kev daws zoo dua rau cov kev siv nrog kev faib loj dua. Meej txawv ntawm cov txheej txheem tsim ntawm FBT splitters, hauv cov txheej txheem tsim ntawm PLC optical splitters, cov waveguides yog qhia los ntawm kev siv lithography mus rau silica iav substrate, uas tso cai rau cov kev feem pua ntawm lub teeb. Vim li ntawd, cov PLC splitter muaj ntau seem uas yog qhov sib txawv me ntsis hauv ib lub pob.
PLC splitters
Nrog txoj kev loj hlob sai ntawm FTTx thoob ntiaj teb, qhov yuav tsum tau ua kom loj dua qhov sib txeeb (1x32, 2x64, thiab lwm yam) hauv cov tes hauj lwm no kuj tau hlob tuaj ua hauj lwm pab pawg neeg. Vim nws qhov kev pab cuam muaj txiaj ntsig ntawm kev faib loj dua, cov PLC splitter siv ntau dua nyob rau hauv lub network qhov chaw cais kev loj tshaj 1 x 4.
FBT vs PLC Optical Splitter
FBT splitter yog tsim tawm ntawm cov ntaub ntawv uas yooj yim muaj, xws li steel, fiber, kub dorm thiab lwm tus. Tag nrho cov khoom no yog pheej yig kom qhov hom fiber ntau optical splitter yog tsawg. Cov cuab yeej ntawm cov cuab yeej tsim yog yooj yim, uas muaj feem ntawm nws cov nqi thiab. PLC splitter manufacturing tshuab ntau dua. Nws siv kev siv tshuab nruab nrab ntawm semiconductor (lithography, etching, developer technology), li no nws yog qhov nyuaj dua los ua kev tsim. Yog li ntawd, tus nqi ntawm lub cuab yeej yog siab dua. Txawm hais tias tus nqi ntawm PLC splitter yog siab tshaj FBT splitter, PLC splitter yog ntau txhim khu kev qha thaum piv rau FBT splitter. Lwm yam kev sib txawv ntawm FBT thiab PLC splitters yog qhia raws li nram qab no:
| FBT Splitter | PLC Splitter | |
|---|---|---|
| Kev khiav haujlwm Wavelength | 1310 nm, 1550 nm, 850 nm | Tag Nrho Wavelength (1260-1650 Nm) |
| Inputs / Outputs | Ib lossis ob txoj kev siv nrog ntau tshaj 32 daim txiag. | Ib lossis ob txoj kev siv nrog ntau tshaj 64 daim txiag. |
| Faib Ratio | Customizable. Tshwj xeeb hom xws li 1: 3, 1: 7, 1:11 split ratio yog muaj. | Non-customizable. Tsuas standard versions xws li 1: 2, 1: 4 thiab 1: 8 thiab li ntawm. |
| Qhov loj | Nws loj dua hauv qhov loj thiab tsis tuaj yeem yooj yim rau hauv txhua lub txee. | Nws yog me ntsis thiab yooj yim rau hauv lub txee thiab txuag tau ntau qhov chaw |
| Assymetric ntawm kev sib tw ntawm ib ceg kab lis kev cai | Kev kho tshwjxeeb zoo sib xws. | Txoj kev sib tw faib ua ke |
