Fiber Attenuator
Raws li cov khoom siv khoos phis tawm dhau mus, qhov cuab yeej siv hluav taws xob tau siv rau qhov debugging kho qhov muag lub zog ua tau zoo hauv kev sib txuas lus kho qhov muag, kev ntsuas hluav taws xob kom debug ntawm cov cuab yeej siv debug fiber, thiab attenuation ntawm cov teeb liab fiber ntau. Cov khoom lag luam yog siv cov attenuating fiber ntau doped nrog ions hlau los kho lub zog kho qhov muag mus rau qib uas xav tau.
txoj haujlwm ua haujlwm:
1, Huab Cua Kev Rho Tawm Tshuab
Kev sib kis ntawm lub teeb hauv lub fiber yog qhov txwv tsis pub ua raws li txoj cai ntawm kev cuam tshuam tag nrho thiab tsis tuaj yeem tawg, ua kom txoj kev cia siab ruaj khov. Thaum nws muab tawm los ntawm cov paib, ib qho huab cua sib txawv ntxiv rau nruab nrab ntawm cov pa roj carbon thiab fiber, thiab lub teeb tawg tau tawg, ua rau lub ntsej muag ua kom pom qhov ci. Txij thaum lub teeb tawg tau tawg los ntawm qhov teeb meem mus rau saum huab cua los ntawm cov xov paj zoo tib yam, txhawm rau tswj hwm tus nqi attenuation rau qee yam, nws yog qhov tsim nyog los xyuas kom meej cov kev sib cais deb thiab tswj kev sib cais ntawm cov fibers ntawm ob hnub. Lub flanged tsau attenuator thiab lub ntsej muag kho kom haum tuaj yeem tsim los ntawm txoj ntsiab cai no. Lub flange hom tsau attenuator siv ib qho sib cais attenuating daim los ua kom muaj qee qhov tuab ntawm cov attenuating daim ntawv raws li lub teeb, thiab daim attenuating yog cog nyob rau hauv lub flange los kho qhov teeb meem attenuation. Cov flanged tunable optical attenuator siv lub hauv paus ntsiab lus ntawm kev sib hloov tshuab los kho qhov kev ncua deb ntawm cov txuas ntawm ob qho kawg los ntawm kev sib hloov tshuab, uas tuaj yeem attenuate lub teeb ntawm 0 thiab 30 dB.
2, Txawv Tebchaws Misalignment Technology, txoj kev no yog hloov me ntsis ntawm cov tub ntxhais ob txoj kab hluav taws xob kom ua tiav cov hwj huam poob.
Los ntawm kev siv cov pigtail zoo tib yam, qhov tseem ceeb ntawm ob lub pigtails yog welded nyob rau hauv cov ntaub ntawv ntawm misalignment nrog lub fusion splicer, yog li qhov eccentricity poob tshwm sim thaum lub sijhawm sib kis ntawm lub teeb, thiab ib lub txuas txuas tsau attenuator, tseem hu ua online tsau. attenuator, yog tau. Cov.
3. Attenuating Fiber Tshuab, raws li kev nqus ntawm lub teeb los ntawm hlau ions, attenuation fiber ntawm doped hlau ion tau tsim, uas muaj tib lub attenuation coefficient nyob rau hauv ib mais li cov fiber zoo tib yam. Lub attenuation fiber kuj tseem muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txuam, tab sis qhov attenuation no Cov coefficients tsis suav nyob rau hauv mais tab sis hauv millimetres. Hla lub attenuating fiber ntau rau hauv cov ceramic ferrule? Tom qab kev ua haujlwm tshwj xeeb, nws tuaj yeem ua rau hauv qhov ruaj khov thiab ruaj khov tsis zoo.
4, Txoj Kev Txhim Kho Cov Qauv iav
Optically polished nruab nrab nqus iav iav kuj tseem tuaj yeem siv hauv kev tsim ua tiav ntawm qhov pom ntawm cov neeg kho qhov muag. Siv cov khoom nqus ntawm lub teeb los ntawm cov khoom siv, nws tau ua rau hauv daim ntawv los yog cov hlua ntawm cov iav dub nruab nrab, uas tau muab tso rau ntawm txoj kev kho qhov muag kom thiaj li sib zog. Cov iav uas nqus tau yog qhov txawv ntawm qhov transmittance T thiab tus nqi attenuation qhia hauv qhov decibels. Transmittance T=kev siv lub teeb ci / xwm txheej teeb pom kev zoo siv, qhov ua kom sib haum η=1 / T, qhov ntsuas kom sib haum tau hais tawm hauv kev txiav txim β=10 x log η=- 10 x logT, tus nqi attenuation qhia hauv decibels tuaj yeem yooj yim kwv yees tus nqi attenuation ntawm lub sij hawm ntawm kev ua ke zaj duab xis yog tau los ntawm kev ntxiv qhov txuas ntawm qhov sib dhos ntawm cov teeb tsa ua kom pom tseeb ntawm cov nqi sib txuas ua ke ntawm cov pab pawg sib txuas nrog ua ke, qhia hauv decibels. Daim ntawv puab tau ua kom muaj tus nqi sib txawv, thiab cov duab txaij ua tau txawv raws tus cwj pwm ntawm cov nqi sib txawv ntawm cov ntu sib txawv ntawm cov xim dub tsis tu ncua nce hauv nws sab hauv. Ib daim ntawm daim ntawv-lub teeb uas muaj lub ntsej muag nqus tau iav tuaj yeem siv los ua lub rooj sib khawm ruaj khov. Kev tshaj tawm ntawm cov ntawv-daim iav ntxig iav tuaj yeem hloov mus ua kev sib cais sib txig sib luag los ntawm roulette hloov dua siab tshiab, thiab cov kab txaij zoo li daim iav tuaj yeem ua rau txuas ntxiv kho kom haum los ntawm kev hloov chaw tas mus li.
5, Khoom Siv Hluav Taws Xob Lub Zog Tuav Txheej Txheem Tshuab
Lub tunable optical attenuators nyob rau hauv daim ntawv ntawm cov cua cais thiab nqus iav yog mechanically tunable rau attenuation. Tseem muaj qhov tsawg tsawg ntawm cov cuab yeej siv kho qhov muag kom pom tseeb, xws li tunable diffraction grating thev naus laus zis, MEMS thev naus laus zis, thiab siv tshuab ua kua siv lead ua kua. , magneto-kho qhov muag thev naus laus zis, planar optical waveguide thev naus laus zis.
