Cov yam ntxwv tseem ceeb thiab kev nce qib tsis ntev los no ntawmKev kub ceev Photodetector
Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, daim ntawv thov kev kub ceev Photodetector (optical nrhiav module) nyob rau hauv ntau lub teb yog ntau thiab ntau dua.Daim ntawv no yuav qhia txog 10G high-speedPhotodetector(optical detection module) uas integrates ib tug high-speed teb avalanche photodiode (APD) thiab lub suab nrov nrov amplifier, muaj ib hom / multi-mode fiber txuas input, SMA connector tso zis, thiab muaj siab nce, siab rhiab heev, AC ua ke tso zis , thiab flat nce.
Lub module siv lub InGaAs APD ntes nrog spectral ntau ntawm 1100 ~ 1650nm, uas yog tsim rau high-speed optical fiber kis systems thiab high-speed optical pulse detection.Hauv kev sib txuas lus kho qhov muag, qhov rhiab heev thiab ceev ntawm photodetectors yog qhov tseem ceeb ntawm kev ua tau zoo.Lub siab rhiab heev ntawm lub module ncav cuag -25dBm thiab lub saturation optical zog yog 0dBm, kom ntseeg tau tias cov ntaub ntawv txhim khu kev qha kis tau tus mob nyob rau hauv tsawg optical zog tej yam kev mob.
Tsis tas li ntawd, lub module kuj tseem ua ke nrog lub preamplifier thiab booster circuit, uas tuaj yeem txo cov suab nrov thiab txhim kho lub teeb liab rau suab nrov piv.AC txuas cov zis tuaj yeem txo qhov cuam tshuam ntawm DC tivthaiv thiab txhim kho cov teeb liab zoo.Qhov nce flatness tus yam ntxwv ua rau lub module kom muaj kev ruaj ntseg nce ntawm ntau lub wavelengths, ntxiv optimizing lub teeb liab zoo.
Nyob rau hauv daim ntawv thov, lub module yog tsuas yog siv nyob rau hauv high-ceev mem tes nrhiav kom tau, high-speed chaw kho qhov muag kev sib txuas lus thiab high-speed optical fiber kev sib txuas lus.Nrog rau txoj kev loj hlob ntawm thev naus laus zis, qhov kev thov hauv cov teb no kuj nce ntxiv.Yog li ntawd, kev txhim kho thiab kev siv ntawm no module yog qhov tseem ceeb heev.
Lub module kev ua tau zoo thiab daim ntawv thov ua rau nws yog ib qho ntawm feem ntauadvanced photodetectorsntawm kev ua lag luam hnub no.Nws muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev ruaj ntseg siab thiab kev ntseeg siab, thiab tuaj yeem ua tau raws li cov kev xav tau ntawm ntau qhov chaw.Nyob rau hauv lub neej yav tom ntej txoj kev loj hlob, nrog kev vam meej tsis tu ncua ntawm technology thiab kev nthuav dav ntawm daim ntawv thov kev lag luam, cov module yuav siv tau ntau dua thiab txhawb nqa.
