Cov yam ntxwv tseem ceeb thiab kev nce qib tsis ntev los no ntawmKev kub ceev Photodetector
Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov ntawm kev kub ceev Photodetector (module nrhiav pom kev zoo) nyob rau hauv ntau qhov chaw muaj ntau dua thiab dav dua. Daim ntawv no yuav qhia txog 10G ceev ceevLub tshuab ntes duab(optical detection module) uas koom ua ke nrog high-speed response avalanche photodiode (APD) thiab lub amplifier suab qis, muaj ib hom / ntau hom fiber txuas nrog input, SMA connector output, thiab muaj high gain, high sensitivity, AC coupled output, thiab flat gain.
Lub module siv lub InGaAs APD detector nrog ntau yam spectral ntawm 1100 ~ 1650nm, uas yog tsim rau cov kab ke xa xov fiber ntau ceev thiab kev ntes lub zog ceev ntawm lub teeb. Hauv kev sib txuas lus optical, qhov rhiab heev thiab qhov ceev ntawm cov photodetectors yog cov cim qhia kev ua tau zoo tseem ceeb. Qhov rhiab heev ntawm lub module ncav cuag -25dBm thiab lub zog optical saturation yog 0dBm, ua kom ntseeg tau tias kev xa cov ntaub ntawv txhim khu kev qha nyob rau hauv cov xwm txheej fais fab optical qis.
Ntxiv mus, lub module kuj tseem muaj lub preamplifier thiab booster circuit, uas tuaj yeem txo qhov suab nrov thiab txhim kho qhov sib piv ntawm lub teeb liab thiab suab nrov. Lub AC coupled output tuaj yeem txo qhov cuam tshuam ntawm DC Cheebtsam thiab txhim kho qhov zoo ntawm lub teeb liab. Qhov nce flatness yam ntxwv ua rau lub module muaj qhov nce ruaj khov ntawm ntau lub wavelengths, ntxiv qhov zoo ntawm lub teeb liab.
Hauv daim teb ntawm daim ntawv thov, lub module feem ntau yog siv rau kev tshawb nrhiav lub zog ceev ceev, kev sib txuas lus optical ceev ceev thiab kev sib txuas lus fiber ntau ceev ceev. Nrog rau kev txhim kho thev naus laus zis, qhov kev thov hauv cov teb no kuj nce ntxiv. Yog li ntawd, kev txhim kho thiab kev siv lub module no yog qhov tseem ceeb heev.
Qhov kev ua tau zoo thiab daim ntawv thov ntawm lub module ua rau nws yog ib qho ntawm cov khoom siv tshaj plawscov khoom siv photodetectors siab heevnyob rau hauv kev ua lag luam niaj hnub no. Nws muaj cov yam ntxwv ntawm kev ua tau zoo, kev ruaj khov siab thiab kev ntseeg siab siab, thiab tuaj yeem ua tau raws li cov kev xav tau ntawm ntau qhov chaw sib txawv. Hauv kev txhim kho yav tom ntej, nrog rau kev nce qib ntawm thev naus laus zis thiab kev nthuav dav ntawm cov chaw thov, lub module yuav raug siv thiab txhawb nqa ntau dua.
