FCfiber ntau optic attenuatoryog ib qho khoom siv passive siv los txo qhov amplitude ntawm lub teeb liab tsis muaj qhov hloov pauv ntawm yoj daim ntawv nws tus kheej.Qhov no feem ntau yog qhov yuav tsum tau muaj nyob rau hauv Dense Wave Division Multiplexing (DWDM) thiab Erbium Doped Fiber Amplifier (EDFA) daim ntawv thov uas lub receiver tsis tuaj yeem txais cov teeb liab tsim los ntawm lub teeb pom kev zoo.
FC attenuatorfeature ib hom khoom ntawm hlau-ion doped fiber ntau uas txo cov teeb liab thaum nws hla.Hom kev attenuation no tso cai rau kev ua haujlwm siab dua li fiber ntau splices lossis fiber ntau offsets lossis fiber ntau clearance, uas ua haujlwm los ntawm misdirecting es tsis nqus cov teeb liab.FC attenuators muaj peev xwm ua tau zoo hauv 1310 nm thiab 1550 nm rau Ib Hom thiab 850nm rau Ntau Hom.
FC cov attenuatorsmuaj peev xwm tiv taus ntau dua 1W ntawm lub teeb hluav taws xob siab rau lub sijhawm ntev, ua rau lawv zoo rau EDFA thiab lwm yam kev siv hluav taws xob siab.Tsawg Polarization Dependent Loss (PDL) thiab qhov ruaj khov thiab ywj pheej wavelength faib ua rau lawv zoo tagnrho rau DWDM.
