FCfiber optic attenuatorndi chipangizo chosagwira ntchito chomwe chimagwiritsidwa ntchito kuchepetsa matalikidwe a chizindikiro chowala popanda kusintha kwambiri mawonekedwe a mafundewo.Izi nthawi zambiri zimakhala zofunikira mu Dense Wave Division Multiplexing (DWDM) ndi Erbium Doped Fiber Amplifier (EDFA) ntchito zomwe wolandira sangathe kuvomereza chizindikiro chopangidwa kuchokera ku magetsi apamwamba kwambiri.
FC attenuatorimakhala ndi mtundu wamtundu wachitsulo-ion doped fiber yomwe imachepetsa chizindikiro cha kuwala pamene ikudutsa.Njira yochepetserayi imalola kugwira ntchito kwapamwamba kuposa kuphatikizika kwa ulusi kapena ma fiber offsets kapena kuchotsera ulusi, zomwe zimagwira ntchito molakwika m'malo motengera chizindikiro cha kuwala.FC attenuators amatha kuchita mu 1310 nm ndi 1550 nm pa single-Mode ndi 850nm ya Multi-Mode.
FC attenuatorsamatha kupirira pa 1W ya kuwala kwamphamvu kwamphamvu kwa nthawi yayitali, kuwapangitsa kukhala oyenera EDFA ndi mapulogalamu ena apamwamba kwambiri.Low Polarization Dependent Loss (PDL) ndi kugawa kokhazikika komanso kodziyimira pawokha kumawapangitsa kukhala abwino kwa DWDM.
