I-Fiber optic attenuator eguquguqukayo eguquguqukayo iyisisetshenziswa esisetshenziswayo esisetshenziselwa ukunciphisa ubukhulu besignali yokukhanya ngaphandle kokushintsha kakhulu ifomu legagasi ngokwalo.Lokhu kuvame ukuba yimfuneko ezinhlelweni zokusebenza zeDense Wave Division Multiplexing (DWDM) kanye ne-Erbium Doped Fiber Amplifier (EDFA) lapho umamukeli engakwazi ukwamukela isignali ekhiqizwe emthonjeni wokukhanya wamandla aphezulu.
