A high-speed variable fiber-optic attenuator is introduced by using a digitally controlled multi-pixel liquid crystal device. A proof of concept attenuator is experimentally demonstrated using a 33-pixel ferroelectric liquid crystal device. The attenuator gives a 26 dB dynamic range, a 0.18 dB polarization dependent loss, a 1.26 dB structure loss, and a 100 microsecond(s) switching speed, all at 1319 nm. The attenuator features digital control, broadband operation, no moving parts, fault-tolerance, low loss, and low electric power consumption.
