Abstract: Embodiments of the present application provide a method for controlling voltages of a liquid crystal on silicon (LCoS) two-dimensional array which includes a plurality of pixel sets, and the plurality of pixel sets include a first pixel set and a second pixel set. The method includes: determining a plurality of bit sequences, where the plurality of bit sequences include a first bit sequence and a second bit sequence; controlling a voltage of the first pixel set by using the first bit sequence; and controlling a voltage of the second pixel set by using the second bit sequence, where the first pixel set and the second pixel set are in different phase cycles in a port direction of the LCoS two-dimensional array, the first pixel set and the second pixel set have a same phase, and duty ratios of the first bit sequence and the second bit sequence are the same.

Abstract: This application discloses a service data processing method and device. A transmit-end device may generate an optical transport network (OTN) encapsulated signal carrying service data, and generate at least n FlexO (flexible optical transport network) frames based on the OTN encapsulated signal and send the at least n FlexO frames, where r FlexO frames in the at least n FlexO frames carry service check data, and the service check data may be used to restore the service data when bit error rates of k FlexO frames are greater than a reference bit error rate. In this way, if no more than r physical ports included in a FlexO group interface fail, or a bit error rate of no more than r FlexO frames is greater than the reference bit error rate due to another reason, a receive-end device may restore the service data through a received FlexO frame.
