Abstract: A schedule processing method includes displaying a 24-hour interval timescale in a first display area in a user interface. The method further includes displaying, in the first display area, an identifier corresponding to each schedule on a day, where a display location of the identifier corresponding to each schedule is associated with time information of each schedule. The user interface includes the first display area and a second display area. The method further includes in response to a detected first view operation performed by a user on a first identifier, displaying, in the user interface, information about a schedule corresponding to the first identifier.

Abstract: A wavelength calibration method, apparatus, and system is disclosed. The method includes: selecting sonic wavelengths from a plurality of wavelengths, and performing the following operations on a microring filter for each of the some wavelengths, to obtain sets of calibrated voltages of the some wavelengths: (1) adjusting thermal tuning power of multiple microrings by using one set of voltages, and obtaining multiple sets of voltages that enable monitored optical power to have an extreme value, and (2) using the multiple of sets of voltages as a reference, adjusting the thermal tuning power of the multiple microrings by using another set of voltages, and determining one of the sets of calibrated voltages, which enables the monitored optical power to converge, from the multiple sets of voltages; and then, obtaining, through calculation based on the sets of calibrated voltages of the some wavelengths, sets of calibrated voltages of other wavelengths.

Abstract: An ADD/DROP filter and an optical add/drop multiplexer are disclosed. An ADD/DROP filter includes an input port, an output port, an add port connecting to a modulator, and a drop port. The modulator is configured to load a pilot signal to a first optical signal to obtain a second optical signal, and transmit the second optical signal to the add port. A third optical signal is input to the input port. A wavelength difference between the second optical signal and the third optical signal is an integral multiple of a free spectral range. A power detector is connected to the output port and/or the drop port. The power detector is configured to obtain an output optical signal from the output port or the drop port and detect an optical power of the output optical signal.

Abstract: Embodiments of this application provide a modulation method and apparatus. The method includes: receiving a code word sequence, where each code word includes N bits, and the code word sequence includes at least a first code word; mapping the code word sequence into M sequences, where each sequence includes N/M bits from the first code word; mapping the M sequences into a symbol sequence, where each symbol is corresponding to M bits, the M bits are respectively from the M sequences, first bits corresponding to N/M first-type symbols are from the first code word, and second bits corresponding to N/M second-type symbols are from the first code word. Thus a signal-to-noise ratio requirement during higher order modulation lowered.
