    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: 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: Embodiments of the present invention provide a method and an apparatus for sending a non-data frame. The method for sending a non-data frame includes: determining an access category for which a transmission opportunity of a shared medium has been obtained, where the obtained transmission opportunity of the shared medium is obtained for the access category through contention according to an enhanced distributed channel access mechanism; and sending a non-data frame according to the access category for which the transmission opportunity of the shared medium has been obtained. In this way, different quality-of-service requirements of a non-data frame and a data frame are met while fairness is considered, thereby avoiding that a management and control message is not sent in time because a non-data frame and a data frame are transmitted according to a same access category.

    Abstract: A wavelength calibration method for a microring filter includes selecting N wavelengths from M wavelengths, and performing operations on the microring filter for each of the N wavelengths, thereby obtaining N sets of calibrated voltages, and obtaining, based on N sets of calibrated voltages, M−N sets of calibrated voltages corresponding to M−N wavelengths of the M wavelengths. The operating include adjusting thermal tuning power of the plurality of microrings in response to one set of voltages, and obtaining a plurality of sets of voltages that enable monitored optical power to have an extreme value, and using the plurality of sets of voltages as a reference, adjusting the thermal tuning power of the plurality of microrings in response to another set of voltages, and determining one of the N sets of calibrated voltages from the plurality of sets of voltages.

    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.
