摘要： An apparatus for implementing low power consumption for data switching device includes a dormancy management module that controls an upper layer logic component in a device to enter a low power consumption state when a current state parameter of the device satisfies a preset dormancy configurationcondition; detects whether an energy consumption state of a transmission medium is active; and wakes up the upper layer logic component in the device to enter a normal working state if the energy consumption state of the transmission medium is active. When a preset condition is satisfied, upper layer logic components such as a CPU, a network processor and an optical module in the device, properly stop full-time operation to save energy.

摘要： This application provides a mode division multiplexer, which includes a metasurface of an electromagnetic resonance unit that has a plurality of sub-wavelengths disposed in an array. The electromagnetic resonance unit is configured to perform phase modulation on a beam transmitted to the electromagnetic resonance unit, to convert a spatial mode order of the beam. Because a size of the electromagnetic resonance unit is a sub-wavelength, and a pixel size of the electromagnetic resonance unit is smaller than a pixel size of a spatial light modulator in the prior art, crosstalk between different spatial modes after phase modulation performed by the mode division multiplexer is comparatively low. In this way, the crosstalk is comparatively small when beams in different spatial modes are multiplexed into a few-mode/multi-mode fiber. The mode division multiplexer in this application can implement polarization-independent phase modulation.
