    Abstract: Embodiments of the present disclosure provide an information processing apparatus, a network node, and an information processing method. The information processing apparatus may include an inverse fast Fourier transform (IFFT) module, a precoding module, and a determining module. The IFFT module is configured to separately perform IFFT processing on N frequency-domain data streams to acquire N time-domain data streams, where N is a positive integer. The precoding module is configured to perform precoding processing on the N time-domain data streams to acquire a precoding processing result. The determining module is configured to determine, according to the precoding processing result, an orthogonal frequency division multiplexing OFDM symbol to be sent over each antenna of M antennas.

    Abstract: The present invention discloses: when a first laser in N lasers is switched to a second idle laser in M lasers, a wavelength of a wavelength-selective optical element to which the first laser is coupled is adjusted from a first wavelength to a second wavelength, and the second wavelength is different from the N wavelengths. Similarly, when a first optical receiver in N optical receivers is switched to a second idle optical receiver in M optical receivers, a wavelength of a wavelength-selective optical element to which the first optical receiver is coupled is adjusted from a first wavelength to a second wavelength, and the second wavelength is different from the N wavelengths.
