Abstract: An optical module includes a processing component and a plug component. The plug component includes a plurality of filters. The plurality of filters are connected to a plurality of secondary ports. The processing component includes a plurality of primary ports. The optical module is in a first connection status or a second connection status. When the optical module is respectively in the first connection status or the second connection status, a wavelength of a second service optical signal or a wavelength of a second local oscillator optical signal that are sent by the plurality of filters varies. When the optical module is in a same connection status, wavelengths of the second service optical signal and the second local oscillator optical signal that are sent by the plurality of filters are identical.

Abstract: A coherent optical receiving apparatus includes a polarization beam splitting unit, an optical frequency mixing unit, and a combining unit. The polarization beam splitting unit is configured to receive local oscillator light in any polarization state, and perform polarization state split on the received local oscillator light to obtain first polarized light in a linear polarization state. The optical frequency mixing unit is configured to perform frequency mixing on the first polarized light and second polarized light, and output mixed light to the combining unit. The second polarized light is polarized light in a linear polarization state obtained by splitting signal light. The combining unit is configured to combine every two paths of light output by the optical frequency mixing unit into one path for output.
