Abstract: An optical communication system includes a sending device, an optical cross-connect (OXC) device, and a first receiving device. The sending device is configured to send a modulated first service optical signal to the OXC device. The OXC device is configured to receive the modulated first service optical signal through a first input port, and divide the modulated first service optical signal into N1 first optical signals based on a wavelength. The OXC device is configured to send M1 first optical signals to the first receiving device through M1 first output ports.

Abstract: Methods, apparatuses, and systems are provided. A method includes obtaining a wavelength division multiplexing optical signal. The wavelength division multiplexing optical signal includes N pairs of optical signals. Each pair of optical signals includes a first optical signal and a second optical signal that are of different wavelengths and whose polarizations are orthogonal to each other. N is an integer greater than 1, and a frequency of at least one of N first optical signals and a frequency of at least one of N second optical signals are within a zero-dispersion frequency ZDF region of an optical fiber. The method further includes sending the wavelength division multiplexing optical signal through the optical fiber.

Abstract: Example systems and nodes are provided. An example system includes a first node, a second node, and an optical fiber that connects the first node and the second node. A zero-dispersion wavelength (ZDW) of the optical fiber belongs to a ZDW region. The optical fiber is configured for transmission of N first-direction wavelength channels and N second-direction wavelength channels. N is an integer greater than 2. At least two first-direction wavelength channels and at least one second-direction wavelength channel, or at least two second-direction wavelength channels and at least one first-direction wavelength channel, are located in the ZDW region. The first-direction wavelength channel and the second-direction wavelength channel that are in the ZDW region are mixedly distributed. The first-direction wavelength channel is sent by the first node to the second node, and the second-direction wavelength channel is sent by the second node to the first node.
