Original Abstract Submitted
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.
