Abstract: An optical communications method and an optical communications apparatus are provided. The method is executed on a communications node that includes an input optical modulator array and an output optical modulator array. The input optical modulator array includes N input optical modulators. The method includes determining at least two local input areas from the input optical modulator array, so that each input optical modulator in each local input area is used to receive a foreign signal light. The method also includes determining at least two local output areas from the output optical modulator array. Each output optical modulator in each local output area is used to send the foreign signal light, and each input optical modulator in a local input area is capable of transmitting the signal light to each output optical modulator in a corresponding local output area.

Abstract: A reconfigurable optical add/drop multiplexer includes N input ports, N output ports, M add ports and M drop ports. Each of the N input ports and each of the M add ports is respectively connected to one first polarizer. Each of the N output ports and each of the M drop ports is respectively connected to one second polarizer. A first end of the first polarizer is connected to a second end of the first polarizer, forming a loop including the first polarizer. A first end of the second polarizer is connected to a second end of the second polarizer, forming a loop including the second polarizer. An annular waveguide array is between a loop LIi and a loop LOj. A first polarizer included in the loop LIi is connected to an ith input port. A second polarizer included in the loop LOj is connected to a jth output port.
