Abstract
An optical communication apparatus has an interface circuit that acquires transfer condition information including a bit rate and a channel spacing of an optical network, a processor that selects a modulation scheme in accordance with the transfer condition information and operates in the modulation scheme, wherein the processor is configured to select a first modulation scheme when the bit rate is greater than a first value in accordance with the channel spacing, and select a second modulation scheme when the bit rate is smaller than the first value, the second modulation scheme having a data transfer performance higher than the first modulation scheme.
