Abstract
An optical transponder includes a mapping unit mapping, out of multiple types of signals including a first client signal and a second client signal that transmission rates are different from each other, the first client signal having a lower transmission rate to a Generic Framing Procedure (GFP) frame defined in ITU-T Recommendations; a coding unit applying 64B/66B coding to the first client signal mapped to the GFP frame; and a multiplexing unit multiplexing the first client signal to which the 64B/66B coding has been applied and the second client signal in a frame conforming to an Optical Transport Network (OTN) defined in ITU-T Recommendations; in which the first client signal and the second client signal are accommodated in an identical frame in a mixed manner and transmitted as an optical signal having one wavelength.
