Abstract
A transmission device is implemented in a first node in an optical transmission system in which a frame is transmitted from the first node to a second node via an optical interface. The transmission device includes a decision unit that decides whether a type of a first error correction code used in the first node is the same as a type of a second error correction code used in the second node. When a type of the first error correction code is the same as a type of the second error correction code, the transmission device transmits the frame to which an error correction code used in the first node is added to the second node without terminating the error correction code.
