<p>An optical transmission system includes a first demultiplexing circuit (11) and a second demultiplexing circuit (12) for demultiplexing STM-64data which has been input so as to generate parallel data, a frame generation FEC encoding circuit (13) for performing an error-correction encoding calculation for the row direction of the matrix formed by the parallel data, adding the error-correction code as the calculation result to the parallel data, performing an error-correction encoding calculation in the line direction of the matrix formed by the parallel data, and adding the error-correction code as the calculation result to the parallel data, and a first multiplexing circuit (14) and a second multiplexing circuit (15) for multiplexing the parallel data which has been subjected to the error correction encoding and outputting it as an FEC frame.</p> |
