Error-correction multiplexing apparatus, error-correction demultiplexing apparatus, optical transmission system using them, and error-correction multiplexing transmission method |
摘要 |
A first demultiplexer and a second demultiplexer receive and demultiplex STM-64 data to generate parallel data. A FEC frame generating encoder carries out error correction encoding operation in a column direction of the parallel data that constitutes a matrix, adds a resulting error correcting code to the parallel data, carries out error correction encoding operation in a row direction of the parallel data, and further adds a resulting error-correcting code to the parallel data. A first multiplexer and a second multiplexer multiplex the error-correction-encoded parallel data, and output the data as a FEC frame.
