OREANDA-NEWS. Mitsubishi Electric Corporation announced today it has developed an error-correction technology that achieves a coding gain of 12.0dB, the world’s highest level as according to internal research, for high-speed and high-capacity optical communication systems over long distances. The technology will be launched in the fiscal year starting in April 2014.

Error-correction technology allows a sender to encode a message with redundancy by using error-correction codes. Coding gain is the difference in the signal-to-noise ratio (SNR) levels between uncoded and coded systems required to reach the same bit error rate (BER) levels when used with the error-correction code.

Mitsubishi Electric’s new error-correction technology enables transmissions four times longer than conventional codes, such as Reed-Solomon codes standardized by ITU-T G.709. As a result, the technology enables long-haul transoceanic transmissions, such as those between Japan and the United States (about 9,000km), at 100Gbps per wavelength for high-capacity communication systems.
