“…Forward error correction (FEC) is becoming an increasingly important signal processing scheme employed in modern highspeed long-haul optical transmission systems [1][2][3][4][5]. This is due to the fact that FEC can provide an effective increase of the amplifier spacing, transmission distance, transmission bit rate and the systems capacity [1][2][3][4].…”

“…This is due to the fact that FEC can provide an effective increase of the amplifier spacing, transmission distance, transmission bit rate and the systems capacity [1][2][3][4]. With the increasing development of optical transmission systems toward longer distance, more capacity and higher speed direction, the transmission impairment in optical fibers (such as dispersion, polarization-mode dispersion (PMD) and fiber nonlinearities) can seriously limit the further improvements of the transmission speed and distance [1][2][3][4][5]. So the development of a super forward error correction (Super-FEC) code with more powerful error correction performance has become a research hot in optical transmission systems.…”

In storage and communication systems, the product and concatenation codes, which consist of Reed-Solomon (RS) codes and other error-correction codes, can be utilized to effectively correct burst errors by performing erasures-and-errors decoding. However, the RS codes have two drawbacks: 1) the RS decoders may not detect received erroneous codewords, and 2) the RS decoders may generate valid codewords which are not equal to the transmitted codewords. In the implementation of the product and concatenation codes, such decoding drawbacks can cause the RS code to provide incorrect error-detection information or erasure information to other error-correction codes, resulting in unreliable error-correction performance of the systems. In this study, we propose a new product code to overcome these drawbacks by studying the RS product code (RSPC). The new code combines CRC code with RSPC which is called as CRSPC. In addition, the results of experiments show that the new CRSPC can significantly reduce the probabilities of these drawbacks, thereby improving the performance of erasures-anderrors decoding. With minor modifications, the CRSPC algorithm can be applied to Blueray disc systems which have powerful recording functions in multimedia.

“…The optical signal to noise ratio (OSNR) of a high data rate optical signal would degrade significantly over long transmission distances. Forward error correction (FEC) [6][7][8][9][10][11][12][13][14][15][16] coding techniques with low hardware investment cost and high error-correction performance can effectively compensate for this degradation. This is by adding redundant overhead bits appropriately to the information bits before modulation and transmission.…”

We apply an adaptive forward error correction (FEC) allocation strategy to an Elastic Optical Network (EON) operated with shared backup path protection (SBPP). To maximize the protected network capacity that can be carried, an Integer Linear Programing (ILP) model and a spectrum window plane (SWP)-based heuristic algorithm are developed. Simulation results show that the FEC coding overhead required by the adaptive FEC scheme is significantly lower than that needed by a fixed FEC allocation strategy resulting in higher network capacity for the adaptive strategy. The adaptive FEC allocation strategy can also significantly outperform the fixed FEC allocation strategy both in terms of the spare capacity redundancy and the average FEC coding overhead needed per optical channel. The proposed heuristic algorithm is efficient and not only performs closer to the ILP model but also does much better than the shortest-path algorithm.
