Error Resilient Secure Multi-gigabit Optical Link Design for High Energy Physics Experiment

This paper presents a novel design for single channel error resilient secured multi-gigabit optical link for High-Energy Physics (HEP) experiment. The work discusses the logic core implemented on the latest Altera high performance Arria10 FPGA board, having 20nm chip technology. A novel data communication scheme is proposed for this HEP experiment that preserves the DC-balance of the line and allows forward error correction (FEC) with encryption. It is implemented through concatenated blocks of Scrambler, Golay triple error correction coder, AES (Advanced Encryption Standard) cipher and Helical Interleaver. The link operates at a frequency of 8.192 Gbps. Novelty of our design is justified through the performance measurement of the minipod-optical transmitters/receivers.
