FPGA verification of a single QC-LDPC code for 100 Gb/s optical systems without error floor down to BER of 10−15

We present FPGA-based emulation results of a single QC-LDPC code with 20% redundancy designed for applications in 100 Gb/s optical transmission systems. Error floor-free transmission can be achieved at BER of 10
⁻¹⁵
with a Q factor of 5.9 dB.
