Abstract

Employing 75-piece FPGA implementation, we investigate the performance down to 10(-15) BER of hard-decision 25G-PON LDPC and soft-decision 50G-PON LDPC at a record 90-Gbps throughput. FPGA emulations reveal soft-decision LDPC code offers more than 1.5dB coding gain with no error floor. (C) 2020 The Author(s)
