Cyclic prefix free 10-Gb/s OFDM for a DML-based long-reach optical access using joint time and frequency domain equalization algorithm

Without using a cyclic prefix, a DML-based 10-Gb/s OFDM at 2.5-GHz bandwidth transmission over 65-km SMF is demonstrated to be possible while maintaining the efficient throughput and short-latency time required for future long-reach access systems.
