Abstract :
A simple, highly-effective, DSP-free, optical OFDM(OOFDM) synchronous clock recovery technique preserving system performance and enhancing stability is proposed and experimentally demonstrated, for the first time, in real-time end-to-end, 11.25Gb/s 64-QAM OOFDM, directly-modulated-DFB-based, 25km IMDD systems.
