Abstract :
Real-time optical OFDM transceivers with 128-QAM encoding are experimentally demonstrated, for the first time, which enable 5.25 Gb/s end-to-end transmission with the highest spectral efficiency of 5.25 bit/s/Hz over 25 km (500 m) SMF(MMF) IMDD systems involving directly modulated lasers.
