Abstract: We experimentally demonstrate an orthogonal frequency-division multiplexing (OFDM) system with direct detection. Adopting Kramers–Kronig (KK) detection and probabilistic shaping (PS) technology, 140-Gb/s 256-QAM signal can be successfully transmitted over 25-km standard single-mode fiber (SSMF), which… read more here.
