직접 변조 직접 검출 광전송 시스템에서 쌍별 분포된 확률론적 성상 성형 변조를 이용한 36 GBaud PAM-8 신호의 전송 실험36-Gbaud PAM-8 signal transmission in IM/DD system using pairwise-distributed amplitude shaping
We experimentally demonstrate the 36-Gbaud probabilistically-shaped PAM-8 signal transmission over 10-km single-mode fiber. The receiver sensitivity after FEC decoding and inverse distribution matcher is improved by more than 1 dB compared to uniform-distributed signals.
