We experimentally demonstrate the downstream transmission of a 100 Gb/s/λ time division multiplexed passive optical network (TDM-PON) based on four-level pulsed amplitude modulation (PAM-4) in the O-band using 10 Gbps transmitters with semiconductor optical amplifier (SOA) and digital signal processing (DSP) at the receiver. Considering the soft-decision FEC (SD-FEC) threshold (1 × 10−2), power budget of 30.3 dB and 29.3 dB have been achieved after 22 km and 50 km fiber transmission, respectively. There is no observable dispersion penalty after 22 km and 50 km transmission. The possibility of 100 Gb/s/λ PON is first investigated using intensity modulation and direct detection (IM/DD) schemes rather than coherent detection schemes.

SOA 前置放大 100 Gb/s/λ PAM-4 TDM-PON 下行传输,使用 10 Gbps O 波段发射机

我们使用 10 Gbps 发射器和半导体光器件,在 O 波段实验证明了基于四级脉冲幅度调制 (PAM-4) 的 100 Gb/s/λ 时分复用无源光网络 (TDM-PON) 的下行传输放大器 (SOA) 和接收器的数字信号处理 (DSP)。考虑到软判决 FEC (SD-FEC) 阈值 (1 × 10−2),分别在 22 km 和 50 km 光纤传输后实现了 30.3 dB 和 29.3 dB 的功率预算。在 22 公里和 50 公里传输后没有可观察到的色散损失。首先使用强度调制和直接检测 (IM/DD) 方案而不是相干检测方案来研究 100 Gb/s/λ PON 的可能性。
