We experimentally demonstrate a single-wavelength 100 Gbps downstream PON transmission aided by chromatic dispersion digital pre-compensation (CD-DPC) using simple digital signal processing (DSP) finite impulse response (FIR) filters in combination with an IQ Mach–Zehnder modulator (IQ-MZM) at the transmitter side and direct-detection receiver at the optical network unit (ONU). A reach of 50 km over standard single-mode fiber in C-band and an optical distribution network (ODN) loss of 28.5 dB are achieved. Transmission of 50 and 125 Gbps over 50 km of fiber is also tested, achieving 32 dB and 24 dB of ODN loss, respectively. The complexity of the filters, the optimization of the main design parameters, and the tolerance of the CD-DPC to the uncertainty of the exact accumulated link dispersion are analyzed in detail.

100+ Gbps/50km C 波段下行 PON 使用 CD 数字预补偿和直接检测 ONU 接收器

我们使用简单的数字信号处理 (DSP) 有限脉冲响应 (FIR) 滤波器结合 IQ Mach-Zehnder 调制器,通过实验证明了单波长 100 Gbps 下游 PON 传输,该传输由色散数字预补偿 (CD-DPC) 辅助。 IQ-MZM)在发射器侧,直接检测接收器在光网络单元(ONU)。通过 C 波段的标准单模光纤实现了 50 公里的传输距离和 28.5 dB 的光分配网络 (ODN) 损耗。还测试了 50 和 125 Gbps 在 50 公里光纤上的传输,分别实现了 32 dB 和 24 dB 的 ODN 损耗。详细分析了滤波器的复杂性、主要设计参数的优化以及 CD-DPC 对精确累积链路色散不确定性的容忍度。
