摘要
据我们所知，本文提出了一种基于平面光频率梳（OFC）的波分复用无源光网络（WDM-PON）新方案。使用 OFC 作为系统的光源可以实现光网络单元（ONU）的无色化，下行数据的直接检测进一步简化了 ONU 结构。由于梳状线的相干性，上行数据的相干解调提高了系统性能。本研究对拟议系统的性能和功率预算进行了研究。研究结果表明了所提方案的灵活性、有效性和实用性，可应用于未来的大容量光接入网络。
Scheme for a WDM-PON with colorless optical network units based on a flat optical frequency comb.
A new, to the best of our knowledge, scheme for a wavelength division multiplexing passive optical network (WDM-PON) based on a flat optical frequency comb (OFC) is proposed. Using an OFC as the optical source of the system can realize the colorlessness of optical network units (ONUs), and the direct detection of the downlink data further simplifies the ONU structure. The coherent demodulation of the uplink data improves the system performance due to the coherence of the comb lines. In this research, the proposed system is studied for its performance and power budgeting. The results show the flexibility, effectiveness, and practicability of the proposed scheme, which can be applied to future high-capacity optical access networks.
