[摘要] 10 G 无源光纤网络(PON)标准已成熟多年,并逐步进入规模商用。随着增强现实(AR)/虚拟现实(VR)等技术应用及5G时代的到来,使得建设固移融合(FMC)的光接入网成为趋势,并且对PON技术未来带宽和时延等提出了更高的要求。下一代(NG)-PON有单波长提速和多波长叠加2个技术路径。认为NG-PON已成为研究热点,运营商、设备商及标准组织都在该领域积极投入。NG-PON将有着广阔的应用前景。

[Abstract] 10 G passive optical network (PON) standard has matured and commercialized. With the application of augmented reality (AR), virtual reality (VR), and the arrival of 5G era, the constructing of the optical access network of fixed and mobile convergence (FMC) has become a trend, and higher requirements for the future bandwidth and delay of PON technology are needed. Two technical paths are considered in next-generation (NG)-PON: single wavelength speed increase and multi wavelength stacking. NG-PON technology which operators, equipment providers and standard organizations are actively invested in, has become a research hotspot, and will have a broad application prospects.
