本文提出了一种具有动态资源分配和可变速率接入的新型波分复用-正交频多址（WDM-OFDMA）联合无源光网络（uni-PON）架构。它可以提供具有不同接入解决方案的基础设施。光本地终端(OLT)可以根据不同业务的服务质量(QoS)要求，动态地为不同业务分配不同的资源和接入速率。实验已证明使用 4 个波长可实现 109.92 Gb/s 的组合信号。采用物理层自适应算法进行资源分配和可变速率访问。实验中还演示了具有不同资源分配和可变访问速率的不同服务。
This paper proposes a novel wavelength division multiplexing-orthogonal frequency multiple access (WDM-OFDMA) union passive optical network (uni-PON) architecture with dynamic resource allocation and variable rate access. It can offer an infrastructure with different access solutions. According to the quality of service (QoS) requirement of different services, the optical local terminal (OLT) can dynamically assign different resources as well as the access rates to different services. An experiment has been demonstrated with 4 wavelengths achieving combined signal at 109.92-Gb/s. A physical-layer adaptive algorithm is employed for the resource allocation and variable rate access. The different services with different resource allocations and variable access rates are also demonstrated in the experiment.
