接入城域融合网络（AMCN）已被提出作为未来的光通信网络，以实现灵活、动态的带宽分配。 AMCN 需要为光网络单元 (ONU) 使用不同波长的收发器。这导致生产成本增加。尽管全光波长转换器 (AOWC) 缓解了这个问题，但 AOWC 增加了安装成本，因为它由许多昂贵的光学器件组成。我们建议将远程泵送 AOWC (RP-AOWC) 与 AMCN 一起使用。所提出的技术可以减少 AOWC 中泵浦光源的数量。本文论证了光源数量的减少以及利用泵浦光传播进行波长转换的可行性。我们计算了使用 RP-AOWC 所导致的泵浦源数量和收发器类型数量的减少，并利用泵浦光传播进行波长转换实验。
Access-metro convergence networks (AMCN) have been proposed as a future optical communication network to realize flexible and dynamic bandwidth allocation. An AMCN requires transceivers with different wavelengths for the optical network units (ONUs). This causes an increase in production costs. Although an all-optical wavelength converter (AOWC) mitigates this issue, the AOWC increases the installation cost because it consists of many expensive optical devices. We propose the use of a remotely pumped AOWC (RP-AOWC) with an AMCN. The proposed technique can reduce the number of pump light sources in the AOWC. This paper demonstrates this reduction in the number of light sources and the feasibility of wavelength conversion using pump light propagation. We calculate the reduction in the number of pump sources and the number of transceiver types caused by the use of RP-AOWC and experiment with the wavelength conversion using pump light propagation.
