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.

基于WDM-PON的接入-地铁融合的远程泵浦全光波长转换

城域汇聚网络（AMCN）已经被提出作为未来的光通信网络，以实现灵活和动态的带宽分配。AMCN要求光网络单元（ONU）具有不同波长的收发器。这导致生产成本增加。尽管全光波长转换器（AOWC）可以缓解此问题，但AOWC会增加安装成本，因为它由许多昂贵的光学设备组成。我们建议与AMCN一起使用远程泵送的AOWC（RP-AOWC）。所提出的技术可以减少AOWC中泵浦光源的数量。本文证明了这种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。
