Abstract

Multi-band transmission is attracting the interest of research community because of its prospects to increase network infrastructures life. Indeed, current deployed systems mainly exploit the C band, thus deployed fibers can still offer a wide range of available spectrum. In this paper, quality of transmission (QoT) estimation is considered as fundamental control step for light path setup in order to check the proper feasibility of transmission along a computed light path. We demonstrate multi-band networking with channels on C and S bands in a testbed including a re-circulating loop. As a QoT estimator, the open-source GNPY module is extended in order to consider the typical impairments of a long-haul multi-band transmission and validated in this multi-band scenario for assisting connection setup with quality of transmission estimation. The measurements on the testbed demonstrated the correct operations of the multiband data plane testbed, particularly with reference to the GNPy estimations and thus validate the QoT estimator for C+S band transmission.

GNPy辅助多波段光网络的实验验证

多频带传输因其具有提高网络基础设施寿命的前景而引起了研究界的广泛关注。事实上，目前部署的系统主要利用C波段，因此部署的光纤仍然可以提供广泛的可用频谱。本文将传输质量(QoT)估计作为光路设置的基本控制步骤，以检验沿计算光路传输的可行性。我们演示了C和S波段信道的多波段网络，包括一个再循环回路。作为QoT估计器，开源GNPY模块经过扩展，以考虑长途多频段传输的典型缺陷，并在该多频段场景中进行验证，以协助连接设置和传输质量估计。测试平台上的测量证明了多波段数据平面测试平台的正确操作，特别是参考GNPy估计，从而验证了C+S波段传输的QoT估计器。
