Open optical networks present a variety of benefits to service providers and enterprise network operators, such as freedom from single-vendor dependence and the potential to select best-in-class solutions for each individual network role (e.g., line system or optical terminals). In this paper, we discuss two open optical network models: one enables transponder–line system interoperability, whereas the other goes a step further and enables line system–line system interoperability. We examine these models in more detail in the context of an open optical system already deployed at scale. We present real-world experiences and lessons learned with respect to optical link design, software and controls, deployment, and operation, as well as recommendations for future evolution of the network.

在超大规模运营商处开放光通信系统[已邀请]

开放的光网络为服务提供商和企业网络运营商带来了多种好处，例如摆脱了对单一供应商的依赖，并有可能为每个单独的网络角色（例如，线路系统或光终端）选择同类最佳的解决方案。在本文中，我们讨论了两个开放的光网络模型：一个启用转发器与线路系统的互操作性，而另一个则更进一步，实现了线路系统与线路系统的互操作性。在已经大规模部署的开放光学系统的背景下，我们将更详细地研究这些模型。我们将介绍有关光链路设计，软件和控制，部署和操作方面的实际经验和教训，并为网络的未来发展提供建议。
