Abstract

Point-to-point (P2P) flexible transceivers are the key technical enabler to cost-effectively offer fast, dynamic, and ‘just-the-right-size’ ultra-dense P2P connectivity for various applications including remote equipment control and distributed fibre networks. However, existing flexible transceivers originally designed for hub-and-spoke traffic patterns are sub-optimal. To effectively address such technical issue, a P2P flexible transceiver incorporating a cascaded inverse fast fourier transform/fast fourier transform-based multi-channel aggregation/de-aggregation technique and analogue in-phase and quadrature (IQ) mixers is proposed and numerically evaluated in a 56Gbps@20 km intensity modulation and direct detection transmission system. The proposed P2P flexible transceivers not only support adaptive and flexible variations in both channel count and channel line rate but also offer additional physical layer network security.

采用级联反快速傅里叶变换/基于快速傅里叶变换的多通道聚合/去聚合技术的点对点强度调制和直接检测柔性收发器

点对点（P2P）灵活收发器是为远程设备控制和分布式光纤网络等各种应用提供快速、动态和 "恰到好处 "的超密集 P2P 连接的关键技术。然而，现有的灵活收发器最初是为集线器和辐条流量模式设计的，并不理想。为有效解决这一技术问题，我们提出了一种 P2P 柔性收发器，它采用了基于级联快速傅立叶变换/快速傅立叶变换的多通道聚合/去聚合技术和模拟同相正交（IQ）混频器，并在 56Gbps@20 千米强度调制和直接检测传输系统中进行了数值评估。所提出的 P2P 灵活收发器不仅支持信道数和信道线速的自适应灵活变化，还提供了额外的物理层网络安全性。
