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.

点对点强度调制和直接检测灵活收发器，结合级联快速傅里叶逆变换/基于快速傅里叶变换的多通道聚合/解聚合技术

点对点 (P2P) 灵活收发器是关键技术推动者，可为远程设备控制和分布式光纤网络等各种应用经济高效地提供快速、动态且“尺寸恰到好处”的超密集 P2P 连接。然而，最初为中心辐射型流量模式设计的现有灵活收发器并不是最优的。为了有效解决这一技术问题，提出了一种结合了级联逆快速傅里叶变换/基于快速傅里叶变换的多通道聚合/解聚合技术以及模拟同相和正交（IQ）混频器的P2P灵活收发器，并进行了数值评估。 56Gbps@20公里强度调制和直接检测传输系统。所提出的 P2P 灵活收发器不仅支持通道数和通道线路速率的自适应和灵活变化，而且还提供额外的物理层网络安全性。
