Fiber-to-the-antenna (FTTA) system can be a cost-effective technique for distributing high frequency signals from the head-end office to a number of remote antenna units via passive optical splitter and propagating through low-loss and low-cost optical fibers. Here, we experimentally demonstrate an optical ultra-wideband (UWB) - impulse radio (IR) FTTA system for in-building and in-home applications. The optical UWB-IR wireless link is operated in the W-band (75 GHz - 110 GHz) using our developed near-ballistic unitraveling-carrier photodiode based photonic transmitter (PT) and a 10 GHz mode-locked laser. 2.5 Gb/s UWB-IR FTTA systems with 1,024 high split-ratio and transmission over 300 m optical fiber are demonstrated using direct PT modulation.
光纤到天线（FTTA）系统可以是一种经济高效的技术，用于通过无源光分路器将高频信号从前端办公室分配到多个远程天线单元，并通过低损耗和低成本的光纤进行传输。在此，我们通过实验演示了一种用于室内和家庭应用的光学超宽带（UWB）-脉冲无线电（IR）FTTA系统。光学UWB-IR无线链路在W波段（75GHz - 110GHz）运行，使用我们开发的基于近弹道单载流子光电二极管的光子发射器（PT）和10GHz锁模激光器。通过直接PT调制，演示了具有1024高分光比且在300m光纤上传输的2.5Gb/s UWB-IR FTTA系统。
