我们报告了一个宽带（370-2500 MHz）分布式天线系统（DAS），它使用可插拔模拟光收发器的基础上，行业标准的小型可插拔（SFP）格式。可插拔光学器件的使用具有许多优点，例如热插拔性、可插拔性和低初始成本，其在数字世界中已经开发了数年，但尚未对模拟应用进行相同程度的研究。除了与RF信号无关的宽带系统之外，通过简单地改变收发器模块，该系统还可以在不同类型的光纤（SMF和MMF）或同轴电缆上操作
We report a wideband (370-2500 MHz) distributed antenna system (DAS) which uses pluggable analogue optical transceivers based on the industry standard small form-factor pluggable (SFP) format. The use of pluggable optics has a number of advantages such as hot-swappability, upgradeability and low initial cost, which has been exploited in the digital world for several years but has not been investigated to the same extend for analogue applications. In addition to the wideband system being RF signal agnostic, the system can also operate over different types of fibre, both SMF and MMF, or coaxial cable, by simply changing the transceiver module
