摘要

我们提出并演示了一种用于DWDM毫米波光纤无线电系统的上游传输方案，该方案具有改进的功率预算。SOA结合AWG同时放大下行链路RF子载波和光载波，分别出现在AWG的奇数和偶数端口，从而提高下行链路的载波与边带比。偶数端口的光载波被重新用于上游传输，从而提供无激光的BSs。实验结果表明，该方案可用于未来的双向WI-DWDM传输系统。

Improved power budget for uplink transmission using SOA for fiber-radio systems

We have proposed and demonstrated an upstream transmission scheme with improved power budget for DWDM millimetre-wave fiber-radio systems. An SOA in conjunction with an AWG simultaneously amplify the down link RF subcarriers and optical carriers appearing at odd and even numbered ports of the AWG respectively, thus improving the carrier-to-sideband ratio in the downlink. Optical carriers at even numbered ports are re-used for upstream transmission thereby providing laser free BSs. Our experimental results shows that proposed scheme can be a practical solution for future bidirectional WI-DWDM transmission systems.
