本文提出了一种动态多频带OFDM子载波分配方案，在色散和啁啾相关的功率衰落的限制下，充分利用可用带宽。实验结果成功地证明了强度调制直接检测34.78 Gbps的OFDM信号传输100公里长距离（LR）的无源光网络（脑桥）的基础上，具有成本效益的10 GHz的EAM和10 GHz的PIN。考虑到10 GHz EAM的0-100 km传输带宽，理论上估计最窄带宽出现在约40 km处，而不是100 km处。因此，实验研究了20-100-km脑桥的性能，并且实现了至少33-Gbps的容量以支持所有可能的20-100-km半径的LR-PON。
We develop a dynamic multi-band OFDM subcarrier allocation scheme to fully utilize the available bandwidth under the restriction of dispersion- and chirp-related power fading. The experimental results successfully demonstrate an intensity-modulation-direct-detection 34.78-Gbps OFDM signal transmissions over 100-km long-reach (LR) passive-optical networks (PONs) based on a cost-effective 10-GHz EAM and a 10-GHz PIN. Considering 0-100-km transmission bandwidth of a 10-GHz EAM, the narrowest bandwidth is theoretically evaluated to occur at ~40 km, instead of 100 km. Consequently, the performances of 20-100-km PONs are experimentally investigated, and at least 33-Gbps capacity is achieved to support LR-PONs of all possible 20-100-km radii.
