摘要

在无源光网络中使用分布式反馈激光器需要特定的架构和适当的算法来进行微调和频谱管理。这些算法可以在简单的单模激光器上实现，使用带有控制结构的热闭环和2x2预均衡级;在超密集波分复用场景下，波长和光功率精确调谐，振荡可以忽略不计。

DFB Tuning Functions in Coherent PONs.

The use of Distributed FeedBack lasers for Passive Optical Networks requires specific architecture and appropriate algorithms for fine tuning and spectrum management. These algorithms can be implemented over simple single-mode lasers using thermal closed-loop with a control structure and 2x2 pre-equalization stage; the wavelength and optical power are tuned precisely with negligible oscillations for channels spaced 6.25 GHz under an ultra-dense-wavelength-division-multiplexing scenario.
