摘要

我们提出并演示了一种波长重调制的WDM-PON，由反射半导体光放大器(rsoa)实现，使用4B/5B和4B/6B线码，具有比曼彻斯特码更高的编码效率，用于下游调制。实验结果表明，4B/5B和4B/6B线路码允许使用不饱和rsoa作为上游重调制器，与NRZ码相比，提高了功率预算。

Line Coding for Downstream Modulation in a RSOA-Based Wavelength Re-Modulated WDM-PON

We propose and demonstrate a wavelength re-modulated WDM-PON implemented by reflective semiconductor optical amplifiers (RSOAs) using 4B/5B and 4B/6B line codes, which have higher coding efficiency than Manchester code, for downstream modulation. The experimental results show that 4B/5B and 4B/6B line codes allow using unsaturated RSOAs as upstream re-modulator, thus improving power budget compared with NRZ code.
