We demonstrate 10-Gb/s, 80-km-reach RSOA-based WDM PON by utilizing the digital coherent detection and electronic phase equalization techniques. The upstream signal is obtained by directly modulating a TO-can packaged RSOA with 10-Gb/s QPSK signal.
We review the recent progresses in the coherent detection techniques developed for the use in the optical access network. To enhance the cost-effectiveness, we implement the coherent receiver by utilizing a portion of the seed light as a local oscillator and a 3×3 coupler as a 120° optical hybrid. In addition, instead of using the complicated polarization-diversity receiver, we achieve the polarization...
