Paper Abstract

As the demand for higher capacity and longer reach of optical access networks is garnering momentum in recent years, coherent access technology attracts renewed interests in high-capacity optical networking. In this paper, designs of various coherent access networks are investigated and compared. From our results, it may be the most promising solution with high capacity at optimized cost. When coherent detection is employed in access network, the laser linewidth is a key design issue for optimized performance and cost as laser phase noise is larger with lower bit rate. One of our objectives is to examine the feasibility of employing a conventional DFB as carrier sources. We evaluated the performance of ultra-dense WDM access networking system. Experimental results show that 2.5GB/s QPSK data can be transmitted over 35-km SMF-28 with 6.5GHz channel spacing using DFB lasers.
