Abstract
With the rapid increase of the PON data rate, it becomes more and more challenging to meet the system requirement, such as power budget, while still satisfying the aggressive cost target for the PON system. In addition, it is worth looking at potential technologies for the next generation system beyond 50 Gbit/s. Both academia and industry have started to look into new enabling technologies to help improve the system performance compared to the previous generation, while not dramatically increasing the system cost. Among all the novel enabling technologies, digital signal processing (DSP), coherent detection, and photonic integration have great potentials to be adopted in PON-based systems to enable rapid traffic growth, which will be discussed in detail through this chapter.
