Next generation passive optical network (NG-PON), which aims at providing cost-effective solutions to the ever-increasing bandwidth demand of the end-customers with data rate of 100-Gb/s, is attracting more and more attentions. In this paper, a symmetric 100-Gb/s DSP-enhanced TWDM-PON architecture with four pairs of wavelengths is proposed. 4×25-Gb/s TWDM-OFDM-PON is experimentally demonstrated over...
Recently, digital signal processing (DSP) methods have attracted a lot of attention for next-generation passive optical network (PON). To achieve high spectrum-efficiency colorless transmission, we combine the time-division-multiplexing (TDM) architecture with advanced DSP methods to propose a DSP-enhanced TDM-PON, in which DSP-based symbols are transmitted in different time slots instead of on-off-key...
