This leads to a increase in demand for bit rate upgrade and technology evolution of the network infrastructures. For access networks, cost- and power-effectiveness are the highest priority for the bit rate upgrade. The EU project CEEOALAN (No: 623515) aims to identify and demonstrate modulation formats together with low complex DSP for high speed 40-Gb/s per lambda NG-PONs. DSP is vital for enabling a practical low-cost realization of high-speed NG-PON, without changing the optical infrastructure. This work offers the first detailed numerical analysis and comparison between each format in achievable link power budget performance and DSP complexity. Important findings include that the DSP is economically viable through optimizing equalization for access networks and that the choices of proper modulation format and DSP configuration depend on the transmission distances of interest.
