An ultra-dense scheme is used to set the limits for the technology and a strategy for minimizing inter-channel nonlinear crosstalk is proposed.

This characterization is based on frequency response and time domain reflectometry measurements performed at local loop under test.

With 2x8x10 Gb/s over 50 km, the performance is evaluated for various pulse roll-off factors.

Both transmitters/receivers implemented in FPGA use a simple 8-bit DSP architecture. An optimal transmitted power of -7 dBm per channel is achieved for 50 km, 1:16 split and 2.5 GHz grid.

This technique is based on positioning and characterizing a probe channel which is further analyzed. This analysis leads to an estimation of the nonlinear distortion in the system which in turns could be used for instance to optimize the system performance. This technique is validated through simulation results.

The paper first presents technical issues regarding digital implementation of Nyquist spectral shaping for low-symbol-rate systems. Second, the potential benefits regarding mitigation of cross talk (linear and nonlinear) of Nyquist pulse shaping in symmetric and bidirectional wavelength-division multiplexing passive optical networks (WDM-PONs) are presented. Lastly, the paper proposes a WDM-PON solution employing self-coherent detection at the optical network unit and heterodyne coherent detection at the optical line terminal. In this proposed architecture, a multi-objective optimization strategy is developed to enhance the transmission performance of the Nyquist-shaped bands in full-duplex mode.
