title: Weighting nonlinearities on future high aggregate data rate PONs.
abstract: In this paper we address high aggregate data rate coherent UDWDM-PONs (ultra-dense wavelength-division multiplexing passive optical networks) related physical impairments. Firstly, analog to digital converter resolution and laser linewidth are optimized giving the minimal signal to noise ratio penalty for UDWDM-PON systems at 10 Gb/s per user/wavelength. Secondly, inter-channel nonlinearities impact on high-order modulation formats at 1-2.5 Gb/s per channel and 100 km-reach is studied by means of Volterra series simulations.
