Abstract

The research proposal to PITE-2 Fapesp involving Unicamp and the Brazilian company Padtec aims new achievements on capillarity and spectral efficiency of Optical Networks. The spectral efficiency in the spatial dimension will be enhanced through simulations with experimental validation for up to 4 channels, including non-linear effects partial compensation. The spectral efficiency compression will be enhanced by using flexgrid superchannels with OFDM (orthogonal frequency-division multiplexing) and/or Ny-WDM (Nyquist WDM), based on low-cost lasers. Spectral efficiency will be also improved using up to 64 QAM (quadrature amplitude modulation) modulation format with dual polarization (DP), studying the limits of up to 56 Gbaud channels in relation to optical signal-noise ratio (OSNR) and new forward error correcting codes (FEC). Offline digital signal processing (DSP) simulations will include recovery algorithms for Reconfigurable FPGA (field programmable gate array) with HTML (hyper text markup language). Capillarity will be explored theoretically by studying new architectures of ROADMs (reconfigurable optical add-drop multiplexers) with concatenated WSS (wavelength-selective switches). Finally, capillarity increase will be tested in broadband channel sharing by using optoelectronic switching with an emphasis on electromagnetic interference between the differential edge-coupled strip- lines in up to 28 Gbit/s, in printed circuit boards with up to 50 layers and 2,200 lines.)
