Abstract :
A concept for distributed ultra-dense frequency-division multiplexing is presented which enables precise frequency allocation without the need of absolute optical frequency control at the multiplexing nodes. We review experiments with OFDM and zero-guard-band Nyquist-WDM to demonstrate the precise generation of superchannels.
