Abstract

We propose and demonstrate a new sub-carrier multiplexing scheme, utilizing orthogonal, periodic-sinc-shaped sub-carrier spectra. This 'folded' OFDM allows for multi-carrier bands to be generated with the precise, rectangular frequency definition of Nyquist WDM. We show that this scheme can be implemented with 10 GHz sub-bands, showing a 0.5-dB implementation penalty and successful transmission over 4160-km. We further investigate 40-GHz bands in an add/drop multiplexing scenario on a 50-GHz WDM grid, and show that folded OFDM can provided advantages over conventional OFDM in bandwidth-limited systems.
