We describe a novel all-optical hybrid mode-division multiplexing (MDM) -optical code division multiplexing (OCDM) architecture for future flexible access network. We successfully demonstrate, for the first time, an asynchronous on-off keying (OOK) modulation, 2 mode x 4 code x 10 Gbps transmission over 2km two mode fiber (TMF), without dispersion compensation at single wavelength, by using 16-chip (200 Gchip/s), 16-phase-shift keyed (PSK) optical codes (OC) generated by a multiport encoder/decoder (E/D) and an optical mode multiplexer/demultiplexer (MMUX/MDeMUX). We also analytically and experimentally evaluate the mode crosstalk tolerance as a function of the LP01 and LP11 modes.
