We report successful transmission of dual-LP11 mode (LP11a and LP11b), dual-polarization coherent optical orthogonal frequency division multiplexing (CO-OFDM) signals over two-mode fibers (TMF) using all-fiber mode converters. Mode converters based on mechanically induced long-period grating with better than 20 dB extinction ratios are realized and used for interfacing single-mode fiber transmitters and receivers to the TMF. We demonstrate that by using 4x4 MIMO-OFDM processing, the random coupling of the two LP11 spatial modes can be successfully tracked and equalized with a one-tap frequency-domain equalizer. We achieve successful transmission of a 35.3-Gb/s CO-OFDM signal over 26-km two-mode fiber with less than 3 dB penalty.
