It is demonstrated that the bandwidth limitation of multimode fiber links arising from modal dispersion can be overcome by using passband modulation in the frequency range beyond the 3-dB bandwidth. Transmission of 1.25 Gb/s over 500 m of near-worst case 62.5-μm multimode fiber is achieved using two subcarrier multiplexed channels at the 850-nm wavelength.
