This letter presents a subcarrier multiplexing with spread spectrum (SCM-SS) scheme for optical multiple-input multiple-output (MIMO) transmission over multimode fibers. Optical MIMO is dedicated to increasing link capacity by exploiting the space domain, which provides a new dimension in addition to conventional time division multiplexing (TDM) and wavelength division multiplexing (WDM). SCM-SS scheme is a promising way that avoids resolving channels in optical domain, and multiple channels are recovered by off-line MIMO signal processing. Up to 2000m transmissions of 100Mbps per channel 2×4 MIMO over graded index multimode fiber link with direct detection have been experimentally demonstrated. Advantageous performance in the presence of intermodal coupling is shown.
