Real-time Bi-directional 10GbE transmission using MIMO-less space-division-multiplexing with spatial modes

Bi-directional transmission using MIMO-less space-division-multiplexing with spatial modes is experimentally demonstrated. 10GbE real-time data-streams are bi-directionally transmitted error-free (<;-22.0dB mode crosstalk) using LP01↔LP11° and LP11°↔LP11e modes over a 0.5km, elliptical-core, few-mode optical fiber full-duplex.
