Distortion of the OCDMA auto-correlation width by fiber chromatic dispersion can severely influence incoherent OCDMA transmission based on picosecond multi-wavelength pulses. To the best of our knowledge, we report for the first time the use of SOA for manipulation of the OCDMA auto-correlation consisted of multi-wavelength code carriers in order to provide needed compensation. The OCDMA transmission system was based on two- dimensional wavelength-hopping time-spreading (2D-WH/TS) codes with 8 ps multi-wavelength pulses as the code carriers. Different techniques deploying SOA for auto-correlation width adjustment were investigated and their effectiveness was subsequently verified on the OCDMA transmission through a 17 km long fiber optic testbed connecting Strathclyde and Glasgow Universities.
