The last mile solutions for high-speed high-capacity optical networks capable of securely supporting large number of simultaneous users by minimal hardware requirements are needed but it seems that any such solutions are still far away. Access networks based only on a wavelength-division multiplexing (WDM), optical timedivision multiplexing (OTDM) or optical code-division multiplexing (OCDM) schemes...
This paper presents results of our extensive investigation of OCDMA system performance under the influence of varying transmission link chromatic dispersion. The investigations were carried out using incoherent 2-dimensional wavelength-hopping/time-spreading (2D-WH/TS) OCDMA codes based on picosecond pulses on a 17 km long bidirectional fiber link installed between the Strathclyde and Glasgow University...
