Optical CDMA is a flexible technology for efficient and scalable multiple access networks. It also offers increased physical layer privacy and on-demand bandwidth sharing management. Highly scalable approach to incoherent OCDMA system was developed and demonstrated. Error-free operation with a BER less than 10-12 including complete elimination of the MAI noise was achieved using 2ps time gating. The approach introduces a negative power "penalty" which helps to improve an overall system power budget and performance. It is shown that two picosecond time gate can significantly improve number of simultaneous users in the system by more than tree times without any degradation of BER.
