Abstract

Optical encoders/decoders based on fiber gratings are designed and fabricated. Experiment on one interference user 2.5Gb/s symbol overlapping optical fast frequency-hopping CDMA (SO-FFH OCDMA) system is demonstrated. Multiaccess interference in SO-FFH OCDMA system is studied, and is compared with that of traditional FFH OCDMA system. Experiment result shows that multi-access interference will degrade the system performance. With one interference user, SO-FFH OCDMA can also decode data correctly at data bit rate 2.5Gb/s.
