Abstract: Based on fiber Bragg gratings as encoder/decoder,the effect of group-velocity mismatch of the optical fiber is analyzed in FH-OCDMA system. The normal single mode optical fiber is not available for FH-OCDMA system without any compensation scheme.A group-velocity compensation scheme is also proposed to fulfill the FH-OCDMA system.

Key words: OCDMA, frequency hopping system, group-velocity mismatch, fiber Bragg gratings
