Abstract
Group velocity walk-off effect on frequency hopping optical code division multiple access (FH-OCDMA) system is analyzed. We develop a systematic method which employs transfer function considering encoder, fiber channel and decoder to analysis the FH-OCDMA system. The difference of group velocities affects system performance more seriously than dispersion effect. The results show that single mode fiber is not proper for the FH-OCDMA system even the transmission length is no more than 1 kilometer while the dispersion-shifted fiber is more suitable for FH-OCDMA system.
