Performance evaluation of spectral amplitude codes for OCDMA PON
In this paper, we present a performance evaluation of three codes; enhanced double weight (EDW), random diagonal (RD) and zero cross correlation (ZCC) for 10 Gb/s x 4 user, 20 km standard SMF transmission link for OCDMA PON. These SAC codes have ideal in-phase cross-correlation properties to reduce...

| Summary: | In this paper, we present a performance evaluation of
three codes; enhanced double weight (EDW), random diagonal
(RD) and zero cross correlation (ZCC) for 10 Gb/s x 4 user, 20
km standard SMF transmission link for OCDMA PON. These
SAC codes have ideal in-phase cross-correlation properties to
reduce the MAI effects in OCDMA. The performance has been
characterized through received optical power (ROP) sensitivity
and dispersion tolerance assessments. The numerical results
show that the ZCC code has a slightly better performance
compared to the other two codes for the ROP and similar
behavior against the dispersion tolerence. In the analysis we also
consider the character of the code properties and the flexibility as
criteria for OCDMA PON network instead of the performance. |
