Abstract
In this paper, we propose construction method of new two-dimensional (2-D) codes where one-coincidence frequency hopping code (OCFHC) is used for wavelength assignment and congruence codes (CCs) for time slot assignment. The performance evaluation of the OCFHC/quadratic congruence code (OCFHC/QCC) is made in presence of atmospheric turbulence and various weather conditions. Lognormal model is used for weak turbulence and gamma-gamma model for moderate and strong turbulence conditions. Various weather conditions like thick fog, light fog and very clear air are considered in the evaluation.
