Crosstalk accumulates as optical packets pass through imperfect WDM components, resulting in performance degradation. In this paper, we investigate and analyze how inband crosstalk is generated and accumulated in wavelength-routing based photonic packet buffers (WRPPB’s). It is found that the number of inband crosstalk arising from the WRPPB buffer can be approximated by a binomial distribution. The impact of inband crosstalk on the bit-error-rate performance is also examined.
