Crosstalk accumulates as optical packets pass through imperfect wavelength-division-multiplexing components, resulting in performance degradation. We investigate and analyze how inband crosstalk is generated and accumulated in wavelength-routing-based photonic packet buffers (WRPPB). We show that the number of inband crosstalk elements arising from the WRPPB buffer can be approximated by a binomial distribution and examine the impact of inband crosstalk on the bit-error rate and the power penalty.
