A Crosstalk-Minimized Wavelength Conflict Avoiding Algorithm for Optical Switching in Quantum - Key-Distribution Optical Networks

We proposed a wavelength conflict avoiding algorithm in quantum key distribution optical networks (QKD-ON) with multi-core fibers. The proposed algorithm minimizes the crosstalk in the switching process and improves the successful switching probability of requests by constructing the crosstalk auxiliary graph. Simulation results show that blocking probability is greatly reduced.
