We investigate the integration of quantum key distribution (QKD) into classical optical communication links based on a field-deployed uncoupled-core four-core fiber. We experimentally characterize inter-core spontaneous Raman scattering (IC-SpRS) and evaluate the impact of IC-SpRS and dark counts on QKD performance as the classical traffic load is varied when three cores are used for classical WDM transmission and one for QKD.

Abstract
We investigate the integration of quantum key distribution (QKD) into classical optical communication links based on a field-deployed uncoupled-core four-core fiber. We experimentally characterize inter-core spontaneous Raman scattering (IC-SpRS) and evaluate the impact of IC-SpRS and dark counts on QKD performance as the classical traffic load is varied when three cores are used for classical WDM transmission and one for QKD.File in questo prodotto:
