Implementing QKD over Multi-Fiber Ribbon Cables: How Dark is the "Dark Fiber"?

Year: 2026

Type: conference-paper

Abstract: We identify inter-lane crosstalk as main cause for QKD degradation in 1×12 bend-loss insensitive fiber ribbon cables. Despite allocating QKD to unused fiber lanes, neighboring classical signals can lead to total saturation of single-photon detectors.
