Enabling Shortwave-QKD in Short-Reach Networks: Impact of a Composite ODN Native to Telecom Applications

Abstract

We deploy shortwave-QKD over short-reach in-house/datacom architectures and show that few-mode propagation and speckle-selective loss severely impact the QKD performance. We accomplish 12 kb/s secure-key generation in presence of 50 co-existing data channels.
