Abstract

In this contribution we present reasons for sharing the fibres by both Quantum key distribution and telecommunication traffic, we describe possible sources of noise, discuss availability of photodetectors. Based on these facts we propose suitable wavelength band and verify injection of such Quantum key distribution signal into telecommunication fibre with no impact to transmission system performance.
