We demonstrate quantum key distribution (QKD) with bidirectional 10 Gb/s classical data channels in a single fiber using dense wavelength division multiplexing. Record secure key rates of 2.38 Mbps and fiber distances up to 70 km are achieved. Data channels are simultaneously monitored for error-free operation. The robustness of QKD is further demonstrated with a secure key rate of 445 kbps over 25 km, obtained in the presence of data lasers launching conventional 0 dBm power. We discuss the fundamental limit for the QKD performance in the multiplexing environment.

• Practical challenges in quantum key distribution (2016, unknown): “First, QKD systems have been shown to coexist with intense data traf fi c in the same fi bre, 64 – 67 thus eliminating the need for dark fi bres that are not only expensive but also often unavailable.”
• Secure quantum key distribution (2014, background): “As mentioned in the introduction, researchers are working on designing and building high-speed QKD systems [61] and the ability of multiplexing strong classical signals with weak quantum signals in the same optical fibre [62–64].”
