Abstract

We present the application of quantum key distribution (QKD) technologies to fiber-based broad-band passive optical access networks. This application is based on our 850-nm wavelength gigahertz clock-rate single-receiver system, is compatible with existing telecommunications fiber and exploits a wavelength band not currently utilized in access networks. The developed QKD networks are capable of transmitting over distances consistent with the span of access links for metropolitan networks (10 km), at clock frequencies ranging up to 3 GHz
