Abstract

In this paper we demonstrate the application of multi-user quantum key distribution (QKD) to typical broadband fibre-based passive optical access links to metropolitan area networks. We propose a technique to utilize the currently unused 850nm waveband in standard telecommunications fiber for QKD in two network architectures. Net bit rates of up to 100's of kilobits^-1 were achieved for each receiver, depending on the network topology. The transmission distances between sender and receivers were compatible with the typical span of optical access links (= 10km).
