Describes Locnet, an experimental system designed to investigate optical switching. The narrow- and mid-band regions of the local optical communication system are constructed as a star network with decentralised switching, TDMA, and a single-mode star-connector operating as an optical bus. LiNbO3 switching is incorporated, to help prevent interference and crossed lines. Static measurements, dynamic signals and the problems encountered under system operation are discussed.
