A multiwavelength optical interconnection architecture for parallel-processing computers is presented. This fully connected, internally nonblocking network, using tunable lasers, requires only two optical fibres per node. Wavelength switching measurements (access times <20ns) and calculated throughput are presented. Critical target parameters are established for optical device development.

Inspec keywords: optical waveguide components; frequency division multiplexing; parallel architectures; parallel machines
