A novel structure has been designed for bit synchronization in a terabit-per-second optical interconnection network with adjustable op tical delay lines, The two-stage network consists of 1024 optical links connected to a central switching module. A distributed optical clock net-work is designed for bit synchronization at each node computer. Zero link setup time can be achieved by precisely matching the phases of each pair of clock and signal, The link-to-link switching time can be reduced to less than 20 ns in the two-stage network. Even in a three-stage network that can accommodate 32.768 optical links, the link switching time can be maintained below 30ns. At the same time, a total bidirectional band-width of 98304Tbit/s can be obtained. Since bit synchronization is achieved entirely in the optical domain, this structure is independent of link transmission rates.
