A novel hybrid electrical optical Clos switch network for multiprocessor cluster system was presented. For multiprocessor cluster system of 128 hosts, the novel optical Clos network includes 16 basic modules, a passive optical fiber backplane with (8×15)×16 which has a total of 1920 optical data channels and a signaling control system. The basic module is composed of the input line cards of 8 hosts, a single chip of 16×16 crossbar switch, parallel transmitting VCSEL modules for fan-out of (16-1)optical fiber channels and (16-1)×1 optical combiners. The passive optical fiber backplane of very large capacity and high density, based on linear VCSEL arrays and fiber ribbon technology, is to be used to interconnect between hosts of different sub-clusters. The routing of the optical Clos switch network is decided by a signaling control system. Compared with high performance electronic system, this technology offers a relatively easy and simple means of communicating large amount of information between hosts, and lower delay time.
