Abstract
This paper describes the dual-layer scalable optical interconnection networ k being developed at Tianjin University. The top layer of the network is a multiwavelength bidirectional optical bus, which has large bandwidth and lo w latency. The bus is made up of passive components. No wavelength-tunable devices are used. As a result, the bus has a low communication latency that is mainly determined by the optical fiber length. The sublayer of the netw ork is a single-wavelength ring, which has low communication latency and hi gh scalability. In each ring, a wavelength routing node is designed for dat a transmission between the ring and the optical bus. Each node computer is connected to the ring through an optical network interface card. The commun ication latency inside the ring is decreased by using synchronous pipelinin g transmission. (C) 2001 Society of Photo-Optical Instrumentation Engineers .
