A Scalable and Modular Optical Interconnection Network for A Terabit Packet Switch

摘要

In this paper, an optical bufferless interconnection network is proposed. Due to its modular architecture and the use of the advanced wavelength-division-multiplexing technology, the proposed optical intereconnection network can be scaled up in the range of terabit per second. In this paper, we present its architecture and component complexity as a function of the number of wavelengths. In addition, we also analyse its power budget, and evaluate the crosstalk caused by the finite ON-OFF ratio of optical switching gates. Bit error rate with respect to different ON-OFF ratios and extinction ratios are evaluated by simulations. The results show that it is feasible to construct a 256x256 optical interconnection network with existing state of the technology.
