Paper Abstract

In self-routing packet networks, the state of intermediate nodes (switches) is set or reset on the basis of the information present in the packet header. Subcarrier multiplexing (SCM) modulates a number of frequency-separated RF sub-carriers onto a common laser at a single wavelength. SCM has the advantage of high data throughput. It also requires fewer opto-electronic components and avoids walk- off between header and payload due to fiber dispersion. In this paper we describe a novel use of sub-carrier multiplexing for self-routing of data packet within the switching fabric of a high performance system area network. Using SCM data packets are routed optically to the destination without being converted to the electrical domain at the intermediate stages within the network.
