Paper Abstract

This paper describes the development of a prototype onboard baseband switch for use in advanced satcom systems. The modular switch is designed to accommodate different types of satcom services and/or carriers. The selected architecture utilizes a high-speed fiber optic ring for the I/O interconnections of the satcom channels handling both circuit- and packet-type traffic. Whereas, an optical star topology is used for onboard clock distribution. The onboard baseband switch design makes maximum use of photonics, VLSI, and standard cell/gate array technologies to implement the hardware/firmware required for a power-efficient, light-weight, reliable payload with a flexible switch architecture. Relevant optical technologies, active and passive components, and systems considerations to ensure a high reliability operation are discussed. To assess its viability in potential commercial applications, the state-of-the-art of photonics technology and future prospects for economical large capacity multi-channel services are briefly reviewed.
