VITA Architectures for Optical Study GroupVITA members recognize the need for higher density, higher performing interconnect technologies to meet the speeds of 10 gigabit serial channels and higher that will be used in next generation critical embedded systems. As the transfer rates continue to increase, it is clear that optical technology offers many advantages. Since optical interconnects work best as a point-to-point connection, future systems are going to need much higher density supporting hundreds of connections in a single board or line-replaceable unit (LRU). Achieving the projected level of combined performance and connector density is no easy challenge. The lead-time to develop technologies and supporting specifications is very long. To that end, VITA is launching a study group now to research potential technologies and propose an architecture that could become part of future solutions. MissionThe mission of the VITA Architectures for Optical Study Group is to research and determine the feasibility of developing a standard architecture for optical interconnects suitable for deployment in critical embedded systems. The study group will focus on high-density options for backplanes and connections between line-replaceable units, mezzanines, and daughter cards. Critical embedded systems are high-performance, distributed computing systems, and they manage high bandwidth I/O; involve real-time processing; and are environmentally constrained in size, weight, and power (SWaP). The study group will explore the needs and ascertains the interest in developing a standard. The study group can move to working group status by meeting defined working group formation criteria as defined by the VITA Standards Organization. Existing standards and those under development by Standards Developing Organizations (SDOs), and appropriate industry alliances, community collaboration efforts, and other groups will be used whenever practical. The Study Group will proactively reach out to such groups to facilitate their early involvement. Individuals and companies that are interested in participating should contact The VITA executive director, Subject: VITA Architectures for Optical Study Group. New material will be posted here as discovered by the Study Group.
