Scottsdale, Az. – VITA has just announced the formation of the Architectures for Optical (VAO) Study Group that will be researching high density optical interconnect technology and developing a proposal for next generation architectures for critical embedded systems.
A call for participation in the study group goes to non-VITA members to make presentations and participate in discussions with the Study Group. A study group is the initial step in the process of developing an ANSI/VITA standard.
According to Ray Alderman, executive director of VITA, it is recognized within the community that there is a 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, he said, 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.” said Alderman. “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.
“VITA recognizes the challenges with optical technology and feels that work needs to begin now to ensure the right solutions in the future. VITA anticipates that systems in the future will depend heavily on cost effective high density optical interconnect technology.”
The 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).
A study group explores the needs and ascertains the interest in developing a standard. A study group can move to working group status by meeting defined working group formation criteria.
Alderman said 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, he said, will proactively reach out to such groups to facilitate their early involvement. Individuals and companies that are interested in participating should contact Ray Alderman at firstname.lastname@example.org , with the subject line: VITA Architectures for Optical Study Group. He said VITA has set up a webpage at www.vita.com/voa to track information related optical technology. To learn more, go to www.vita.com.
