Optical Links Boost Real-Time System Performance
By Rodger Hosking, Vice-president, Pentek, Inc.
Optical interfaces for gigabit serial links between real-time embedded system components offer significant advantages over traditional copper solutions. Performance benefits include improved data rates, increased transmission distances, reduced cable weight and diameter, immunity to EMI interference, and elimination of radiated emissions. Standardized mechanical and electrical implementations of optical transceivers, connectors, and cables defined in evolving VPX standards take advantage of emerging technologies and materials. Not only can these interfaces support legacy protocols like PCIe and Ethernet, they are also candidates for SerialFPDP and VITA 49 Radio Transport (VRT). These initiatives are boosting performance and opening up new applications in embedded systems for mil-aero applications including communications, radar, data acquisition, and software radio.
