GORE® Space Cables and Assemblies: Symmetrical Interconnects Data Sheet - 1

GORE Space Cables and Assemblies ® Symmetrical Interconnects Improve Signal Transmission for Spacecraft Electronics Signal speed and integrity are essential for effective communication among spacecraft components. Cables are the lifeline of data transmission and are often run through very tight spaces in the spacecraft. Meeting the stringent requirements of ESCC-3902/002, GORE® Symmetrical Interconnects are small, lightweight, and extremely flexible. These balanced, single-twinax cables maintain outstanding signal integrity at data transmission rates as high as 1 Gbit/s. GORE® Symmetrical Interconnects offer the best combination available for spacecraft component connections — solid mechanical durability and excellent signal integrity. The Science Behind the Cables The key to the outstanding performance of GORE® Symmetrical Interconnects is the proprietary material used in the cable insulation — expanded polytetrafluoroethylene (ePTFE). By incorporating ePTFE into the cables, Gore is able to provide tight impedance control to reduce interference, with balanced transmission between separate lines within the cable. The microstructure of the ePTFE material makes GORE® Symmetrical Interconnects lighter than other cables with comparable performance and minimizes the problems associated with balancing difficult mass budgets. Typical Uses •• Digital signal processors •• High-resolution cameras and sensors •• High-speed subsystem interconnects Sample Applications •• European Remote Sensing Satellite (ERS1/ERS2) •• Polar Platform •• ENVISAT •• XMM •• International Space Station (ISS) International Space Station •• INMARSAT Image: ESA Realize the Benefits of GORE® Symmetrical Interconnects Key Features •• High signal speed up to 1 Gbit/s •• High density/reduced mass •• Balanced, shielded lines •• High-speed link among units Key Benefits •• Excellent compatibility among system components •• Reduced costs for system integration and maintenance •• Design flexibility of a modular system •• Improved reliability from rugged materials used in construction •• Valued reliability delivered from an ESA-qualified and a DIN EN ISO 9001:2000-certified manufacturing facility •• Superior sales and technical support from Gore’s worldwide engineering team
