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
TThe 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.
