This document details the features and benefits of 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 — the lifeline of data transmission — are often run through very tight spaces in the spacecraft. For cables to reliably maintain signal integrity, they need to be flexible, and they need to be tough.
GORE Symmetrical Interconnects offer the best combination available for spacecraft component connections: solid mechanical durability, and excellent signal integrity. Small, lightweight and extremely flexible, these balanced, single-twinax cables deliver data transmission rates as high as 1 Gbit/s to maintain outstanding signal integrity.
The cables meet the stringent requirements of ESCC-3902/002, and are listed on the ESA QPL (Qualified Parts List) — providing the quality assurance critical to mission success in outer space.
The Science Behind the Cables
ePTFE in our cables helps to reduce interference between electrical systems.
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.
Features & Benefits
GORE Symmetrical Interconnects dependably feature:
- high signal speed up to 1 Gbit/s
- high density/reduced mass
- balanced, shielded lines
- high-speed link among units
By pairing these features with the material benefits of PTFE, our cables deliver:
- 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
Additionally, Gore’s worldwide engineering team provides sales and technical support. If you have any questions about GORE® Symmetrical Interconnects, please contact us.
Aboard spacecrafts, GORE Symmetrical Interconnects are typically used in:
- digital signal processors
- high-resolution cameras and sensors
- high-speed subsystem interconnects
To date, many critical missions have incorporated our symmetrical interconnects, including:
- European Remote Sensing Satellite (ERS1/ERS2)
- Polar Platform
- ENVISAT satellite
- XMM space observatory
- International Space Station (ISS)
All Gore symmetrical interconnects meet these technical specifications according to ESCC 3902/002 and are listed on the ESA QPL.
