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.
