Overview

Increase Data Integrity Among Electrical Systems

Data integrity is key to maintaining communication among spacecraft systems during a mission. The cables that connect the systems have a direct impact on the quality of the data and the speed of transmission. GORE Space Cables and Assemblies, LVDS (Low Voltage Differential Signaling) Interconnects offer excellent signal integrity due to the combination of their robust design and their outstanding electrical performance, and are listed on the ESA QPL (Qualified Parts List).

These interconnects reduce time delay and skew of signal transmission, while consuming less power and minimizing electromagnetic interference. Their small size and minimum bending radius allow for easy installation in tight spaces. Their light weight decreases mass, thereby reducing the amount of energy needed to launch the vehicle into space. The high number of individual lines available in each bundle increases the cable’s flexibility and makes it easier to route the cable.

The Science Behind the Cables

The key to the outstanding performance of our LVDS Interconnects is the proprietary material used in the cable insulation — expanded polytetrafluoroethylene (ePTFE). This high-performance insulation provides excellent signal control for applications where tight impedance control is necessary. Expanded PTFE is both chemically inert and thermally stable, which allows these Interconnects to be used in tight spaces without compromising the strength and quality of signal transmission.

Features & Benefits

GORE Space Cables and Assemblies, LVDS Interconnects dependably feature:

  • tightest-available 100 ohm impedance of individual signal pairs
  • low signal attenuation and crosstalk
  • good EMC performance
  • Twinax design based on ESA 3902/002
  • multiple connector options
  • frequencies up to 3 Gbit/s range
  • vibration and shock resistance through QTP performance

By pairing these features with the material benefits of PTFE, our interconnects deliver:

  • excellent signal integrity, minimum noise, tight impedance control and outstanding EMC performance
  • high transmission speed from synchronously matched interfaces
  • outstanding clock synchronization between individual lines that distribute time-sensitive signals
  • easier installation resulting from small size and tighter bending radius
  • valued reliability delivered from an ESA-qualified and a DIN EN ISO 9001:2008-certified manufacturing facility

Additionally, Gore’s worldwide engineering team provides sales and technical support. If you have any questions about our LVDS Interconnects, please contact us.
