When space missions demand reliable data transmission, GORE Space Cables for SpaceWire applications deliver — providing bidirectional, high-speed data transmission for satellites, telescopes observatories and other critical operations in spaceflight. Data transmission is essential to the success of every space mission. If data can’t be transmitted, the spacecraft could lose communication with mission control, leading to inefficiencies or even a failed mission. GORE Space Cables for SpaceWire applications ensure excellent, constant data transmission aboard various types of spacecrafts. Our cables provide bidirectional, high-speed data transmission up to 400 Mbit/s with minimal crosstalk, signal attenuation and low skew. Additionally, the cables meet the stringent electrical and mechanical requirements of ESCC 3902/003. Using a serial, point-to-point dataline with Low Voltage Differential Signaling (LVDS), our space cables for SpaceWire applications reduce costs because they can be integrated into many different satellite programs without the need for custom designs. Among the cables’ applications are high-resolution cameras and radar sensor equipment, and they are used aboard the James Webb Space Telescope and the Sun Dynamics Observatory. Cables are available in either bulk or custom-assembled forms, terminated on micro-miniature D-type connectors. The key to the performance of GORE Space Cables for SpaceWire applications is the proprietary material used in the cable insulation, expanded polytetrafluoroethylene (ePTFE). Using ePTFE, we support LVDS, which allows data to pass through the cable without significant signal loss.
