GORE® Space Cables, Type SpaceWire LITE

Constant High Data Rate Transfer

GORE^® Space Cables, Type SpaceWire, is proven to maintain constant bi-directional, high-speed data transmission up to 400 Mbps with minimal crosstalk, low insertion loss and low skew. They allow data to pass through the cable without significant signal loss using a serial, point-to-point dataline that supports LVDS.
