All Resources For GORE® Aerospace FireWire® Cables, 1394b for Military Aircraft


Continuous improvements in aerospace technology keep driving the demand to update military aircraft with cables that can transmit lots of data at higher speeds. Cables also need to deliver more power and reliable signal integrity in less space.

GORE Aerospace FireWire Cables are the premier solution for copper-based 1394b FireWire data links. Our cables provide high-fidelity signal links for interconnect solutions up to 75 feet at S400 data rates for uninterrupted high-speed communication on modern avionics networks.

Smaller Quad Cable Diameter

Smaller, Lighter Cable Design

We evaluated the eye pattern of our 1394b FireWire cables before and during flexure to ensure signal integrity. Results showed that they passed the eye mask test with margin, indicating greater transmission length is possible. Our highly flexible cables continued to maintain signal integrity even after we wrapped them around a mandrel 20 times. So, aircraft maintainers can easily and tightly bend our cables in narrow spaces during routing without damaging or breaking them.

Also, our specialized quad design is significantly smaller by approximately 40% and lighter weight when compared to conventional constructions such as dual twisted pair cables. So, our 1394b FireWire cables can save as much as 11.5 lbs. (5.2 kg) per aircraft on average. But, even though they’re smaller and lighter, our cables boost performance and protection in challenging military environments because of the added strength in their construction.
