Overview

Continuous improvements in avionics keep driving the demand to update aircraft with cables that can transmit lots of data at higher speeds so aircrews can receive real-time information. Cables must also be able to survive aircraft environments without breaking or failing, whether it’s constant flexing during routing or severe vibration during flight.

GORE FireWire Cables are the premier solution for copper-based IEEE 1394b FireWire data links. Our cables transmit uninterrupted high-fidelity signals for interconnect solutions up to 30 m (100 ft) at S400 data transfer rates in all aircraft environments

SIGNAL INTEGRITY WITH FLEXURE
Smaller-scale dimensions

Smaller-scale dimensions

We evaluated the eye pattern of our FireWire cables before and during flexure to ensure signal integrity. They passed the eye mask test with margin and continued to maintain signal integrity without degradation even after we wrapped them around a mandrel 20 times. Aircraft maintainers can easily flex and tightly bend our FireWire cables in narrow spaces during installation without damaging or breaking them.

Also, our specialized quadrax design is much smaller by about 40% and lighter weight than dual twisted pair constructions. Our FireWire cables can save as much as 5.2 kg (11.5 lb) per aircraft on average. But even though our cables are smaller and lighter, they still provide a protective barrier against tough aircraft environments because of the proprietary materials and double-braided shield that add strength.
