Aerospace and military designers are demanding higher data rates in lighter packages, so engineers at W.L. Gore & Associates, Inc., developed the GORE Ethernet cables. They use the cable jacket material found in GORE 1394b FireWire and are designed modern airborne digital networks. Higher data rate systems require greater attention to all electrical parameters, such as impedance control, attenuation, crosstalk, and EMI. This CAT-6A cable supports TIA-568 applications as fast as 10 gigabits while increasing signal density with reduced cable diameter. The products are available in two standard sizes – 24 AWG and 26 AWG. These cables meet the performance requirements of ANSI/NEMA WC 27500 Standard for Aerospace and Industrial Electrical Cable, Type 24.

The Ethernet cables reduce weight while maintaining reliable signal integrity. Jacket weight is reduced by as much as 37 percent when compared to ethylene tetrafluoroethylene (ETFE) materials and 50 percent when compared to fluorinated ethylene propylene (FEP). GORE cables such as the 1394b FireWire cables have been used for data links on Lockheed Martin’s F-35 program to enable data transfer while reducing platform weight. Typical applications for GORE Ethernet cables include: avionics networks, digital video systems, cabin management systems, flight management systems, Ethernet backbone, and in-flight entertainment systems.
