High data rate cables step up Ethernet capacity in aerospace

June 02, 2015 // By Graham Prophet
W. L. Gore & Associates (Gore) has introduced Gore Ethernet Cables to meet the civil aerospace industry’s emerging need for higher data rate cables in a lightweight, flexible, and routable package.

Engineered for the demands of modern airborne digital networks, Gore Ethernet Cables provide high-speed data transmission up to 10 Gbit/sec over longer distances. They provide excellent signal integrity with stable performance in demanding environments, including a wide range of temperatures. These cables are available in two standard sizes – 24 AWG and 26 AWG.

The cables have a unique cable jacket material and high-density construction that significantly reduces weight and diameter for improved installation. This connector insert is a direct replacement for current quadrax technology that allows for up to 20 times the data in the same space. “Being able to directly replace a size 8 quadrax connector within an ARINC 600 or 38999 shell with the Gore 10GbE product combined with a Glenair, Inc. El Ochito [“ Little Eight ”] connector allows for a dramatic increase in data capability within the same form factor,” says Jeremy Moore, Application Engineer at Gore. The unique cable jacket material provides the combination of high speed and lighter weight necessary for a wide range of aerospace applications.

GORE 1394b FireWire cables have for some time been used for 1394b FireWire data links on military aircraft. Gore has developed this technology to deliver faster and more robust solutions to the civil industry and in-flight entertainment (IFE) market. Adrian Milne, Global Product Manager says, “Providing a capability within the IFE market place to replace multiple quad cables with a single 10GbE Gore cable allows our customers to save both weight and cost while increasing their ability to satisfy the industry demand for ever-increasing data usage.”

Typical applications for these Ethernet Cables include avionics networks, digital video systems, content loading, cabin management systems, flight management systems, Ethernet backbone, and IFE systems.

Higher data rate systems require greater attention to all electrical parameters, such as impedance control, attenuation, crosstalk, and EMI. Design engineers are integrating sophisticated electronics into almost every system of modern civil aircraft. It is
