Overview

RELIABLE SOLUTION FROM A HERITAGE SUPPLIER

The NewSpace industry is evolving to help us better monitor the earth and connect us globally via mini satellites in orbit. Cables play an important role in transmitting high-speed data and keeping critical satellite systems running smoothly while meeting the latest protocols, like Ethernet. They must also be low-profile to help reduce mass in these smaller satellites and launch vehicles. Plus, these cables must be affordable and manufactured quickly to meet demanding program schedules.

At Gore, we combine extensive materials expertise with decades of proven traditional spaceflight heritage to offer a reliable, affordable high data rate solution with fast delivery for NewSpace applications.

EXCELLENT SIGNAL INTEGRITY IN A COMPACT DESIGN

GORE Ethernet Cables exceed Cat6a protocol requirements and are proven to deliver excellent signal integrity with sufficient margin for high-speed data transfer up to 10 Gb/s. Our unique 4-pair design performs reliably and consistently with lower signal attenuation, reduced crosstalk, and improved shielding effectiveness in digital video systems, telecommand remote systems, and more.

With a high-density construction, our Cat6a version is proven to endure the most demanding conditions commonly found in low earth orbit (LEO) and medium earth orbit (MEO) altitudes. For example, extreme temperature changes as the earth revolves around the sun, shock and vibration as vehicles are launched into space, and radiation exposure while satellites are in orbit.

But even though they’re high density, we design our cables with lightweight materials that make them significantly smaller in size — an ideal compact solution to help meet challenging mass budgets and tighter installation paths.
