Cable Performance and Specifications

Balancing a high-temperature acrylate coating with a rugged buffering system, GORE Fiber Optic Cables (1.8 mm Simplex) for Defense Aircraft offer an impressive level of robustness to protect the fiber core. Their construction includes:

  • Perfluoroalkoxy (PFA) jacket with JN1177 marking
  • Strength member
  • Secondary expanded polytetrafluoroethylene (ePTFE) layer
  • Crush-resistant layer
  • Primary ePTFE layer

This version also features a slender design with smaller diameters and lighter weight materials for maximum flexibility and tight bending than competitive cables built with a double jacket. Available in single or multi-mode core types, our 1.8 mm Simplex accommodates current and next-generation avionics digital networks operating at 10 Gb+ up to 100 Gb/s.


To demonstrate higher weight impact resistance, GORE Fiber Optic Cables (1.8 mm Simplex) for Defense Aircraft were tested using EN3475, method 506. After repeating the test 5 times in the same spot with a crushing force of 800 grams (1.8 pounds), results revealed that our cable retained its optical properties with low attenuation, meeting minimum requirements for added durability.

Because electronic systems can be exposed to hot and cold conditions during flight, we tested our 1.8 mm Simplex for vibration and shock performance in extreme temperatures. Results showed no degradation or optical loss in temperatures ranging from -40°C at 850 nm to +135°C at 1300 nm, proving superior strength against high-intensity vibration and mechanical shock for a longer lifespan.


Since cables can easily get damaged during routing in narrow aircraft pathways, we tested the electrical stability of our fiber optic cable using EN3745, method 514. Results indicated that our 1.8 mm Simplex maintained reliable signal integrity after twisting and bending for 2,000 cycles with no evidence of jacket degradation, softening, surface damage, cracking, splitting or penetration for easier, more reliable installation.


We also examined our fiber optic cable’s ability to resist severe kinking and over-bending using EN3745, method 509. Results revealed that our high speed cables maintained stable optical performance with low loss without kinking or breaking, exceeding the minimum requirements.

To better support maintainers when terminating connectors with cables, we tested our cable’s shrink-back resistance according to EN3745-205, method A. Results verified that our 1.8 mm Simplex met the qualification with dimensional stability and low jacket shrinkage after 25 cycles in temperatures ranging from -65°C to +135°C without thermal pre-conditioning.

Meeting Rigorous Standards across Aircraft Applications

Aviation cables must resist routine maintenance activities and extreme airborne environments while meeting size, weight and routing constraints. The 1.8 mm Simplex of GORE Fiber Optic Cables is tested and pre-qualified to make sure they meet or exceed the most rigorous standards for high data rate cables in defense aircraft, like the Eurofighter. These standards include:

  • ABD0031 (AITM 2.0005); BSS7230; FAR Part 25, Appendix F, Part I: Flammability
  • ABD0031 (AITM 3.0008B); BSS7238; FAR Part 25, Appendix F, Part V: Smoke Density
  • ARINC 802-3; Performance Requirements (GSC-13-84639, GSC-13-84640, GSC-13-84943)
  • BSS7239: Toxicity
  • EN3745-513; JN1177: Test Methods for Crush Resistance (GSC-13-84943-07)
