01 / CONFIGURATION DIRECTIONS
Select a configuration from the application boundaries
These configurations establish a practical discussion starting point. The final product requires a controlled specification based on interface, length, installation and validation conditions.
Cat 6A four-pair
For avionics backbones, vision and mission networks up to 10 Gb/s, balancing transmission performance, diameter and mass.
Cat 5e two-pair
For two-pair protocols and space-constrained equipment links, reducing conductor count, diameter and mass while supporting frequency directions up to 1 GHz.
Cat 5e Quadrax
A 100-ohm symmetrical quad for aerospace connector systems; indicative link directions are 70 m for 24 AWG and 50 m for 26 AWG.
Match a solution direction to the link target
Solution codes support early technical discussions by aligning protocol, construction, link boundaries and application in one view.
