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.
26 AWG balanced type
Balances frequency, diameter, mass, termination and airborne connector fit.
28 AWG lightweight type
For short high-speed box links on mass- and routing-constrained platforms.
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.

03 / TYPICAL CONSTRUCTION
From functional core to terminated interface
Silver-plated copper-alloy conductors
Gauge, voltage drop, strength and termination contacts define the conductor construction.
Low-loss insulation
Expanded PTFE/PTFE controls impedance, delay and high-frequency attenuation.
Controlled signal units
Differential pairs, quads or multichannel video/data units are formed around the protocol.
Individual and overall shields
Pair coupling, external EMI and connector return continuity are managed together.
Environmental jacket
Wide temperature, abrasion, flame, marking and harness termination are balanced.
