22 AWG extended-distance type: Larger conductor section for power-drop and longer-link requirements.
24 AWG balanced type: Balances mass, diameter, termination and aerospace routing.
26 AWG lightweight type: For dense, short or mass-sensitive equipment links.
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.
Protocol and speed: Interface revision, target rate, encoding and maximum channel length
Electrical boundary: Impedance, insertion/return loss, skew and dielectric withstand
Channel construction: Pair count, auxiliary wires, power and shield zoning
Installation envelope: Gauge, diameter, mass, bend radius and harness section
Environment: Temperature, vibration, abrasion, fluids, smoke/toxicity and flame
Termination: Connector, contact, backshell, grounding and strain relief
