Key Features & Technological Innovations
Patented Dual Mono-Filament Technology
Each conductor is wrapped with two helical FEP strands before being enclosed in an extruded FEP outer jacket.
This creates a low-contact dielectric environment designed to minimize dielectric interaction and energy storage while supporting rapid signal propagation.
Four 20 AWG Silver-Plated Solid-Core OFC Conductors
Frey 2 USB-C employs 4 × 20 AWG solid-core conductors manufactured from 99.99999% high-purity OFC copper with pure silver plating.
The heavy-gauge solid-core construction provides consistent conductor geometry and robust current-carrying capability.
Controlled Twisted-Pair Geometry
The signal conductors use mechanically controlled spacing and twisted-pair geometry designed to maintain the electrical characteristics required for high-speed USB transmission.
100% Dual-Layer Shielding
A combined foil-and-braid structure provides 100% total coverage, helping isolate the USB signal path from:
- RF interference
- Electromagnetic interference
- External electrical noise
- High-frequency crosstalk
- Power-line noise within the cable assembly
Custom Gold-Plated Terminations
Frey 2 USB-C is available with custom gold-plated connectors in several configurations:
- USB Type-C → Type-C
- USB Type-C → Type-B
- USB Type-A → Type-C
This provides compatibility with both modern USB-C equipment and legacy USB-B DAC interfaces.
