Returning to the Essence of High-Speed Copper Transmission with Precision Micro-Coaxial Architecture

Traditional USB cables rely on twisted-pair structures, which can suffer from severe crosstalk and signal attenuation at frequencies exceeding 20GHz. In contrast, the Elike USB4® 80Gbps Type-C® to Type-C® Coaxial Cable adopts an advanced coaxial design. Each conductor is built with a solid copper core, wrapped with high-grade PTFE (Teflon®) insulation, and enclosed within a 100% coverage shielding layer. This structure creates an almost perfect electromagnetic isolation environment, keeping signals stable while effectively blocking external interference.

Five Key Advantages of Advanced Coaxial Architecture

1. Durable and Flexible Outer Jacket

The entire cable features a high-strength TPE outer jacket, providing excellent flexibility and durability for commercial applications. The coaxial conductor structure further improves cable flexibility and handling performance.

2. Ultra-Low Signal Attenuation

By utilizing the excellent low dielectric properties of PTFE insulation, the cable supports stable 80Gbps high-speed transmission over extended distances. Each high-speed differential pair is individually shielded and surrounded by PTFE insulation.

With an extremely low dielectric constant (Dk ≈ 2.0), PTFE significantly reduces signal loss and transmission delay at high frequencies up to 20GHz. In this design, Teflon® is used only as an internal conductor insulation material to minimize dielectric loss, combined with 100% shielding protection.

3. Zero Electromagnetic Interference (EMI)

The fully shielded coaxial design ensures outstanding performance even in high electromagnetic noise environments such as server rooms, broadcasting studios, and industrial facilities.

4. Extremely Low Crosstalk

Each conductor features an independent shielding layer to eliminate interference between channels, ensuring ultra-low Bit Error Rate (BER) even under full-bandwidth operation.

5. Distance and Performance Balance

As a passive copper cable, transmission distance is limited by physical characteristics. For optimal 80Gbps performance, usage within 1.2 meters is recommended.
