High-Speed 16-Core USB Type-C Bulk Cable (4.8mm OD) for USB4, TBT4 & USB 3.2 Assembly

The 16-core USB Type-C bulk cable wire with a compact 4.8mm outer diameter (OD) is engineered for elite-tier, ultra-high-frequency data transmission. Unlike standard consumer-grade retail cables, this raw wire material is meticulously designed for custom cable assemblies, OEM manufacturing, and demanding B2B industrial ecosystems.

By utilizing advanced silver-plated copper micro-coaxial conductors, this bulk cable unlocks an exceptional physical bandwidth profile spanning from 10Gbps (USB 3.2 Gen 2) up to 40Gbps (USB4.0 / Thunderbolt 4.0). It delivers flawless signal integrity and low insertion loss for short-to-medium length applications without requiring active signal redrivers.

Key Technical Advantages of Our Raw USB-C Wire

  • Next-Gen High-Frequency Architecture: Optimized 16-core internal matrix capable of supporting USB 3.2 Gen 2, USB4, and Thunderbolt 4.0 terminations.
  • Ultra-Slim 4.8mm Profile: Maximizes flexibility and saves critical routing margins in tightly integrated embedded enclosures or medical device arms.
  • Premium Silver-Plated Copper Coaxial Pairs: Offers significantly lower attenuation, superior return loss, and precise 90Ω±10Ω differential impedance matching compared to cheap standard tinned copper.
  • Industrial & Medical Customization: Available with customizable TPE, TPU, or PVC jackets to withstand continuous flexing, chemical wipe-downs, or extreme environmental exposure.

Detailed Structural Specifications (Technical Breakdown)

To help your hardware engineers and processing technicians evaluate the cable anatomy, here is the exact internal core matrix layout:

  • 8 Coaxial Wires (30AWG): The high-speed core engine. Featuring silver-plated copper conductors paired with FEP insulation and a tinned copper wire outer shield. These lines guarantee strict $90\Omega \pm 10\Omega$ differential impedance control, eliminating jitter and signal degradation at 40Gbps.
  • 1 Unshielded Twisted Pair (UTP) (32AWG): Dedicated to legacy USB 2.0 (D+/D-) signalling, providing seamless backward compatibility while isolating cross-talk.
  • 4 Signal Wires (34AWG): Ultra-fine supplementary pathways optimized for critical control logic (such as CC and SBU lines) without stiffening the overall bend radius.
  • 2 Power Wires (24AWG): Heavy-gauge, low-resistance power conductors engineered to support high-current Power Delivery (PD) standards safely without voltage drops.
  • Heavy-Duty Braiding Shield: Wrapped in a high-coverage tinned copper braiding shield and premium aluminum foil to block electromagnetic interference (EMI) in harsh factory floors or medical rooms.

Frequently Asked Questions (FAQ )

Is this bulk cable truly compatible with USB4.0 and Thunderbolt 4.0 specifications?

Yes. Physically and structurally, the 16-core configuration aligns perfectly with the multi-channel layout required by advanced Type-C protocols. Thanks to the high-performance silver-plated copper coaxial structure and strict impedance matching, this raw wire provides the necessary attenuation margins for short-distance USB4 (20G/40G) and Thunderbolt 4 assemblies (dependent on final termination quality and E-Marker IC integration).

What jacket options are best for medical vs. industrial environments?

For medical devices, we highly recommend our Medical-Grade TPE, which offers bio-compatibility, a smooth matte texture, and high resistance to chemical disinfectants. For heavy industrial automation or robotic arms, our High-Flex TPU jacket provides superior mechanical abrasion and oil resistance.

Can the internal shielding structure or AWG wire sizes be customized?

Absolutely. As a dedicated OEM/ODM bulk cable manufacturer, we can fine-tune the braiding coverage, swap conductor materials, or adjust wire gauges (e.g., thicker power lines for higher PD wattage) to match your exact hardware specifications.

What is the Minimum Order Quantity (MOQ) for custom raw wire extrusion?

Production MOQs vary based on customization complexity and material selection. Please click “Request Sample” or contact our technical engineering desk to discuss low-volume prototype verification or large-scale contractual pricing.
