Product Specifications

Key Features & Benefits

1. 5Gbps Speed Maintained Across 6ft

USB 3.0 operates at 2.5GHz. Cable length and construction affect signal integrity. This cable uses 90Ω differential impedance matching, low-loss HDPE insulation and dual-layer shielding.

In lab tests with a Samsung T5 SSD connected through this extension, sustained read/write exceeded 400MB/s, matching a direct connection.

2. 24AWG Power Conductors

Standard USB 3.0 cables often use 28AWG for power. This cable uses 24AWG for VBUS and ground. Voltage drop stays under 0.15V at 0.9A load. This supports stable power for external HDDs, portable SSD enclosures, VR headsets and gaming controllers.

3. Nickel-Plated Connectors

Nickel-plated brass connector shells resist corrosion from humidity, hand oils and atmospheric pollutants. Gold-flashed phosphor bronze contacts maintain low contact resistance (<30mΩ). In accelerated aging tests, connectors showed no measurable increase in contact resistance after 500 hours at 85°C / 85% RH.

4. Dual-Layer Shielding

The cable uses aluminium foil plus 64-braid tinned copper mesh. This attenuates EMI/RFI compared with unshielded or single-shielded cables. It supports stable data transfer when the cable runs near power bricks, monitor cables, Wi-Fi routers or Bluetooth dongles.

5. PVC Jacket and Strain Relief

PVC jacket with Shore A hardness 82

30mm overmoulded strain relief at both ends

10,000+ bend cycles at 180° with no signal degradation

6. Device Compatibility

Mass storage: external HDDs, SSDs, flash drives

Printers and scanners

Webcams and video conferencing

VR headsets: Oculus Rift, HTC Vive

Gaming peripherals: controllers, steering wheels, flight sticks

Audio interfaces and MIDI controllers

Docking stations and hubs

Data logging and test equipment

Digital signage and kiosks

7. Backward Compatible

The cable works with USB 2.0 devices at 480Mbps. When connected to USB 3.0 devices, it operates at 5Gbps.

Application Scenarios

Home Office Ergonomics Move external hard drives and printers away from the desk while keeping access.

Content Creation Workstations Position audio interfaces, MIDI controllers and capture devices where needed, not limited by rear ports.

Conference and Meeting Rooms Place USB webcams and conference microphones at suitable positions without moving the presentation PC.

Gaming Setups Extend VR headset cables to reduce tension. Connect controllers and wheels to front-facing ports.

Industrial and Lab Environments Place measurement instruments and data loggers at convenient locations while the host PC remains in position.

Retail and Digital Signage Extend touchscreen monitors and media players for front-panel access in kiosks and displays.

Live Events and Broadcast Provide extra reach for camera tethering, audio interfaces and capture devices.

Education and Training Labs Connect equipment to PCs without reaching behind monitor stands.

Technical Construction

Controlled Differential Impedance: 90Ω ± 5Ω Each production batch is verified with TDR to maintain a flat impedance profile across the 6ft length. Impedance spikes at connector junctions are reduced through soldering and moulding.

Low Attenuation Dielectric High-density polyethylene (HDPE) is used for the inner insulation of SuperSpeed data pairs. HDPE has a lower dissipation factor than PVC at 1GHz, reducing dielectric losses.

Skew Control Under 15ps The two conductors within each differential pair (SSTX+/- and SSRX+/-) are length-matched to within 0.3mm.

Shielding Continuity Dual-layer shielding is soldered directly to the connector shells at both ends, providing a low-impedance path to ground.

Power Line Sizing 24AWG VBUS and ground conductors provide approximately 0.04Ω per conductor over 6ft. This supports devices that draw burst currents during spin-up.

100% Automated Testing Each cable is tested for:

Continuity on all 9 pins

Short-circuit isolation

Hi-Pot insulation: 300V DC, >10MΩ

Attenuation @ 2.5GHz: <12dB/m

Characteristic impedance: 90Ω ± 5Ω

Real-device handshake with USB 3.0 host and device

Client Testimonials

VR Studio LA (USA) “We have 12 VR stations running daily. These 6ft extension cables give our headsets extra reach to reduce pulling tension on the ports. We haven’t had a cable-related port failure since switching to TLD’s extensions. We’ve ordered 100 more units.”

OfficeWorks Distribution (UK) “As a wholesale supplier of office peripherals, we include these extension cables in our printer and scanner bundles. Customers can position their equipment freely. The return rate is very low. TLD has become our supplier for connectivity products.”

MediaPro Studios (Australia) “We use these extensions in our live production rigs to connect audio interfaces and capture cards. We’re transferring high-resolution video at 5Gbps. TLD’s cables maintain speed and do not introduce errors. We now standardise on their USB 3.0 range.”

EduTech Solutions (Singapore) “We outfit school computer labs with these extension cables so teachers can connect demo devices without crawling under desks. The cables have survived two years of student use, better than the cheaper ones we used before.”

FAQ

Q1: Does adding an extension cable reduce USB 3.0 speed? A: No, if the extension cable is engineered for USB 3.0. With 90Ω impedance, dual-layer shielding and low-attenuation insulation, this 6ft extension maintains 5Gbps throughput. Up to two extensions (12ft total) can be daisy-chained without speed degradation. For runs beyond 15ft, active (powered) extension solutions are recommended.

Q2: Can I use this extension cable with a USB 3.0 hub or docking station? A: Yes. Place the hub or dock in a more accessible location while keeping the PC in position. The extension works with powered and unpowered hubs, provided total cable length from host to device stays within USB-IF recommended limits.

Q3: Will this extension cable charge my phone or tablet while transferring data? A: Yes. With 24AWG power conductors, the cable delivers 0.9A charging current with low voltage drop. For devices requiring more than 0.9A for fast charging, the cable delivers available bus power. The device’s own power adapter may be needed for maximum charging speed. Data and power pass simultaneously.

Q4: Can I get this cable in lengths other than 6ft? A: Yes. Custom lengths from 1ft to 15ft are available for bulk orders. Shorter lengths are used for desktop cable management. Longer lengths are used for conference rooms, studios or industrial setups.

Q5: What is the advantage of nickel-plated connectors? A: Nickel plating provides corrosion resistance and durability compared with bare brass. It withstands repeated plugging and unplugging, resists oxidation from humidity and hand oils, and maintains electrical contact over the cable lifespan. Gold plating is used for signal-critical applications; nickel offers a balance of durability and cost for extension cable applications.

Q6: Do you provide free samples? A: Yes. Free samples are available to qualified businesses. You only pay shipping. Contact the sales team to arrange a sample.

Q7: Is this cable compatible with USB 2.0 devices? A: Yes. It is backward compatible. USB 2.0 devices operate at 480Mbps through the extension. The cable does not limit speed; the device determines the speed.
