Microconnect TB4020 Thunderbolt cable 2 m 40 Gbit/s Black

The Microconnect Thunderbolt Cable 2m (TB4020) is a 2‑meter, male‑to‑male Thunderbolt 4 cable that supports up to 40 Gbps data transfer and up to 100 W power delivery. It is built with an Intel Thunderbolt chipset and braided ultra-fine tinned copper conductors with TEFLON insulation and a flexible TPE jacket for reduced interference and improved durability. The cable is compatible with Thunderbolt 3 and 4 ports and many USB‑C devices that support the required features; note that regular Type‑C ports without Thunderbolt or DisplayPort Alt Mode are not fully compatible for all functions.

Advantages

This Thunderbolt 4 cable provides high bandwidth up to 40 Gbps for fast data transfer, supports dual 4K@60Hz or a single 8K@60Hz display when connected to a Thunderbolt port, and supplies up to 100 W of power delivery for rapid charging. The integrated Intel Thunderbolt chipset and quality materials ensure stable performance and reliability, while the flexible TPE jacket and TEFLON insulation increase longevity and reduce electromagnetic interference.

Suitable for

• Connecting external NVMe drives and high‑speed storage solutions
• Linking eGPU enclosures, docking stations and USB/Thunderbolt hubs
• Driving dual 4K displays or a single 8K display from a Thunderbolt port
• Powering laptops and devices that accept up to 100 W via USB‑C PD

How to use

Connect one end of the cable to a Thunderbolt 3 or 4 port on the host computer and the other end to a Thunderbolt‑capable device such as an external drive, docking station, eGPU or monitor. For maximum data and video performance (40 Gbps and dual 4K/8K output), both host and device must support Thunderbolt 4/3. When connecting to a USB‑C port that is not Thunderbolt, ensure the port supports DisplayPort Alternate Mode for video output; in that configuration the cable typically supports a single 4K display and reduced data bandwidth depending on the port specification.

Recommendations

To achieve full performance, use the cable with Thunderbolt‑capable ports on both devices and avoid using regular USB‑C ports that lack Thunderbolt or DisplayPort Alt Mode. Keep the cable free from sharp bends and excessive tension to preserve the TEFLON insulation and TPE jacket.
