Microconnect TB4015 Thunderbolt Cable 1.5 m 40 Gbit/s Black

The Microconnect Thunderbolt Cable TB4015 is a 1.5 m, black Thunderbolt 4 cable that supports data transfer speeds up to 40 Gbit/s and delivers up to 100 W of power. It has male USB‑C connectors on both ends, is RoHS compliant and weighs 30 g. The cable uses an Intel Thunderbolt chipset and is designed for reliable, consistent performance with Thunderbolt‑enabled devices.

Advantages

This Thunderbolt 4 cable provides up to 40 Gbit/s data transfer when used with compatible Thunderbolt ports and supports dual 4K@60 Hz or a single 8K@60 Hz video output over a Thunderbolt connection. It supports 100 W power delivery for rapid charging and is constructed with coaxial wiring, ultra‑fine tinned copper conductors, TEFLON insulation and a flexible TPE jacket to reduce interference and increase durability. The cable is lightweight and easy to handle.

Suitable for

• Connecting Thunderbolt 3/4 docks, eGPU enclosures and external PCI‑E devices
• High‑speed data transfer between computers and storage devices
• Driving dual 4K@60 Hz displays or a single 8K@60 Hz display via Thunderbolt ports
• Charging laptops and devices that accept up to 100 W USB‑C power delivery

Key specifications

• Power delivery: up to 100 W
• Video: dual 4K@60 Hz or single 8K@60 Hz over Thunderbolt
• Connectors: USB‑C male — USB‑C male
• Cable length: 1.5 m
• Weight: 0.03 kg
• Colour: Black
• Compliance: RoHS

How to use

Insert each USB‑C male connector into the Thunderbolt ports of the host and target device. For full 40 Gbit/s performance and multi‑display video output, ensure both ends are connected to Thunderbolt‑capable ports. To output video from a USB‑C port, the host must support DisplayPort Alternate Mode (Alt Mode); in that configuration a USB‑C Alt Mode connection typically supports a single 4K display. Observe correct orientation when plugging in and avoid bending the cable sharply near the connectors.

Recommendations

Use the cable with devices and ports that explicitly support Thunderbolt 3 or 4 to achieve maximum performance. If connecting to a regular USB‑C port that does not support Thunderbolt, functionality and speeds will be limited; video output requires DisplayPort Alt Mode on the host. Store the cable without tight coils and avoid exposure to prolonged high temperatures to extend service life.
