Microconnect TB4030 Microconnect TB4030

The MicroConnect TB4030 is a Thunderbolt 4 cable designed for high-speed data transfer, video output and power delivery. It uses an Intel Thunderbolt chipset and is built with coaxial conductors, fine tinned copper and TEFLON insulation inside a flexible TPE jacket to improve durability, reduce interference and provide consistent performance with Thunderbolt-enabled devices.

Advantages

The cable supports data transfer rates up to 40 Gbps when connected to a compatible Thunderbolt port and provides up to 100 W power delivery for fast charging. It can drive dual 4K@60 Hz displays or a single 8K@60 Hz monitor over a Thunderbolt connection, and is compatible with Thunderbolt 3/4 and USB-C devices that support the required modes. Built-in quality checks and a robust construction enhance reliability and longevity.

Suitable for

• High-speed data transfer between computers and peripherals (e.g., eGPU, external PCIe enclosures)
• Connecting docking stations, USB hubs and Ethernet adapters to Thunderbolt-equipped laptops
• Driving dual 4K@60 Hz displays or a single 8K@60 Hz display from a Thunderbolt port
• Charging laptops and devices that accept up to 100 W via USB-C Power Delivery

Key specifications

• Standard: Thunderbolt 4 (Intel chipset)
• Max data rate: up to 40 Gbps (when used with Thunderbolt ports)
• Power delivery: up to 100 W
• Video: Dual 4K@60 Hz or single 8K@60 Hz over Thunderbolt
• Construction: coaxial conductors, ultra-fine tinned copper, TEFLON insulation, TPE jacket
• Compatibility: Thunderbolt 3 & 4 devices and USB-C devices that support DisplayPort Alt Mode and required power/data modes (regular Type‑C ports without required modes are not compatible)
• Manufacturer: MicroConnect, MPN TB4030, EAN 5715063669518

How to use

Connect one end of the MicroConnect TB4030 cable to a Thunderbolt 4 (or compatible Thunderbolt 3) port on your computer and the other end to a Thunderbolt-enabled accessory such as a dock, eGPU, display or storage device. For video output from a USB-C port, ensure that the host port supports DisplayPort Alternate Mode; otherwise video output may be limited. To charge a laptop or device, plug into a port and confirm the device accepts up to 100 W via USB-C Power Delivery.

Recommendations

Use the cable with certified Thunderbolt ports to achieve full 40 Gbps performance and multi-display support. Avoid forcing connectors, route the cable to minimize sharp bends, and keep the cable and connectors clean to maintain reliable signal and charging performance.
