Professional Extension Cable

This two-metre Thunderbolt 4 Type-C male to female extension cord delivers full 40Gbps bandwidth for professional content creators, eGPU builders and high-speed storage enthusiasts who need reliable signal integrity over distance. It supports 8K resolution at 60Hz video output and up to 240W power delivery for demanding workstations and docking hubs. Backward compatibility covers Thunderbolt 3, USB4 and USB 3.2, 3.1, 3.0 Type-C devices.

Build Quality and Connectors

The cable conforms to the Thunderbolt 4 specification, ensuring certified performance for data, video and power simultaneously. Male-to-female orientation lets you extend an existing Thunderbolt or USB-C link without adapters, preserving the original connector geometry on peripherals such as NVMe SSD enclosures, eGPU docks and capture cards. The 2-metre length provides routing flexibility inside chassis or across a desk while maintaining full electrical compliance.

Thermals and Power Draw

Passive copper construction means no active cooling, zero fan noise and no additional power draw beyond the connected devices themselves. The 240W PD capability handles sustained charging of high-performance laptops and workstations during heavy workloads without throttle events. Signal quality remains stable across the full length because the cable meets the Thunderbolt 4 electrical requirements for insertion loss and crosstalk.

Questions about this item

What bandwidth does the Thunderbolt 4 cable deliver in practice?

The cable delivers the full Thunderbolt 4 specification of 40Gbps bidirectional bandwidth, enabling lossless transfer of large 4K or 8K raw footage and NVMe SSD read-write tasks without bottlenecks.

What physical clearance does the 2-meter male-to-female extension need?

At 2 metres (6.6 ft) long, the cable requires enough free space between the host port and the peripheral to route the full length without sharp bends or tension on the connectors.

How is the cable installed, and which step do people often miss?

Plug the male end into the host Thunderbolt 4 or USB4 port and the female end into the device; the step users miss is confirming both ports support the required 40Gbps data, 8K@60Hz video and up to 240W PD so the full feature set is active.
