This article covers Cable Matters 40Gbps Thunderbolt 4ケーブル 2m.

Overview

The Cable Matters 40Gbps Thunderbolt 4 Cable 2m is an Intel-certified active cable that handles data, video, and power over a single USB-C connection. It offers up to 40 Gbps transfer speeds, 100W Power Delivery charging, and supports 8K display output. As one of the longest active Thunderbolt 4 cables on the market at 2 meters, it maintains signal integrity through built-in active electronics. This cable is fully backward compatible with Thunderbolt 3, USB4, and USB-C 3.2, making it a versatile choice for both current and older devices. Whether you're connecting a laptop to a dock, an external SSD, or a high-resolution monitor, this cable delivers reliable performance without compromise.

Connectivity & Compatibility

Both ends use standard USB-C connectors, so orientation doesn't matter. On a Thunderbolt 4 host, you get the full 40 Gbps throughput. It also works at 40 Gbps with Thunderbolt 3 and USB4 devices, and at lower speeds with USB-C 3.2/2.0 ports. DisplayPort Alt Mode is supported, enabling a single 8K @60Hz display or dual 4K @60Hz monitors. Power delivery goes up to 100W (20V/5A) for charging laptops, and up to 15W for bus-powered peripherals. The active circuitry ensures stable signal over the full 2m length, which is notably longer than many passive Thunderbolt 4 cables that top out at 0.8m.
