This article covers StarTech.com Thunderbolt 4ケーブル.

The StarTech.com Thunderbolt 4 Cable (model TBLT4MM50CM) is a premium 50cm USB-C cable that delivers 40Gbps data transfer and up to 100W USB Power Delivery.

It's Intel certified for Thunderbolt 4, ensuring rock-solid compatibility with Thunderbolt 4 and 3 hosts, as well as USB4, USB 3.2 Gen 2, and DisplayPort Alt Mode devices.

With DSC-enabled DisplayPort 1.4a support, it can drive a single 8K60Hz display or dual 4K60Hz monitors.

This cable is designed for users who need a single, reliable connection that handles high-speed storage, high-resolution video, and laptop charging all at once. The 50cm length is ideal for keeping desk setups tidy by minimizing cable slack between a laptop and its dock or monitor.

Connectors: USB-C male to USB-C male. The cable supports Thunderbolt 4 (40Gbps), Thunderbolt 3 (40Gbps), USB4 (40Gbps), USB 3.2 Gen 2 (10Gbps), and DisplayPort Alt Mode with DSC.

It works with any Thunderbolt 4 laptop, iPad Pro (5th gen and later), Thunderbolt docks, 4K/8K monitors, PCIe external enclosures, and Thunderbolt networking gear. Full 40Gbps performance requires a Thunderbolt 4 port on both ends.

When connected to a standard USB-C port (e.g., on a non-Thunderbolt PC), the cable operates at USB 3.2 Gen 2 speeds (10Gbps).

Backward compatible with Thunderbolt 3, so older Thunderbolt 3 laptops still get full 40Gbps throughput. Released in late 2023, the TBLT4MM50CM sits in the high-end cable segment.

It offers Intel certification, 40Gbps throughput, 100W PD, and DSC video support—features that clearly exceed typical USB-C cables. The build quality includes nickel-plated connectors with PVC strain relief, a coaxial alloy braided shield for EMI protection, and a halogen-free TPE jacket.

Warranty is 2 years standard (extendable with registration). No accessories included—just the cable itself.Check the retailer's page for the latest price.

It's available through Japan, StarTech's own online store, and select electronics retailers. Ideal for Thunderbolt 4 laptop owners (MacBook Pro, Dell XPS, ThinkPad X1 Carbon, etc.) who need a reliable single-cable connection to a dock or monitor that handles data, video, and charging.

Creative professionals working with 8K video or multi-4K setups will appreciate the DSC-enabled DisplayPort Alt Mode support. Also perfect for desktop cable management.

The 50cm length works beautifully when your laptop sits close to its dock or hub—no coils, no tangles. If you need longer runs, consider StarTech's 100cm or 200cm Thunderbolt 4 cable variants.
