Other World Computing has introduced a fully certified 2-meter Thunderbolt 5 cable designed to deliver full bandwidth, display support, and power delivery at a longer distance.
The cable targets workstation layouts where high-performance peripherals are not positioned directly next to a Mac, such as under-desk mounts, shelves, or rack setups. OWC says the added reach allows more flexible desk arrangements without sacrificing Thunderbolt 5 capabilities.
Why cable length matters more with Thunderbolt 5
Thunderbolt 5 boosts baseline bandwidth to 80 Gb/s, with asymmetric allocation for up to 120 Gb/s for display traffic. Longer passive cables degrade signals, with cheap USB-C cables falling back to lower speeds.
OWC emphasizes certification as a differentiator. Thunderbolt-certified cables undergo testing to ensure consistent negotiated speeds, display behavior, and power delivery, which is crucial as bandwidth demands rise.
What this cable actually supports
OWC says the 2-meter cable supports full Thunderbolt 5 data speeds, high-bandwidth displays, and up to 240 watts of power delivery. Current Macs don't draw that much power over Thunderbolt, but the higher ceiling helps prevent negotiation issues with demanding docks and displays.
The added headroom also makes the cable suited for future systems and long-term workstation upgrades.
Display capabilities depend on the host system, but Thunderbolt 5's bandwidth allocation allows for more complex multi-display setups than previous generations. Final display counts and resolutions are still limited by the Mac's GPU and display engine.
Which Macs can actually use Thunderbolt 5 speeds
Thunderbolt 5 support is only available on Apple's latest high-end Macs. These Macs have M4 Pro or M4 Max processors, like recent MacBook Pro models.
Select Mac mini configurations also feature Thunderbolt 5 ports, offering higher bandwidth and expanded display capabilities.
Thunderbolt 5 increases baseline bandwidth to 80 Gb/s
However, Thunderbolt 5 is configuration-dependent. Base models using the standard M4 chip continue to ship with Thunderbolt 4, even within the same product line.
Older Apple silicon Macs with Thunderbolt 4 or Thunderbolt 3 ports can use Thunderbolt 5 cables. However, they will only operate at the host Mac's maximum supported speed.
The 2-meter Thunderbolt 5 cable is priced at $79.99, is available for preorder, and shipping is expected in early January.
