Thunderbolt Optical Cable
2 Most Thunderbolt cables use copper wiring, but optical is also an option. The reason to use it instead is distance – versions of this cable range from 5.5m to 60m – but they’re expensive. You’ll need an inarguable reason to justify the cost, such as a super-fast connection for distributed video encoding, or to move loud equipment away during audio work. This cable has the speed you’d expect, but be warned that optical cables don’t carry power (just data), so make sure everything you connect has its own supply! Alan Stonebridge
Certainly expensive, but a justifiable cost when – and only when – there’s a clear professional need at hand.
