OWC offers high quality Thunderbolt cables in red/green/blue/black colors from 0.5 to 3.0 meters, as well as Thunderbolt optical cables from 10.0 to 30.0 meters in length.
Cable quality matters. Heck my kids keep breaking Apple Lightning cables with their iPhones (4 so far this year).
Here is what I am hearing about issues to consider with Thunderbolt cables:
- Having trouble with daisy-chained Thunderbolt devices or port expansion boxes like the OWC Thunderbolt 2 Dock? Replace the cable; it may solve the issue.
- Audio drop-out or noise from devices that have sound output through Thunderbolt? Could be noise/shielding. Swap the cable.
- Cables durability: breakage with lots of plugging/unplugging. Buy quality cables for a longer service life.
- Cables can have quality issues. If there is trouble with Thunderbolt devices, the first troubleshooting step is to swap out the cable(s) with high quality ones, preferably new.
- Note that the 2013 Mac Pro Thunderbolt ports are poor quality: the ports are sloppy (not a tight fit). Be sure to insert cables straight-on, with no torque/twist to the side.
MPG uses both Apple Thunderbolt cables and OWC Thunderbolt cables. Both are excellent: zero failures, zero problems, and MPG has a *lot* of stuff wired together with Thunderbolt.
The OWC offerings are very helpful because they can be had in four colors: with 6 of them coming out of the Mac Pro, and then some daisy chaining, it can be frustrating if all the cables are one color.
