> 3m is beyond the max cable length specified by Thunderbolt, so it requires active extenders (they're hidden in the plugs) and tight manufacturing and shielding.
The ICs at both ends, tight manufacturing, and shielding are required even for a 0.5m Thunderbolt cable.
For a 3m cable, the manufacturing tolerances and shielding go up even higher, but they were still required even for short cables.
