I think all Thunderbolt cables are actually active, it’s just the chips at each end are pretty tiny so for a lot of cables you wouldn’t know it’s hiding inside the connector.

They require a marker chip, but that's pretty different from being an active cable. Pennies vs. dollars.

Passive ones are available in multiple lengths up to 2 meters, but only go half speed above .5 meters.
