You didnt need the corning one, though, that's an electrically isolated cable, maybe thunderbolt can't go far unless it is media translated to optical, but I am unsure.
10+ gigabit serial connections (Thunderbolt, USB 3.2/4 DisplayPort 1.4, HDMI 2.1, etc) are limited to 1 or 2 meters on passive copper cables. You need optical for anything longer (or a hot, power-hungry transceiver, like for 10GBaseT ethernet)
