The products are specially adapted to the requirements for data transmission with super vectoring. Even in G.fast applications with up to 1.5 Gbit / s, the 6 mm wide SPDs provide reliable protection, as confirmed by independent tests at Telekom in Germany. The integrated overload protection (power cross) also protects end devices in the event of faulty wiring. The one-piece protection devices TTC-6-1x2-TELE are available with both push-in and screw connection technology.
