TE Connectivity (TE) GDT (GDTs) placed in the sensitive telecommunications equipment (such as power lines, communication lines, signal lines and the data transmission line) before or in parallel, in order to prevent the transient voltage surge lightning and switching equipment operation caused damage to them. These devices will not affect the normal operation signal. However, if the voltage surge, such as lightning, GDT is converted to a low impedance state, and the energy transfer of sensitive equipment.

GDT provides advanced surge protection, a wide range of operating voltage, low capacitance and many shape factor, including surface mount devices, which makes it suitable for MDF (Main Distribution Frame) module, high data rate communication application of a class (such as: ADSL, VDSL) and provide for the transmission line surge protection. At the same time, low capacitance reduces signal distortion. The circuit protection programme coordination with PolySwitch equipment used, they can help manufacturers meet strict safety management standards.
