Application:
The product series adopts a multi-stage protection architecture. The front stage utilizes gas discharge tubes (GDTs) to withstand high lightning current impulses, while the rear stage employs low-capacitance TVS diodes for fast response speed. It provides protection for 1-pair and 2-pair lines, effectively safeguarding communication signal equipment from transient overvoltage interference and damage.
