STG 2000 Single Pair Protection plugs (SPP) SOR PU are designed for use with STG 2000 modules to provide protection to individual copper pairs of most voice and data, fixed and wireless network applications, against high voltage surge due to lightning and overcurrent, generated by induction or direct contact with power lines.
The SPP´s increase flexibility in network management. They can be removed separately for replacement on faulty lines alone without disturbing adjacent working lines.
