DSL-FLÜ serve the transmission and electrical surge coarse of DSL modems. Through the use of – specially adapted to the requirements of DSL transport – transformers, electrical isolation of the modems is ensured by the copper line which provides reliable protection to 6 kV.

Via a curse overvoltage protection the DSL-FLÜ can be discharged to earth. The modem such as the transmission side can optionally be connected via RJ-45 or screw connectors.
