The coupling devices, in conjunction with coupling capacitors, allow the transmission of carrier frequency signals and, at the same time, offer an efficient protection against the effects of the power frequency voltage and transient overvoltages for personnel and PLC equipment. Key Features: - Designed according to IEC 481 standard - Frequency range of 40 to 500 kHz - Nominal P.E.P of 400 W - Nominal equipment side impedance of 75 and 125 Ω (other values on demand) - Special models for underground cables - Nominal line impedance of 100 to 750 Ω for phase-to-earth coupling - Distortion and intermodulation lower than 80 dB below the nominal P.E.P. - Return loss higher than 12 dB - Composite loss lower than 2 dB - Operates with coupling capacitors of 2 nF (or higher)   Information           High Performance Optical Communications:   Optical Amplifier   Select a product SPX-OA   Core DWDM Node   Select a product SPX-96   Metro CWDM/DWDM Node   Select a product SPX-64 SPX-64+   Access Node   Select a product SPX-04   Fault Circuit indicator system:   Underground MV networks   Select a product DPF   Power-line Carrier systems   Universal Terminal   Select a product OPU-1   Power-Line Carrier systems:   Analog Terminal   Select a product OPC-1 OPC-2 OPL-1   Digital Terminal   Select a product OPD-1 OPD-2+   Teleprotection systems:   Analog Terminal   Select a product TPC-2   Digital Terminal   Select a product TPD-2   Universal Terminal   Select a product TPU-1   High-Frequency Terminal   Select a product
