PURPOSE:To increase the ability of equalizing, by forming the ocean section equalizer with the power separation circuit, fixed equalizer and ocean section equalizer and constituting the variable equalizer with the equalizer units. CONSTITUTION:The transmission distortion expectable before the installation of submarine cables is corrected with the fixed equalizer 14 and the transmission distortion not expected taken place during the cable installation is corrected with the variable equalizer 11. The ocean section equalizer is constituted with the power separation circuit 13, fixed equalizer 14 and variable equalizer 11 and the equalizer 11 is constituted with the equalizer units 12, allowing to increase the ability of equalization without increasing the equalizing unit and working time. |
