Abstract

PURPOSE:To remarkably simplify the cable installation work, to reduce the level margin and to economize by the equalization of unexpected level mismatching and that produced after the installation with variable equalizing circuit possible for remote control. CONSTITUTION:The variable equalizing circuit 41 which can be remote controlled from the land station is provided. The relay unit 3 is inserted to the coaxial cable being the transmission media with a suitable distance, solid state equalizer 3 is located every relay unit determined, and the ocean equalizer 4 (consisting of the circuit 41 and fixed equalizing circuit 42) every multiple of the insertion distance of the equalizer 3. The equalizer 3 and the circuit 42 are factory assembled in the factory in advance to equalize the level mismatching expected before installation, and the circuit 41 is the equalizing circuit to equalize the level mismatching observed during installation which is not expected before the installation and that produced at the system construction with remote control.
