ABSTRACT:
A bilateral transmission system for bilateral signal transmission through a two-way transmission line, in which a plurality of first bilateral transmission circuits and a plurality of second bilateral transmission circuits are alternately inserted in the two-way transmission line at substantially regular intervals. The first bilateral transmission circuit is formed by a first amplifier for transmitting the signal in the forward direction, a first by-pass line for transmitting the signal in the reverse direction and at least one first hybrid circuit for connecting the first amplifier and the first by-pass line to the two-way transmission line. The second bilateral transmission circuit is formed by a second amplifier for transmitting the signal in the reverse direction, a second by-pass line for transmitting the signal in the forward direction and at least one second hybrid circuit for connecting the second amplifier and the second by-pass line to the two-way transmission line.
