ABSTRACT:
Transmission line sections in a connection comprise passive portions transmitting the signal without compensating for its natural attenuation and occupying 15% to 65% of the length of the section. They also include active portions that amplify the signal. The invention is particularly applicable to making intercontinental connections.
