Abstract :
This paper deals with an experimental 139.264 Mbits/s digital transmission system on 1.2/4.4-mm coaxial cable at present under field trial. The system utilizes the hybrid transmission technique in which many analog repeaters axe placed between two regenerators. A detailed equipment description is reported and the results of the field trial on an experimental link are given.
