Abstract :
A comparison between different line codes suitable for transmission of 140 Mbit/s digital signals over 1.2/4.4 mm coaxial cable has been made using the computer optimization program, "OPUT." One alternative, the two level partial response class 1 (PR1), is chosen and a laboratory system has been built and tested. A block diagram of the system followed by a description is given. Performance of the system is presented and commented on. It is concluded that a PR1 system can be implemented with reasonable noise margin with a repeater spacing of 2.15 km for a 1.2/4.4 mm coaxial cable.
