Abstract: This article describes information network - a backbone network structure, a video switch topology and acousto- optics processor applications - AOP. Cable is a natural network for carrying high-capacity, bandwidth - in tensity information. In the age of analog program signals, cable capacity was a natural transmission media for broadcasting of color TV and high-fidelity stereo sound programs.
