Synchronous Digital Fiber Optic Networks for Multi-Channel Video Transmission

New terminology is appearing in today's television system planning such as multi-media, video compression and communications “super-highways”. The underlying structure of these concepts is digital technology and digital transmission. In modern communications structures, fiber optics is the dominant medium for terrestrial transmission of digital signals, and digital fiber optic systems are becoming well established for transporting high quality video, audio and data signals. — Digital coding enables a very robust transport medium and has other practical system advantages. A multi-level, synchronous, time division multiplex (TDM) architecture is the key element in realizing the flexible, high performance advantages of digital transmission. The ability of a digital system to interface with multiple signal formats and the emerging telecommunications optical network standards is another important advantage. Considerations for a synchronous TDM, including an advanced design for distributing clock signals will be covered as well as signal interfacing aspects of a digital system.
