This paper presents details of dedicated cable television systems (stand‐alone cable TV), and combined cable TV/telephony systems, based upon the economic implementation of optical fibre technology. The factors that determine the choice of these two approaches are described and examples are given based upon systems designed by Raynet Corporation. Techno‐economic issues are debated and the need for effective future‐proofing is emphasized. In particular, the critical choice between fibre to the last amplifier (FTTLA) and fibre to the curb (FTTC) is discussed. Architectures are described for trunk and distributed systems and performance characteristics are given for a specific network, optical elements and electro‐optic interfaces. Detailed considerations relating to future developments conclude the paper.
