Passive Optical Networks (PONs) have generated considerable interest for telephony applications, and this architecture has been claimed to be very suitable for distribution of video signals as well. The term PON covers an array of design variations (e.g. two fiber versus one fiber), and several trial networks have been built using different designs. This paper describes a number of current approaches to PON design, and typical parameters are given. The characteristics of a typical PON video delivery system are described in terms that allow network operators to evaluate the applicability of this technology to their networks.
