Annotation: The article is devoted to one of the most popular and promising means of broadband communication - a technology called “Passive optical network” or PON for short. The article also discusses the architecture of access networks, classification, features and issues of passive optical network technology backup. A passive optical network is a fiber-optic network utilizing a point-to-multipoint topology and optical splitters to deliver data from a single transmission point to multiple user endpoints. Passive, in this context, refers to the unpowered condition of the fiber and splitting/combining components. The PON upstream distribution network, based on a fiber optic cable architecture similar to a passive optical splitting tree at nodes, is the most cost effective and can provide broadband transmission for a variety of applications. At the same time, the PON architecture has the necessary efficiency to increase both network nodes and bandwidth, depending on the current and future needs of subscribers.

Keywords: Passive optical network, broadband, wireline communication, access technologies, optical distribution network, high sensitivity, infrastructure, receiver module, external influences.
