A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. A PON takes advantage of (WDM), using one wavelength for downstream traffic and another for upstream traffic on a (ITU-T, typically OS2).

Each flavor of PON uses a different wavelength pair (one in upstream, one in downstream) to transmit data. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. 1310nm is commonly used for short to medium reach communication, such as within a building or a local area network.

Two major standard groups, the (IEEE) and the of the (ITU-T), develop standards along with a number of other industry organizations. Passive optical networking (PON), like active optical networking, uses fiber-optic cabling to provide Ethernet connectivity from a main data source to endpoints. Passive, in this context, refers to the unpowered condition of the fiber and splitting/combining. Passive Optical Networks Explained If you work with modern broadband or enterprise infrastructure, you've likely heard the term PON and wondered, "Exactly what is PON and why does it matter to me?" A passive optical network (PON) is a fiber‑based access network that uses unpowered optical. PON technology uses a point-to-multipoint architecture, utilizing a single optical fiber that branches out to.

Passive optical networks do not use electrically powered components to split the signal. Each splitter typically splits the signal from a single fiber into 16, 32, or up to 256 fibers, depending on the manufacturer, and several splitters can be aggregated in a single cabinet.

Unlike traditional GPON (Gigabit Passive Optical Network) solutions, XGS-PON delivers symmetrical speeds of up to 10 Gbps both upstream and downstream. This is the ITU-T 's next-generation standard following on from GPON or gigabit-capable PON. Characterized by its simple architecture, low equipment requirements, and energy. Cisco's family of 10-Gbps symmetrical passive optical network (XGS-PON) Optical Network Terminals (ONTs) delivers flexible, high-performance broadband connectivity for a wide range of fiber-to-the-premises use cases, including residential spaces, Multidwelling Units (MDUs), Small Office/Home Office.
