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. In this use, a PON has a point-to-multipoint topology in which an ISP uses a single device to serve many end-user sites using a system such as 10G-PON or GPON. In this one-to-many topology, a single fiber serving many sites branches into multiple fibers through a passive splitter, and those fibers can each serve multiple sites through further splitters. The light from the ISP is divided through the splitters to reach all the customer sites, and light from the customer sites is combined into the single fiber. Many fiber ISPs prefer this system.
ITU-T G.984 is the series of standards for implementing a gigabit-capable passive optical network (GPON). It is commonly used to implement the link to the customer of fibre-to-the-premises (FTTP) services.
Stewart David Personick is an American researcher in telecommunications and computer networking.

Anthony Michael Johnson is an American experimental physicist, a professor of physics, and a professor of computer science and electrical engineering at the University of Maryland, Baltimore County (UMBC). He is the director of the Center for Advanced Studies in Photonics Research (CASPR), also situated on campus at UMBC. Since his election to the 2002 term as president of the Optical Society, formerly the Optical Society of America, Johnson has the distinction of being the first and only African-American president to date. Johnson's research interests include the ultrafast photophysics and nonlinear optical properties of bulk, nanostructured, and quantum well semiconductor structures, ultrashort pulse propagation in fibers and high-speed lightwave systems. His research has helped to better understand processes that occur in ultrafast time frames of 1 quadrillionth of a second. Ultrashort pulses of light have been used to address technical and logistical challenges in medicine, telecommunications, homeland security, and have many other applications that enhance contemporary life.

10G-PON is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s over existing dark fiber. This is the ITU-T's next-generation standard following on from GPON or gigabit-capable PON. Optical fibre is shared by many subscribers in a network known as FTTx in a way that centralises most of the telecommunications equipment, often displacing copper phone lines that connect premises to the phone exchange. Passive optical network (PON) architecture has become a cost-effective way to meet performance demands in access networks, and sometimes also in large optical local networks for fibre-to-the-desk.

Higher Speed PON is a family of ITU-T recommendations for data links, capable of delivering shared Internet access rates up to 50 Gbit/s. Higher Speed PON is the first PON system to use digital signal processing, succeeding both single-channel XGS-PON and multi-channel NG-PON2. It provides upgrade paths for legacy PON generations such as GPON, XG-PON, XGS-PON, and 10G-EPON.
