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.
G.987: 10-Gigabit-capable passive optical network (XG-PON) systems: Definitions, Abbreviations, and Acronyms, 2010. G.987.1: General requirements of 10G-PON systems (approved 2010-01-13). Includes examples of services, user network interfaces (UNIs) and service node interfaces (SNIs), as well as the principal deployment configurations that are ...
It is commonly used to implement the link to the customer (the last kilometre, or last mile) of fibre-to-the-premises services. [ 2 ] [ 3 ] GPON puts requirements on the optical medium and the hardware used to access it, and defines the manner in which Ethernet frames are converted to an optical signal, as well as the parameters of that signal.
Following the publication of 40 Gbps NG-PON2 in July 2015, standardization activities turned to higher speed PON. [4] In November 2016, the Full Service Access Network (FSAN) Group released the Standards Roadmap 2.0 which indicated the development of "future optical access systems" with peak transmission rates above 10 Gbps.
NG-PON2 (also known as TWDM-PON), Next-Generation Passive Optical Network 2 is a 2015 telecommunications network standard for a passive optical network (PON). The standard was developed by ITU and details an architecture capable of total network throughput of 40 Gbit/s, corresponding to up to 10 Gbit/s symmetric upstream/downstream speeds available at each subscriber.

A passive optical distribution network (PON) uses single-mode optical fiber in the outside plant, optical splitters and optical distribution frames, duplexed so that both upstream and downstream signals share the same fiber on separate wavelengths. Faster PON standards generally support a higher split ratio of users per PON, but may also use ...
In 2021, Adtran entered into a business combination with ADVA Optical Networking SE, a cloud and mobile services networking company based in Munich and Meiningen in Germany. [11] In 2022, Adtran acquired the remaining shares of Cambridge Communication Systems (CCS) Limited, a developer of wireless backhaul and transport systems for small cells.
