PASSIVE OPTICAL NETWORKING UPDATE E-PON

Gigabit passive optical network (GPON), and broadband PON which preceded it, were produced from the Full Service Access Network (FSAN) group and the International Telecommunication Union — Telecommunication Standardization Sector (ITU-T) standards organization. As it was originally framed in 2002, G-PON was designed to be an inclusive standard, covering the carriage of time-division multiplexing (TDM), data, and video services, using both asynchronous transfer mode (ATM) and packet payloads, at a wide variety of speeds and loss budgets. This wide-scope strategy helped promote quick adoption of G-PON, since it could accommodate pretty much any service and fit into a wide range of network situations. Today, G-PON is a mature fiber access transmission system. As time has passed, G-PON contin
