Common technical specification of the G-PON system among major worldwide access carriers

Gigabit-capable passive optical networks (G-PONs) have been successfully standardized at ITU-T following the work done by the Full-Service Access Network (FSAN) group. G-PON is a powerful and flexible optical access system with various options to accommodate many services and interface types. In order to provide guidance to vendors on the key options required by operators at this time and hence speed up early volumes for large field trials and deployments, many of the major worldwide access carriers (AT&T, BT, DT, FT, KT, NTT, and TI) have developed a common technical specification (CTS) for G-PON systems. This article describes the G-PON standard and underlines the scope and results of the CTS
