吉比特无源光网络GPON技术及其标准化(Gigabit passive optical network GPON technology and its standardization) Is described in this paper, the main technical features of GPON, and further explained in detail the function of protocol layer, the DBA mechanism, the ONU activate registration, OMCI, such as key technology and principle, also introduces the GPON carrying two specific ways a TDM business, as well as the standardization of GPON technology. The proposal of GPON technology GPON (gigabit-capable Passive Optical Network, Gigabit Passive Optical Network) technology is an important technical branch of the non-source Optical Network (PON) family, and other similar technologies include APON/BPON and EPON technology. GPON is one of the most closely watched optical access technologies in the current and future 2 to 3 years. Concept of GPON, as by FSAN (Full Service Access Network, the whole business Access Network) is put forward in 2001, before this, FSAN/ITU also proposes and standardize the APON, BPON technology (ITU - T G. 983. X series standard), IEEE has also started to EPON technology standardization and soon officially released in 2003 IEEE 802.3 ah, marking the EPON technology standardization work completed. FSAN/ITU launched the biggest reason is due to network IP GPON technology progress of acceleration and ATM technology based on ATM technique is gradually shrinking before APON/severely hindered BPON technology in commercial and practical aspects, urgently need a high transfer rate and optimum IP bearer at the same time with integrated service access ability of optical access technology. In this context, the FSAN/ITU is based on the APON standard as the basic framework, redesigning the new physical layer transmission rate and TC layer, and introducing new GPON technology and standards. The composition of GPON system And other similar PON technology, GPON is also a kind of the point to multipoint topology of passive Optical access technology, by the side of the bureau of OL
