It is regarded by most operators as an ideal technology to realize broadband and comprehensive transformation of access network services. GPON was first proposed by FSAN organization, and ITU-T completed ITU-TG on this basis in March 2003 The formulation of g.984.1 and g.984.2, and the standardization of G.984.3 was completed in February and June 2004.
