Founded in 1995 by seven operators, FSAN is a telecommunications industry interest group that works towards a common goal of truly broadband fiber access networks. FSAN's mission is to encourage the incorporation of applicable standards, where they already exist, into industry services and products, while simultaneously advancing its own specifications in appropriate standard bodies to advance the further definition of the Full Service Access Network. FSAN has more than 70 vendor, operator and independent test lab members, which are now addressing interoperability of G-PON (Gigabit rate passive optical networking) and the seamless migration between generations of PON.
