Providing the triple play services of voice, video, and high-speed data access is an important way for carriers to increase their revenue and compete with other access providers such as the CATV operators. For both telephone network providers and CATV providers, the most flexible and future-proof medium for providing triple play services is fiber, with its virtually unlimited bandwidth availability. Since providing a direct optical connection between the CO and each subscriber is cost prohibitive, most optical access systems share a passive optical network (PON) among multiple subscribers. PON decreases the real estate of the CO, the labor cost involved in fiber access deployment, and length of fiber plant to maintain. This white paper provides some background on fiber-based broadband access technologies and a tutorial overview of the two most popular very high-speed PON access network standards: the ITU-T G.984 series Gigabit PON (GPON) and IEEE 802.3ah Ethernet PON (EPON) standards. GPON has been selected by most North America and European telephone network providers, while EPON is currently being mass deployed by some major Asian telephone network providers.
