GPON: The Gateway PON
Fiber To The Home (FTTH) deployments continue to enjoy accelerated growth worldwide, with major deployments underway in Japan and the United States. Passive Optical Networking (PON) deployments are currently segmented in two flavors: Ethernet PON (EPON) and Broadband PON (BPON). In Europe and North America, Competitive Local Exchange Carriers (CLECs) are trialing and deploying PON very aggressively to provide services that differentiate them from the Incumbent Local Exchange Carriers (ILECs). Meanwhile, many local municipalities have started stringing their own fiber in their neighborhoods and inviting system vendors to enable end-to-end solutions.
This paper looks at current deployments, the applications driving them, and the factors that will determine the deployment toward a certain model. It also looks at the trends in the rest of the access market for clues to what may be in store for future FTTH deployments.
