Abstract

IEEE's 802.3ah (Ethernet in the First Mile task force) is concentrating on a standard aimed at making optical access affordable and ubiquitous. Subscribers will be able to get 1 Gb/s bi- directional capacity to the central offices. This Gigabit passive optical network (PON) system implies the use of low-cost opto-electronics and standard single-mode fibers. Historically, dispersion of single-mode fibers in these systems has not been an issue due to the relatively low data rates and limited distance. However, for optical Ethernet access, distances up to 20 km and extended temperature ranges are being considered. Therefore, there are now system limitations due to various dispersion penalties. This paper explores the fundamental issues of dispersion and its impact on the access network from a statistical point of view.
