The Case for EPON: Performance in Cell Backhaul Operations.

The article focuses on the application of the Ethernet passive optical network (EPON) in the cable television and telecommunications sector in the U.S. EPON is economically and technically superior to SONET rings for cell backhaul operations. Though 2.5G/3G backhaul can benefit from EPON savings, EPON efficiencies will be required for 4G networks' data rates and increased cell tower density. EPON tree architecture is the best network architecture for the high density of calls that are required for 4G telecommunication technologies.
