A lot of work is, therefore, required to provide
viable and simultaneously efficient means for assuring subscriber data privacy and authentication,
as well as antimonitoring measures, preventing any attempts at passive
data-mining techniques, which typically constitute the first step in launching a more
destructive attack on the EPON system.
Economic Assessment
Because of the wide variation in service requirements, costs, regulation, and degrees
of modernization among service provider networks worldwide, it is not possible to construct
a simple business case for EPON that would hold in all or perhaps even most
instances. Instead, in this section, we will highlight some of the fundamental nontechnical
issues surrounding a real EPON deployment. While it is safe to assume that a
real business case would include most of these issues, we cannot predict how any one
service provider might weigh the various factors.
Overall Installation Cost per Subscriber
A detailed cost model for an EPON deployment will include costs for central office equipment,
fiber cable, splitters, supporting infrastructure (conduit and utility poles), construction
costs at the subscriber??™s location, and customer premise equipment (CPE) costs.
