These splitters fit into standard splice enclosures
and can be conveniently installed with the cable, providing little maintenance, if any.
Environmentally controlled vaults (CEVs), required in DSL and other copper technology
deployments are thus eliminated, thus no air conditioning systems, large pedestals,
commercial powering, backup power systems as well as time-consuming technician
dispatches are required.
EPON networks also employ bidirectional communications over a single fiber cable,
thus reducing the amount of required fiber deployment by approximately 50 percent
and providing a more cost-effective fiber structure for the network operator. In case of
service providers with exhausted fiber capacity, EPON systems enable the reclamation
of capacity through better fiber utilization, allowing for service provision for greater
numbers of subscribers. A single fiber strand can, therefore, provide connectivity to as
many as 16/32 customers at a distance of up to 20 km, in accordance with the IEEE
802.3ah standard. The smaller the network diameter, the greater the number of customers,
thus typical upgrades from P2P Ethernet links to EPON systems result in a
fiber structure capable of supporting more than 32 customers at a time.
