However, nearly 90 percent of business locations are not currently served by fiber,
and even fewer residential subscribers have optical access. Although technologies such as
optical Ethernet or Passive Optical Networks (PONs) offer maximum bandwidth potential,
they require very expensive fiber builds. Using Mid-Band Ethernet allows providers to
offer high-bandwidth services without deploying fiber all the way to the premise.
In some cases, the Mid-Band Ethernet copper access technologies are funding fiber
build-outs. Because Mid-Band Ethernet has such a fast return on investment and can
generate significant revenue very quickly, carriers can use it to pay for the fiber build.
Suppose a couple of enterprise customers come online today with a 10 Mbps Ethernet
service for $1000/month from the same business park. After a year or two, the carrier may
very well have collected enough revenue to pay for a fiber drop to that business park.

So Mid-Band Ethernet is ideal for today??™s conservative, practical economic climate.
It leverages the existing copper infrastructure and low-cost unbundled network loops
to deliver high-bandwidth Ethernet services complementary to the optical network.
