Excerpt:
Competitive Carriers Hone their Ethernet over Copper Skills

Fiber likely will be the ultimate endgame to
deliver Ethernet services to businesses. Offering unlimited amounts of
bandwidth, incumbent and even competitive service providers have spent
billions of dollars building out fiber to large business customers
that need large amounts of bandwidth and are willing to pay for it.
However, the reality is that even though service providers are
multitasking their networks to serve various needs, including
enterprise customers and even wholesale opportunities like wireless
backhaul, they can't build fiber everywhere.
While fiber penetration into U.S.-based
buildings has increased in recent years, a recent report conducted by
Vertical Systems Group revealed that only 27.7 percent of U.S.-based
buildings have fiber, meaning that the remaining 72 percent don't have
fiber in their buildings yet. Likewise, in Europe only 18.4 percent of
buildings have fiber in them as well.
One way to close the so-called fiber gap to serve customers that want
Ethernet is the advent of Ethernet over Copper (EoC). Once thought of
as a small niche product, EoC enables service providers to leverage
the near-ubiquitous copper plant that's already in the ground.
While incumbent players are quietly offering EoC services, a growing
group of competitive service providers--including Integra Telecom,
PAETEC (Nasdaq: PAET) (via its Intellifiber subsidiary), MegaPath,
TelePacific, and XO Communications (OTC BB: XOHO)--have been driving
the EoC market with ongoing deployments in their network footprints.
Despite the obvious limitations with copper-based facilities, the
advent of new technologies, including pair bonding, NxT1 bonding,
VDSL2 and vectoring are pushing the boundaries of data rates delivered
over copper. Couple these new innovations with a growing audience of
businesses that want to have a service medium that allows them to
scale bandwidth more flexibly than purchasing more expensive T1
circuits beyond 1.5 Mbps, EoC has a long life ahead of it.
