You may have heard that we have too much bandwidth in
existing networks, but it is not the case. We are far from having too much
bandwidth, and in fact, I will go out on a limb and say that you can never
have too much. Bandwidth hungry apps seem to materialize faster than new
and bigger pipes can be created. In the consumer space, music swapping and
now movie swapping are taking up hordes of bits per second while
enterprises roll out new applications like video, VoIP and collaboration
that are taxing last-mile pipes like never before.
Service providers are always looking for ways to do
more with less. One area of extreme savings is using existing resources
more effectively. One resource that many service providers have in
abundance is copper. In fact, there are about three billion copper lines
installed in the world. A company called Actelis Networks (news)
has come up with ways to deliver near-fiber speeds over these POTS quality
lines. Using their technology, you are able to drastically increase the
number of customers served and thus increase revenue density. The company
says you can serve almost twice as many customers from the same CO space
using their special division multiplexing technology. This performance is
achieved while conforming to G.SHDSL.bis physical layer technology as well
as emerging standard bonding schemes.
In order to achieve these feats, Actelis has
developed technology to reduce cross-talk by focusing on cancellation and
management of this dreaded nuisance plaguing high-speed copper
communications. When this technology is maxed out you can achieve speeds
of 67 Mbps, an astounding speed. It is possible to reach 45 Mbps with ten
copper pairs, but obviously line conditions and length are factors that
must be considered in such an equation. The company is also working to
increase bandwidth levels.
Actelis is working with a number of standards bodies
to make sure they conform to the latest standards. Here is a brief
There are a number of different solutions that
Actelis offers depending on your needs, budget and bandwidth requirements.
The MetaLIGHT product lines come in three flavors, while there are two
devices in the MetaLIGHT Transport line. In an age of increased service
provider opportunity where there is still a focus on keeping a lid on
costs, increasing copper capacity makes a great deal of sense. You really
can�t be too thin or have too much bandwidth. To learn more about one of
the ways this can be accomplished (not the thin part) contact
Actelis Networks directly.
