10GigaBit Over Copper!
Bandwidth... Bring It On...
10Gigabit Ethernet is an emerging technology
offering data speeds up to 10 billion bits per
second. This latest standard has been driven not
only by the increase in normal data traffic but also
by the proliferation of new, bandwidth-intensive
applications.
At the recent IEEE 10Gigabit/s Ethernet standard
working group meeting it was announced that
international structured cabling company KRONE
had made a breakthrough. The company has
demonstrated the first augmented Category 6
cable in the world with the necessary characteristics
to enable 10Gigabit/s Ethernet to be implemented
over unshielded twisted pair (UTP) to the full 100
meters required for structured cabling systems.
The test results on KRONE’s new cable were
independently confirmed by one of the leading

Ethernet electronics vendors involved in the
development of 10Gigabit/s technology and the
10GBASE-T Ethernet standard. Presenting the
results, KRONE’s Senior Project Manager Bernie
Hammond said, “Our presentation to the IEEE
today shows that KRONE has demonstrated its
ability to produce a UTP cable that exceeds the
requirements outline to run 10Gigabit/s Ethernet
over a 100-meter, unshielded twisted-pair copper
channel.” Most industry experts had concluded that
it would be extremely difficult to overcome the
technical combination of insertion loss and alien
cross talk, or interference from adjacent cables,
with UTP cable - the most prolific type of enterprise
networking cable in the world.
“By demonstrating that 10Gigabit Ethernet can
be achieved over UTP cabling, our engineers have
once again demonstrated KRONE’s unmatched
commitment to technological innovation,” said
KRONE’s President and Chief Operating Officer Ron
Lowy. “We are delighted to be the first in the world
to reach this remarkable milestone.”
This new augmented Cat 6 UTP copper cable was
designed and developed at KRONE’s U.S. copper
cable-manufacturing facility in Sidney, Nebraska.
The cable demonstrated Shannon Capacity of
21Gigabit/s due to the improved alien cross-talk
immunity and the reduced insertion loss - which is
more than adequate for the 10Gigabit/s Ethernet
implementations being considered by the IEEE

standard working group.
With the onset of IP convergence, bringing a
wealth of voice, video and data services to a single
cable infrastructure, bandwidth demand hand in
hand with network reliability and Quality of Service
(QoS), will drive increasing bandwidth requirements
to the desktop.
The emergence of grid computing will be a key
technology that, in the not too distant future, will
drive bandwidth requirements into the horizontal
cable infrastructure. Grid computing will essentially
“cluster” together desktop workstations and PCs to
contribute idle CPU cycles to create a large, virtual
server where performance scales as more users are
added. This technology may supplant centralised
servers allowing for the creation of very powerful
virtual servers scaling to user requirements. In
essence the horizontal network connectivity
between desktop workstations becomes an
external high speed server bus. Thus the
requirement for bandwidth and reliable, error free
processing will be pushed out to the desktop
network interconnect.
Only KRONE’S TrueNet
®
zero bit error rate cabling
solution coupled with this latest announcement
regarding demonstrable 10Gigabit Ethernet
capability will provide the necessary infrastructure
to enable cost effective grid deployment across

organisations.
