IEEE 802.3af Power over Ethernet Standard Approved
Global Standard Expected to Accelerate Deployment of Power over Ethernet
London, UK - June 23, 2003 - PowerDsine®, the leading provider of Power
over Ethernet (PoE) technology, today announced the approval by the
Institute of Electrical and Electronic Engineers (IEEE) of standard
802.3af-2003 , which defines the specifications to deliver power over
standard Ethernet cables. PowerDsine has been a major contributor to the
802.3af Task Force, and participated in the Call for Interest in the 802.3
Working Group in 1999.
The standard was approved by the IEEE Standards Board on June 12, 2003, and
will be published on or before July 11, 2003, as "802.3af-2003." PowerDsine,
has played a significant role in the creation of the standard, and has also
pioneered a service to Ethernet device manufacturers and switch vendors to
test conformance with the provisional standard. To date, over one hundred
terminal devices have been compliance tested by PowerDsine, including most
of the leading Voice over Internet Protocol (VoIP) phones, wireless LAN
access points and IP security cameras.
"The 802.3af standard will provide the first global standard for power,"
stated Steve Carlson, Chair of the 802.3af Task Force, "Thousands of new and
innovative products will emerge to take advantage of having the proven
robustness and reliability of Ethernet along with power on the same
connector. In ten years no one will be able to remember when Ethernet ports
didn't supply power."
Richard Webb, Market Analyst for Infonetics Research, commented: "The
802.3af standard provides a stable basis from which vendors can continue to
reduce the cost of installing and upgrading network devices; this can be a
hidden cost in the deployment and scaling-up of wireless LANs and VoIP in
particular, and so improves the investment case for both these technologies.
PowerDsine's strong contribution to this standard shows them to be the key
innovator in the Power over Ethernet field."
"The standard ratification will add extra impetus to the current trend
amongst silicon vendors to design chipsets for laptops and portables that
require low power consumption below the 12.95W prescribed in the Power over
Ethernet standard," said Amir Lehr, vice president, business development and
strategic planning at PowerDsine. "As these devices become less power-hungry
and Power over Ethernet becomes the standard in most corporate IT
environments there will no longer be a need for business people to carry a
variety of different plugs when travelling. Instead the RJ45 jack will
become the universal power jack. I confidently predict that in the next
five years more than 75% of enterprise network devices will be able to be
powered by Ethernet..."
Power over Ethernet is already widely adopted in the market, particularly in
the VoIP, wireless LAN and IP Security market where it saves up to 50% of
the overall installation costs by eliminating the need to install separate
electrical wiring and power outlets. Its other major advantage,
particularly for IP telephony and surveillance camera users, is the ability
to offer continuous operation even in the event of a power failure by
delivering battery-backed-up uninterrupted power via the local area network
Power over Ethernet has been widely deployed in two formats either as
endspan devices, i.e. embedded into switches, or as stand-alone midspan hubs
from companies such as PowerDsine, allowing terminal devices to be
power-enabled without upgrading the existing switches. The new standard will
cover both categories of Power over Ethernet technology.
Yair Darshan, chief engineer at PowerDsine adds, "A great deal of attention,
analysis and field tests were invested in the standard in regard to system
design aspects to ensure reliable and robust operation of the system
functions. This was the base of this technology which boasts business
benefits that have already seen widespread deployment. The standard
ratification provides extra momentum as it provides companies with
investment protection in the knowledge that they won't be tied into any one
vendor. It's also likely to be a spur to exciting new product innovations."
PowerDsine is the leading player in Power over LAN(tm) technology providing
the ability to deliver both power and data over a single network cable.
PowerDsine offers converged power and data solutions to corporate users via
it own range of equipment and via OEM agreements with the leading
communications equipment manufacturers in the telecom and datacom
industries. PowerDsine's product line offers a variety of Power over LAN
midspan devices as well as integrated solutions, which are embedded directly
into Ethernet switches. PowerDsine is a founding member of the IEEE 802.3af
Task Force. For more information, please visit http://www.powerdsine.com
About IEEE 802.3af Standard
802.3af addresses and defines the following issues:
Legacy Installation - Power over Ethernet ensures safe delivery of power to
existing legacy devices as well as power-enabled terminals.
Preservation of Cabling Infrastructure - PoE avoids altering existing wiring
and does not damage cabling infrastructure already in place.
Data Integrity - Power delivery over Ethernet cables does not cause data
degradation or loss of data integrity.
