PowerDsine (R). (NASDAQ: PDSN), a pioneer in Power over
Ethernet (PoE) solutions, has announced today an innovative high-power
controller, PD83000, which will support more PoE based devices by
using 4-pairs of Ethernet Cable as opposed to two. This will allow
switch and router vendors to provide higher levels of managed power to
a broadened range of Ethernet devices, such as Video screen phones,
WiMax Transmitters, Pan-Tilt-Zoom cameras and Thin-clients.
New power hungry Ethernet end devices require more than the
current IEEE 802.3af standard15.4 Watts and, because of this, switch
vendors needed a chip that can be used with new and existing switches
that will be able to deliver more watts to power end-evices. The new
chipset can provide switch vendors with a minimum of 30.8 Watts of
power and could potentially reach 56W. Also, when deployed with
PowerDsine's 4 or 12-port chip, (PD64004A and PD64012G respectively)
the new chipset can provide a maximum of 48 high-power ports.
"The market of PoE is always changing. many next-generation
devices that are being created, need for more power to operate. The
new PD83000 chip-set will allow a wider variety of applications to
benefit from the advantages of Power-over-Ethernet," said Amit Gilboa,
Product Marketing Manager of PowerDsine. "The IEEE 802.3af standard is
mainly targeted today at low power-consuming applications such as VoIP
phones, WLAN access points and IP cameras. The PD83000 allows
applications that need more power, such as WiMAX transmitters,
Pan-Tilt-Zoom cameras, Video-phones and Thin-clients, to receive the
necessary power."
"We believe that as Power over Ethernet adoption expands, growing
from Enterprise applications to SOHO and small and medium business
markets and further into Gateways and Routers in the Residential
market, there will be a greater need for powering more Ethernet based
applications that require higher power than what the standard
currently allows today," said Madhu Rayabhari, VP Marketing of
PowerDsine. "The PD83000 will allow switch vendors to offer immediate
solutions to high-power needs, above what can be supplied with a
standard IEEE802.3af solution."
The PD83000 implements a unique synchronization algorithm for the
power-sharing circuitry implemented in the end-device thereby
optimizing the associated costs. The PD83000 also combines data and
status information from the 2 physical ports (data & spare) onto a
single logical port, for ease-of-use by the Switch/Router vendor. The
system is fully backwards compatible with IEEE 802.3af enabled
end-device when used on a single pair and supports all of PowerDsine's
advanced feature set such as Dynamic Power Management, Emergency Power
Management, Port Matrix, Port Priority and LED stream among others.
High-power is achieved by injecting power on the data-pair and on
the spare-pair of the Ethernet cable simultaneously. Using IEEE802.3af
defined parameters a minimum of 30.8W is currently possible. Scaling
the voltage and current to higher values allows for higher power
availability. Such scaling can permit designers to achieve power
levels of up to 56W. Combining power from both the data and spare
pairs is performed at the end PoE end-device.
PowerDsine is also actively participating in the IEEE802.3at task
force, the new PoE high-power standard, to allow compatibility in
future versions of the PD83000 firmware.
Product Availability
The PD83000 will be ready for shipment and production in May 2006.
About Power over Ethernet Technology
PoE is a technology for wired Ethernet, the most widely installed
local area network technology in use today. PoE allows the electrical
power necessary to operate each device, to be carried by data cables
rather than by power cords. It minimizes the number of wires that must
be strung in order to install the network.
PoE also potentially reduces the cost of installing end devices
such as IP phones and wireless LAN access points. Because the network
switches also can deliver power through the standard Ethernet
infrastructure, the need to connect each IP phone or wireless LAN
access point to a separate electrical circuit and install additional
AC power outlets is eliminated. Also, PoE can provide customers with
uninterruptible power for critical applications such as IP (Internet
protocol) phones, security cameras, entry loggers and other powered
data terminals.
