Microsemi extender doubles reach for PoE midspans

Aug. 11, 2010
The PowerDsine Extender is a Power-over-Ethernet (PoE) midspan that can deliver 25.5 Watts over 200m Ethernet cabling with 10/100/1000 Mbps support.

IRVINE, Calif.--Microsemi Corporation (NASDAQ: MSCC), a manufacturer of analog/mixed-signal integrated circuits, high rel semiconductors and RF subsystems, has introduced its single-port PD-PoE extender, whcih doubles the powering reach of PoE midspans to 200 meters.

The company claims the device is the first of its typed to deliver 25.5-watt, IEEE802.3at power levels over extended distances while supporting 10/100/1000 Mbps data rates. Even longer reach is possible by cascading multiple extenders, notes Microsemi.

“The PowerDsine PD-PoE Extender provides a cost-effective way to extend the Ethernet network range beyond 100m for both standard power devices as well as high power, IEEE802.3at-2009 devices such as Pan-Tilt-Zoom network cameras and IEEE802.11n WLAN access points,” says Sani Ronen, senior product marketing manager, Microsemi PowerDsine Midspans.

He continues, “Our new PoE extender enables both data and power to be delivered up to a distance of 200m while complying with relevant standards. Other products can only deliver 15.4 watts over these distances for standard-power, IEEE802.3af applications.”

Microsemi’s PowerDsine PD-PoE Extender does not require local power, and is simply connected to a midspan and powered via the PoE input. The extender joins Microsemi’s family of midspan products that support up to 24-port implementations in both standard- and high-power applications with a variety of smart power management and remote maintenance capabilities. The midspans enable both data and power to be delivered over a single standard RJ-45 cable, eliminating the need for external power supplies and their associated AC/DC power cabling, while providing affordable, safe and reliable power over existing Ethernet infrastructures.

The Microsemi PD-PoE Extender is available now and priced at $159. Contact information can be found at http://www.microsemi.com/contact/contactfind.asp. Product specification and application whitepapers are available. Additional information is available at Microsemi's website www.microsemi.com.
