Microsemi Corporation, a manufacturer of high performance analog mixed signal integrated circuits and high reliability semiconductors, has added a new single-port gigabit power over Ethernet (PoE) midspan to its PowerDsine product portfolio.

The latest member of the PowerDsine 3000 midspan family is designated the 3001G. The solution eliminates the need for external power supplies at remotely deployed Wireless LAN access points and other low-density networks having 10/100/1000 Base-T Ethernet-connected devices.

The 3001G is fully compliant with the IEEE 802.3af PoE standard and can provide remote power to either 802.3af-compliant or pre-standard devices. Users can leverage the solution’s interlocking feature to scale WLAN deployments by linking together multiple one-port midspans as new devices are added to the network.

Thanks to the interlocking feature, users no longer have to deal with conventional single-port power injector solutions that do not interlock and often cause troublesome entanglement of wires with the addition of new devices.

The 3001G midspan provides a cost-effective way to distribute back-up power to every WLAN access point in the network when combined with a centralized UPS power supply. This capability increases service reliability by ensuring continued operation in the event of power failures.

“We realized that the market needed an affordable product that will provide power to low-port density Gigabit deployments,” said Steve Litchfield, president of Microsemi’s Analog Mixed Signal Group in a press release.

He continued: “The 3001G offers a compact, highly scalable solution that is ideal for growing businesses that want to deploy wireless LAN access points, network cameras, and a myriad of other gigabit Ethernet-connected devices in a cost-effective way.”

PoE is a technology for wired Ethernet that allows the electrical power necessary for the operation of each end-device to be carried by data cables, rather than by separate power cords. Since this technology minimizes the number of wires used to install the network, it provides lower cost, reduces downtime, easier maintenance and greater installation flexibility.

Microsemi is a designer, manufacturer and marketer of high performance analog and mixed signal integrated circuits and high reliability semiconductors. The company’s semiconductors manage and control or regulate power, protect against transient voltage spikes and transmit, receive and amplify signals.
