PoE midspan power injector with integrated lightening protection from Microsemi

Microsemi has introduced the new power over Ethernet (PoE) midspan power injector that provides integrated protection from lightning strikes.

The new PowerDsine 9001G-40/SP is a single-port, high-power Gigabit solution for remotely powering both current and emerging high-power networking terminals and equipment while also providing surge protection optimized for outdoor devices such as security cameras and wireless LAN access points.

The PoE could only be deployed safely outdoors with a surge-protection unit to prevent direct or nearby lightning strikes from damaging or destroying both the powered devices and their network switch.

The key features of PoE Midspans are,

Interoperability with IEEE802.3af and IEEE802.3at devices
Lightning protection up to 2500V/500A
10/100/100-BaseT support

"A high percentage of outdoor PoE installations, especially in the enterprise, do not implement surge protection units because of their high cost or a lack of awareness," said Sani Ronen, senior product manager for Microsemi's PowerDsine midspans. "Nearby lightning strikes are much more common than most people think. Strikes as far as a mile away can induce a voltage level that can damage outdoor devices. Without lightning protection, surges also can move quickly along the Ethernet cable to damage expensive indoor network switches. Our new midspan delivers that protection at a cost savings of as much as 50 percent."

"The 9001G-40/SP was designed to deliver the latest benefits of the new high-power 802.3at standard while also offering a cost-effective, single-box solution for powering and simultaneously protecting outdoor PoE systems from lightning damage or destruction," Ronen said.

Price:
PD-9001G-40/SP Midspan: Unit list price of $119
Surge and lightning protection units: From $250 to $400
