Today, Microsemi is launching a new line of midspans which feature integrated lightning protection. This marks the first time a PoE midspan features lightning protection. As more and more PoE devices are used outdoors, including outdoor wireless Access Points (APs), outdoor security cameras, and more, having
lightning protection is critical. One lightning bolt strike and it can wipe out your entire networking and IT infrastructure. While lightning is great & all since it bestows Captain Marvel his super powers, when it comes to networking equipment, not so much.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.

According to Microsemi, "Until now, PoE could only be deployed safely outdoors with a costly surge-protection unit installed alongside it, to prevent direct or nearby lightning strikes from damaging or destroying both the powered devices and their network switch. Surge and lightning protection units can cost from $250 to $400."
"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."
Microsemi's newest midspan has been tested successfully to the GR-1089 lightning standard for surges up to 2500V/500A. It can power devices designed for either the IEEE 802.3af standard, or the recently ratified IEEE802.3at standard for high power over Ethernet applications.
The 9001G-40/SP offers up to 40W of power which means it can support power-hungry devices such as 802.11n access points, pan-tilt-zoom cameras and WiMAX customer premises equipment.
"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.
