Outdoor lightning protection device aimed at Ethernet sol'ns

Microsemi Corp. has released what it says is a high reliability, outdoor-rated lightning protection device that supports both Power-over-Ethernet (PoE) and non-PoE enterprise installations. The PD-OUT/SP11 is a single-port device that secures all eight wires of the Ethernet cable while enabling data streams of up to 10/100/1000Mb/s and PoE levels up to 95W.

The device is optimised for outdoor devices such as security cameras and wireless LAN access points (AP) and features lightning protection up to 10kV. According to market research firm Infonetics, around 300,000 outdoor WLAN APs are expected to ship in 2014, growing to 650,000 in 2018.

The national weather service reported there are about 23 million lightning strikes per year in the U.S. Most of the existing Ethernet lighting protection devices are indoor, which limits the location of the protection and installation to the indoor environment only. The PD-OUT/SP11 is outdoor-rated and therefore can be installed in the optimal location, the exact point the Ethernet cable is entering the building, resulting in maximum protection from lightning hitting the outdoor devices or the outdoor cable.

Microsemi's latest product can be installed in PoE environments or in non-PoE environments and is vendor agnostic, meaning the switch and the PoE solution can come from any vendor. The PD-OUT/SP11 has been tested successfully to the GR-1089, IEC61643-21 and ITU-T K.45 lightning standard. The device's low capacitance ensures data rates of up to 1Gb/s will pass through with no interruption. In addition, PoE levels of up to 95W can pass through the SP11 device (supporting IEEE 802.3af, IEEE802.3at and HDBaseT).

The PD-OUT-SP11 is geared to protect indoor Ethernet networks from lightning that may come from the outdoor environment through the Ethernet cable. The product is enclosed in a metal weatherproof enclosure, meeting IP66. It can be easily mounted on a wall or a pole. The SP device can be installed before the cable enters the building to protect the indoor network or immediately adjacent to the wall- or pole-mounted outdoor device (i.e., WLAN AP, IP camera, etc.).

The PD-OUT/SP11 is available.
