Microsemi Announces Digital Ceiling Power-Over-Ethernet Switch Offering Optimal and Cost-Effective Solution for PoE Lighting and Other Digital Ceiling Applications

Unique Switch Compatible to Any IEEE802.3af/at Lighting Fixture Provides New Features and Power Savings

ALISO VIEJO, Calif.,Jan. 30, 2018/PRNewswire/ -- Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today announced the availability of its PDS-208G power-over-Ethernet (PoE) switch. Offering an optimal and cost-effective solution designed specifically for digital ceiling installations, the new device is compatible with any IEEE™ 802.3af or 802.3at PoE lighting fixture and can be installed in ceiling or communication room racks.

"Our new PoE switch is a unique offering from Microsemi, as it is differentiated from enterprise switches by enabling lighting fixtures and other Ethernet terminals to receive power and data over standard Ethernet cables in the most efficient manner possible," said Sani Ronen, director of product management for Microsemi's PoE systems. "Leveraging our leadership position in PoE technology, the device's high-power efficiency results in minimal losses to ensure the support necessary for digital ceiling applications, enabling installation of connected lighting systems that offer improved lighting experience, new features and power savings."

Microsemi's new PDS-208G PoE switch, which was installed in multiple successful beta sites in 2017, is well-suited to a number of applications within the LED lighting and enterprise markets, such as smart buildings. The 240-watt (W) fanless switch supports full-power mode by providing 30 W for eight ports simultaneously and any individual port can operate at up to 72 W. The device is also able to perform software upgrades while keeping PoE ports active.

According to market research firm MarketsandMarkets, the total smart lighting market size is expected to reach a value of $19.47 billion by 2022, at a compound annual growth rate (CAGR) of 27.1 percent. In terms of volume, it expects the market size to reach 1.27 billion units by 2022, at a CAGR of 71.3 percent during the forecast period. With growing demand for energy-efficient lighting systems expected to be the major factor driving the market, Microsemi's PDS-208G PoE switch is ideally suited to capitalize on this growing demand.

The highspeed PDS-208G PoE switch offers Layer 2 management capabilities, and the device's eight 10/100/1,000 megabits per second (Mbps) ports with PoE capabilities are based on Microsemi's energy-efficient four-pair PoE technology, enabling 50 percent power loss savings on the Ethernet cables when compared to similar installations using an Ethernet switch. It also features two Gigabit ports which can be used for uplinks and can be remotely managed through Simple Network Management Protocol (SNMP) and the web.

Smart Lighting Solutions

Energy expenses can skyrocket due to over-illumination of smart buildings, city street lights and home lighting fixtures. This has created a challenge for enterprises increasingly connecting everything into a vast Internet of Things (IoT), as well as cities attempting to create an inviting and safe environment for residents. The low cost and high performance of Microsemi’s smart lighting solutions provide a more cost-effective energy output, ultimately improving lighting infrastructure and decreasing the total cost of ownership (TCO) over time.

Digital ceiling applications in smart buildings demand solutions that enabling an effortlessly built Ethernet infrastructure that supports both data and power in for IP-based luminaries. Easy installation, coupled with centralized management, simplifies setup and offers hassle-free maintenance.

Microsemi’s Power of Ethernet (PoE) solutions for LED lighting greatly improve the standby power of a typical application. With the large number of ports in an application, reducing this standby power is critical. Microsemi PoE solutions reduce the parameter to 10 mW consumed to keep the port alive, which is 10 times better than current competitor solutions. With its ability to deliver power and data over a single cable, using PoE in smart lighting applications greatly simplifies deployment and management over a unified infrastructure.
