Microsemi, a manufacturer of high performance analog mixed-signal integrated circuits, high reliability semiconductors and RF subsystems, has introduced a compact, four-port Power-over-Ethernet (PoE) midspan designed to power a wide range of network devices in low-density applications.
According to company, the new PowerDsine PD-3504G midspan is fully compliant with IEEE 802.3af specifications to safely power wireless LAN (WLAN) access points, IP security cameras, VoIP phones, access control systems and other devices over existing standard Ethernet cabling.
The new four-port PoE midspan joins the company’s single-port PD-3501 and PD-3501G products for low density installations, and enables delivery of both data and power over a single standard Ethernet cable, eliminating the need for an external power supply and its associated AC/DC power cabling.
The company claims that PD-3504G PoE Midspan provides a compact, affordable, safe and reliable power-delivery solution over the existing Ethernet infrastructure and supports Gigabit Ethernet data transmission, enabling it to power 10/100/1000Base-T network devices including wireless IEEE 802.11n access points and wireless WiMAX access points.
The PD-3504G features 10/100/1000-BaseT support; high power efficiency; delivers 15.4W per port for all ports; powers pre-standard devices including Cisco equipment; and includes per-port, concise LED visibility.
Sani Ronen, senior product line manager for PowerDsine midspans at Microsemi, said: "We are pleased to offer our customers the newest addition to the PowerDsine family of midspans.
"The PD-3504G will enable cost-effective PoE deployment in small to medium-sized business applications, while also offering an improved power efficiency scheme.
"The PD-3504G product also offers the well known PowerDsine quality, reliability and superior performance–including full data integrity in 10/100/1000Mbps applications–plus the market’s highest margins for meeting EMI Class B requirements."
