IRVINE, Calif., Apr 26, 2010 (GlobeNewswire via COMTEX News Network) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, today announced the world's most efficient single port Power-over-Ethernet (PoE) midspans, featuring lowest power consumption in both no-load and load conditions.

Designated the PowerDsine(R) PD3501 and PD3501G, Microsemi's new single port midspans offer compact and cost effective, fully IEEE 802.3af compliant solutions for remotely powering wireless LAN access points, IP security cameras, VoIP phones, access control systems and other low port density installations.
