What Sifos Technologies does
Sifos Technologies, Inc. is a privately held test and measurement company founded in 2003 and headquartered in Andover, Massachusetts. The company develops automated hardware instruments and supporting software for verifying Power over Ethernet (PSE and Powered Devices) and 10/100/1000Base-T Ethernet physical layer interfaces, targeting IEEE 802.3af/at/bt/bu conformance and interoperability workflows. Its product architecture comprises five hardware families — PowerSync Analyzer (PSA-3000, PSA-3402), PowerSync Programmable Load (PSL-3424A/L/M, PSL-3000), Powered Device Analyzer (PDA-604A, PDA-602B), MPD-600 Evaluating PSE, and PhyView Analyzer (PVA-3000, PVA-3002) — managed through PSA Interactive GUI, PowerShell PSA automation, and PDA Interactive software, with optional licensed test suites for conformance, LLDP emulation, and power management analysis. The platforms support up to 24 ports per chassis, scaling to 96 PoE ports in system-level configurations, and are Ethernet Alliance certified for both Gen 1 and Gen 2 PoE logo testing.
Sifos generates revenue through hardware sales of test instruments, one-time and subscription licenses for conformance test suites and software, factory calibration services traceable to standards, and tracking service agreements for ongoing software updates. Pricing is quote-based and not publicly disclosed, with multi-year enterprise contracts. The company sells through direct enterprise field sales supplemented by an extensive global network of regional channel partners spanning more than 40 countries across North America, Europe, the Middle East, Asia Pacific, and Oceania. Its customer base is horizontally segmented across network equipment manufacturers, semiconductor vendors, electronic contract manufacturers, independent test labs, service providers, system integrators, field service organizations, and enterprise IT departments — all of whom require PoE and Ethernet PHY conformance and interoperability verification.
