Sifos Technologies

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.

Core offering

Sifos Technologies designs and manufactures automated test and measurement instruments for Power over Ethernet (PoE) Power Sourcing Equipment (PSE) and Powered Devices (PD), as well as Ethernet 10/100/1000Base-T physical layer interfaces. The portfolio includes the PowerSync Analyzer, PowerSync Programmable Load, Powered Device Analyzer, MPD-600 Evaluating PSE, and PhyView Analyzer families, supported by proprietary conformance test suites, LLDP emulation software, and automation tools supporting IEEE 802.3af, 802.3at, and 802.3bt standards.

Product overview

Sifos Technologies offers a comprehensive portfolio of test instruments and software for Power over Ethernet (PoE) and Ethernet 10/100/1000Base-T interface testing. The product architecture consists of hardware test instruments supported by productivity software suites. The PowerSync Analyzer family (PSA-3000, PSA-3402) and PowerSync Programmable Loads (PSL-3424A/L/M, PSL-3000) address PSE (Power Sourcing Equipment) testing with automated conformance test suites for 2-pair and 4-pair configurations supporting 802.3at and 802.3bt standards up to 90W. The Powered Device Analyzer family (PDA-604A, PDA-602B) provides PD testing with corresponding conformance suites. The MPD-600 Evaluating PSE is a unique multi-port switch for PD qualification. The PhyView Analyzer family (PVA-3000, PVA-3002) offers 10/100/1000Base-T interface testing with the PHY Performance Test Suite. All instruments are managed through PSA Interactive (GUI) and PowerShell PSA (script automation) software platforms, with optional test suites for conformance, LLDP emulation, and power management analysis.
