New to Power-over-Ethernet or PoE Testing?

Power-over-Ethernet (PoE) is a growing industry standard for powering devices that require both a data connection and power using the standard Ethernet cabling. The IEEE 802.3at and 802.3bt standards enable the safe and reliable addition of power up to 90 watts per network link layered onto existing or newly installed Ethernet cable systems. Networked devices including phones, wireless access points, cameras, lighting, displays, smart terminals, and many other categories can be installed and powered without the need of electrical services or batteries.

IEEE standards refer to PoE sources as Power Sourcing Equipment (PSE) and to power consumers as Powered Devices (PD). Both PSE’s and PD’s need to adhere to a complex set of specifications in order to assure safe, reliable powering that does not adversely affect non-PoE equipment and data transmission integrity across links up to 100 meters in length. Testing to assure specification compliance can be a challenging and burdensome task on both the PSE and PD side.

Sifos provides solutions that have become the industry standard for highly automated, plug’n play PSE and PD analysis and specification conformance verification.

Sifos Approach to 10/100/1000Base-T Test

10/100/1000Base-T interfaces make up the vast majority of wired Ethernet connections.  Despite the maturity of this technology, it continues to proliferate into more and more applications and networking environments.

While it may be easy to presume that 10/100/1000Base-T interfaces are readily implemented, the fact remains that 10/100/1000Base-T is a complex grouping of technologies that are difficult to test in a way that assures interoperability with all other networked devices operating in all connection environments described under IEEE 802.3 standards.   Furthermore, the published methods of performing interface testing are often restricted to elemental design phases and are not workable in finished product.

Sifos provides a highly innovative, plug’n play, and fully automated solution for 10/100/1000Base-T interface qualification that works with finished products and evaluates interface transmission and receiver characteristics including basic auto-negotiation characteristics.
