The Sola STD-PoE series is designed to work on Category 5 PoE transmission lines as well as Category
6 applications. They feature both female and to female and male to female RJ-45 connection options
for ease of installation. The STD-PoE series is ideally suited to protect expensive equipment and critical
communication/data transfer from internally generated transients and noise.
Power-over-Ethernet is a technology for wired Ethernet LANs (Local Area Networks) that allows the
electrical current, necessary for the operation of each device, to be carried by the data cables rather
than by power cords. This is minimizes the number of wires that must be strung in order to install the
network. The result is lower cost, less downtime, easier maintenance, and greater installation flexibility
than with traditional wiring.
Power-over-Ethernet (PoE) allows users to power devices over Ethernet cabling, it provides power and
networking over a single cable. PoE have tremendous advantages in industrial applications, it permits
users to power devices over the Ethernet cables. The ease of combining signal and power in a single
Ethernet cable connection is contributing to the already rapid evolution of Ethernet based industrial
control systems. Category 5e and Category 6 commonly known as Cat5e and Cat6 are the most widely
used Ethernet connectivity method on the market today. Cat5e and Cat6 are defined in ANSI/TIA/EIA
568-B standard for Unshielded Twisted Pair Cabling.

Theory of Operation
Surges in the positive direction are forced through the positive steering diodes, then clamped by the
SADs, through the negative diodes and back to the source. Hence, negative surges are forced through
the negative steering diodes and back to the source.
Ethernet systems are closed systems. That is, there is no direct connection to either the public
communication system or the electrical distribution network. This limits the magnitude and probability
of high-energy transients, but does not decrease the probability of internally generated transients. The
protection circuitry of the Sola STC-PoE Series provides protection between each conductor in a set, as
well as each conductor set for signal circuits, and finally, each conductor set designed to carry
DC power.
