Experimenting With Single Pair Ethernet

Table of contents ...  

Experiment with Single Pair Ethernet to learn its benefits for industrial automation.

Ethernet is the most popular communication protocol today for residential and commercial applications. It's also widely used in industrial automation. Traditional Ethernet uses an 8-wire ethernet cable along with RJ45 cable connectors. Single Pair Ethernet is considered an improvement over traditional Ethernet for a variety of reasons. As the name suggests, Single Pair Ethernet uses only two wires for its data receive/transmit lines, at higher speeds, clearly a key benefit. For Single Pair Ethernet, the cables are smaller and lighter, and a less costly approach to transmitting data over Ethernet. Would you like to learn more about Single Pair Ethernet? Then, read on.

In this Experimenting With Single Pair Ethernet Challenge, participants will receive a kit of Single Pair Ethernet components. Four official applicants will receive a free-of-charge SPE Kit (see below). For a chance to win one of the great prizes in this challenge, a participant must blog about the experiments and/or projects they have created. The Sponsor’s kit must be used in their final project and or summary blog. Creative use of the components and interesting uses of Molex’s SPE connectors and cables are key to winning this challenge.
