Heavy Networking 642: 10Mbps Single Pair Ethernet

Single pair Ethernet. That’s right. Ethernet over a single twisted pair, rather than the four you’re used to. Or two if you’ve got a little gray in your beard. Now, single pair Ethernet isn’t fast in the way we network engineers would normally think of fast. SPE runs at 10 megabits per second. But in the use cases SPE was designed for, 10Mbps is very fast indeed. To tell us all about single pair Ethernet is Peter Jones. Although Peter wears many hats in the networking industry, today he comes to the microphone as the chairperson of the Ethernet Alliance. What We Discuss * In a nutshell, what is Single Pair Ethernet? * Where are we likely to see SPE deployed? * There are two 10Mb/s SPE standards, 10BASE-T1L & S. Summarize each of these for us. * Let’s talk standards. Discuss IEEE standard 802.3cg plus 10BASE-T1L & S. * Why do we need this flavor of Ethernet? What problems are being solved? * Power over SPoE. Why is this such a big deal? * What are the technical highlights of power delivered via SPoE? * How far away are we from devices that support SPE & power over SPE? * Should we potential consumers of SPE devices on OT networks be asking our vendors for SPE?
