10BASE-T1L Single Pair Ethernet by Graphics

This graphic-based story provides an image-driven overview of 10BASE-T1L Single-Pair Ethernet (SPE), which helps facilitate the use of predictive maintenance, Industrial IoT (IIoT), and the gathering of meaningful operational data for automation across the entire industrial enterprise.

SPE Explained - What Is 10BASE-T1L Single Pair Ethernet?

What Is 10BASE-T1L Single Pair Ethernet?

As opposed to standard ethernet, with either two or four twisted pairs, single pair ethernet uses two copper wires.

Just Two Wires for Data and Power Transmission

Just Two Wires for Data and Power Transmission

The single, twisted-pair cable carries power to enable the powering of remote sensors and actuators and also both transmits and receives data.

Thin Cable Diameter = Less Weight

Thin Cable Diameter

The thinner cable diameter offers less weight which translates to easier mobility, less space, faster installation, and lower costs.

    
Smaller, Simplified Connector

Smaller. Simplified Connector

The smaller connector footprint takes up less space on a PCB, simplifies design, and shows increased connector stability.

    
Increased Range & Speed

Increased Range

Unlike four-pair cable which has a distance limitation of 100 meters, 10BASE-T1L SPE offers 1000-meters.

Easier Sensor Integration

Easier Sensor Integration

Simplifies communication from sensor to local server or cloud and works without additional gateways or interfaces.

    I'm really excited about SPE as a technology, especially when combined with IEEE1588 & PoDL, but man is it ever hard to find documentation about how to work with PoDL to implement a powered device, how to ensure that a powered device is compliant (eventually it sure would be nice to just be able to buy a PoDL switch, right?), how to make PoDL PSE/gateway hardware and so on - it looked like Analog had a app note coming for a while, but that seems to have vanished along the way somewhere.

    Do you know of any good resources for PoDL design, compliance, and implementation? Do you guys have any PoDL devices in the works that small-timers could use as a development platform or reference design?

    easier then connectors: just bare wires inserted into spring-loaded pcb-terminal-clamps would be a really nice option if there were a way to also get this shielded.. for industrial this would make sens as it cuts down on material and labor cost for the filed setup...

    how much power can be transmitted?

      SPE user "power-over-data-line" (PoDL) and supports 60W of power delivery.

    Beyond prototyping, what are the options for cable runs right now? Are there crimping tools? Do these need to be ordered pre-terminated at specific lengths? Are there direct burial options available yet?

    How did Sparkfun do their long cable run for the pump monitor?

      Tools and cables are available from various vendors. Our partner on this project, Harting, has a range of tools, cables jacks.

      for our demo, we use a long, pre-built SPE cable from Harting.
