Poll: How Significant is Single Pair Ethernet Technology to Engineers and the Industry?

Ethernet has been the go-to communication and network protocol in LAN applications for decades It enables the seamless data transmission via TCP/IP. But Ethernet is evolving from the 4- and 8-wire cabling systems to simpler two-wire cabling, called Single Pair Ethernet technology.

I‘m looking forward to seeing this get rolled out. For a lot of uses, the SPE at 10 Mbps is ’good enough’. I don’t need Gbps for everything. I like the idea of the 1000 meter range of it, for use in sensor…

Ethernet was always expected to expand beyond the initial implementation both for more complex and more simple connections. The initial design envisioned tapping into small computers at low data rates…

Hi Everyone,

The HARTING SPE connector and cable assemblies were officially launched to the market earlier this month. Feel free to contact the HARTING tech support team if you have any particular questions. I will be posting all of the new content on our HARTING Element14 Page.

In automotive, this is the only kind of ethernet you find - the two-wire twisted pair. They want things to be light and robust in cars. The connectors are not the standard ethernet connectors, but something called "fakra".

What we need now is cheaper and more readily available cables, switches, routers, and USB 100/1000base T1 Ethernet adapters. They are still quite expensive.

The 2 wire Ethernet also brings in new features, like AVB, which isn't very widely supported yet.

I agree with mp2100 that single pair Ethernet will displace profibus and fieldbus - and LONWorks and BACNet. We will probably still keep their networks as they can be integrated into the larger system, but bandwidth considerations and security should keep them separated - at least for a while.

Ethernet was always expected to expand beyond the initial implementation both for more complex and more simple connections.

The initial design envisioned tapping into small computers at low data rates to huge complexes of multiple lines to achieve high bandwidth.

We are just seeing the standard being implemented as intended.

I like the idea of the 1000 meter range of it, for use in sensor networks. That’ll save me from having to install a lot of fiber optic cables. It will replace profibus and fieldbus.
