Background and History of T1 Industrial Ethernet

SPE Explained: What are the Speeds and Distances Possible with Single Pair Ethernet?

T1 Industrial® Introduction

The first Single Pair Ethernet starting point was released by Broadcom in 2011, called BroadR-Reach®, supported by industry leading automotive and technology companies. Single Pair Ethernet was standardized in 2015 within the IEEE sub-group 802.3bw. This group outlined that two-wire technology could reliability and consistently reach speeds of 100Mbit per second at 15 meters when using an unshielded cable, and 40 meters when using a shielded cable with a bandwidth across both lengths of 166 MHz. HARTING saw the capabilities possible of this new physical media, as well as the need for more speeds and varying lengths for different application, and knew that a common mating interface would be essential to the success of the technologies implementation globally. R&D began in late 2015 at HARTING’s global headquarters in Espelkamp, Germany to develop this common industrial standard.

Industrial Ethernet Solutions and Infrastructure

In production, nothing causes more excitement than when everything is in place. This is particularly annoying if it is due to a small building block in the infrastructure that cannot withstand the tough demands. To prevent this from happening in an SPE ecosystem, the T1 Industrial Ethernet connector is very robust. The shield plates are made entirely of stainless steel. A robust core and a reliable cable gland ensure enough stability at the field level and other hard locations.

T1 Industrial Ethernet Standards

For HARTING, SPE is a technology topic and the starting point for many new product developments

T1 Single Pair Ethernet EcoSystem

Standardized and uniform interfaces are the key to enabling manufacturers to jointly develop the SPE EcoSystem consisting of sensors, actuators, controllers and connection technology and to enable users to create suitable automation solutions from these components.

Breakthrough Single Pair Ethernet Technology

Development of Single Pair Ethernet for industrial manufacturing markets began in 2015 after seeing the potential in the Automotive sector. This section will outline the reasons why the market began development of Single Pair Ethernet, its advantages over other communication protocols currently in use, and the future of Single Pair Ethernet speeds and distances.
