CTi Leading the Way with Profinet-Compliant SPE Cables

2026.09.14

 
 

As industrial communication evolves toward simpler, faster, and more efficient connectivity, we'd like to introduce how PROFINET-compliant Single Pair Ethernet (SPE) cables are shaping the next generation of industrial networks and how CTi is addressing these demands with advanced cable solutions.

What is Single Pair Ethernet (SPE), and why is it important?

Single Pair Ethernet (SPE) is an emerging technology in industrial communication that enables high-speed data transmission using just one pair of wires. Compared to traditional Ethernet cabling, SPE reduces size, weight, and overall system cost.
Additionally, SPE supports Power-over-Data Line (PoDL), allowing both data and power to be transmitted through a single cable. This significantly simplifies cabling infrastructure, especially in space-constrained and complex industrial environments.


Why PROFINET Compliance Matters?

PROFINET compliance ensures that Single Pair Ethernet (SPE) solutions meet the strict industrial requirements for performance, reliability, and interoperability.
Driven by PROFIBUS & PROFINET International (PI), this integration allows SPE technology to be seamlessly incorporated into existing PROFINET networks, providing standardized and reliable communication while advancing the vision of Industry 4.0 and smarter industrial automation.


What makes CTi's PROFINET-compliant SPE cables different?

CTi's PROFINET-compliant SPE cables are specifically engineered to exceed standard SPE performance.
Key advantages include:
  •        Enhanced flame retardancy for improved safety
  •        Heat shock resistance without cracking
  •        Tensile strength up to 50N
  •        Designed for high-flex and dynamic applications
These features ensure reliable performance even under the most demanding industrial conditions.


What SPE product solutions does CTi offer?

CTi provides a comprehensive SPE cable portfolio, including:
•        Standard SPE cables
•        High-flex SPE cables for dynamic applications
•        M8/M12 hybrid cable solutions

These options are ideal for use in industrial robots, moving machinery, and advanced automation systems.
