Aligning with National Strategies: How SPE Enables Network Convergence and Upgrade

In line with national strategic initiatives, Single-Pair Ethernet (SPE) technology empowers industrial Control-Network-Compute Integration.

In accordance with the Action Plan for Integrated Empowerment of Industrial Internet and Artificial Intelligence issued by the Ministry of Industry and Information Technology in early 2026, SPE, together with 5G-A and TSN, has been identified as a key enabler for integrated industrial networking.

Zhaolong Interconnect has adopted a forward-looking layout and established a comprehensive SPE cable product portfolio, whose reliable performance has been verified across multiple high-end manufacturing sectors.

Building a Multi-Scenario SPE Product Matrix to Bridge the IIoT Last Mile

Driven by technological innovation, the company has developed a multi-application SPE product matrix, delivering integrated connectivity solutions for the Industrial Internet of Things (IIoT) spanning from the cloud to edge sensors.

01 Process Automation: APL-SPE Cables Realize Kilometric Data-Power Convergence

For process automation applications, Zhaolong's APL-SPE cables comply with the IEEE 802.3cg standard. Equipped with 18 AWG high-purity copper conductors, they ensure stable data transmission at 10 Mbps over a distance of up to 1,000 meters.

Integrated with Power over Data Line (PoDL) technology, a single pair of wires delivers both data and power up to 57.5 W simultaneously. The aluminum foil and tinned copper braided dual-layer shielding effectively mitigates electromagnetic interference (EMI), drastically simplifying on-site wiring. These cables have been successfully implemented in the process automation systems of renowned domestic pharmaceutical enterprises.
