Single-pair Ethernet interface
In plain English
What does Single-pair Ethernet interface mean?
A single-pair Ethernet interface uses its specified physical-layer arrangement over one conductor pair.
A simple example
A compatible industrial node can use the selected PHY and connector for its single-pair link.
What the drawings help you do
Label the specific single-pair Ethernet variant and identify both cable ends. One pair describes the conductor arrangement, not a universal speed, distance or connector. Show any power-over-data arrangement separately and only where the selected equipment supports it.
- Single pair
- One pair of conductors used by the selected link.
- Physical layer
- The electrical and transmission arrangement of a communication link.
Before using this reference
- State the selected single-pair physical-layer variant.
- Reference the supported connector and cable design.
- Identify any power-delivery function separately.
Do all single-pair Ethernet devices connect interchangeably?
No. The physical-layer variant, connector, cable and supported operating conditions must match. A common conductor count does not establish interoperability.

A distinction that matters
The single-pair label does not make every Ethernet variant or connector interchangeable.
