About This Item

Legal Notices*

IEEE P802.3cq/D3.1, Sept 2019 is an inactive IEEE draft standard for Ethernet amendment work focused on Maintenance #13 for Power over Ethernet over 2 pairs. It is relevant to communication and networking systems where power delivery and data transfer need to coexist on twisted-pair cabling. As a draft technical document, IEEE P802.3cq/D3.1, Sept 2019 helps define requirements that support consistent design, evaluation, and implementation of two-pair PoE solutions.

Overview of IEEE P802.3cq/D3.1, Sept 2019

This draft belongs to the IEEE 802.3 Ethernet family and addresses an amendment related to Power over Ethernet over 2 pairs. In practical terms, it provides a technical basis for maintaining and refining Ethernet power-delivery behavior while preserving compatibility with networking equipment and cabling practices. For engineers and procurement teams, the document is useful when reviewing specification details, design constraints, and compliance expectations tied to two-pair PoE implementations.

Typical use cases

IEEE P802.3cq/D3.1, Sept 2019 may be used when developing or assessing Ethernet equipment that carries both power and data over two pairs, such as network endpoints, connected devices, and supporting infrastructure. It is especially relevant for design teams working on wired communication hardware, integrators validating power delivery behavior, and organizations comparing draft requirements for product planning or technical review. The standard is also useful when documenting compatibility and implementation intent for PoE-related systems.

Why it matters

This draft matters because Power over Ethernet features often depend on clear, repeatable requirements for interoperability, testing, and design control. IEEE P802.3cq/D3.1, Sept 2019 helps reduce ambiguity when evaluating two-pair PoE behavior, which can support more consistent product development and procurement decisions. Using a defined technical reference can also lower integration risk, improve comparison between implementations, and make compliance review more straightforward for networking hardware programs.
