IEEE P2893/D2, Nov 2022

IEEE P2893/D2, Nov 2022 is an inactive IEEE approved draft standard focused on the Flexible Optical Service Unit (OSUFlex) of Optical Transport Network (OTN) in power systems. It addresses how optical transport can support power-sector communications with flexible service units suited to demanding operational environments. For utilities and engineering teams working with photonics and electrooptics, this draft is relevant because it helps frame interoperability, performance expectations, and implementation consistency for OTN-based infrastructure.

Overview of IEEE P2893/D2, Nov 2022

IEEE P2893/D2, Nov 2022 provides technical direction for OSUFlex within an Optical Transport Network context, with emphasis on use in power systems. The standard is intended to support structured handling of optical services that may need adaptable bandwidth or service mapping in utility communications networks. As an approved draft, it is useful for understanding the proposed requirements and design approach behind flexible optical transport functions, especially where reliable data carriage is important to system operations and monitoring.

Typical use cases

This draft is most relevant for power-system communication networks that depend on optical transport links, including substation interconnects, control and monitoring channels, and utility backbone communications. It may also be used by engineers evaluating OSUFlex behavior in OTN equipment, integration planning, or network design for photonics-based infrastructure. IEEE P2893/D2, Nov 2022 can help guide discussions around how flexible optical service units fit into operational networks that need predictable transport characteristics.

Why it matters

For organizations designing or procuring optical transport solutions for power applications, IEEE P2893/D2, Nov 2022 supports clearer technical alignment and more consistent implementation choices. Using a defined draft standard can reduce ambiguity during specification, testing, and system integration, which is especially valuable in networks tied to critical utility operations. It also helps teams compare equipment and document requirements more consistently, lowering the risk of mismatched expectations across vendors, projects, and engineering workflows.
