About This Item
IEEE P1138/D7, 2021 is an IEEE draft standard focused on testing and performance for optical ground wire (OPGW) used on electric utility power lines. It addresses the technical needs of combining electrical grounding with fiber-optic communication in one line component. For engineers, utilities, and procurement teams, the document helps frame how OPGW should be evaluated for reliable operation, installation suitability, and performance consistency in power and photonics applications.
IEEE P1138/D7, 2021 overview
This draft standard is intended to guide the testing and performance expectations for OPGW, a specialized cable system used in overhead utility networks. IEEE P1138/D7, 2021 sits at the intersection of power transmission and optical communications, where cable design must support both grounding function and fiber-optic service. The document is relevant to technical review, product qualification, and comparison of candidate OPGW constructions against a common set of requirements and test practices.
Typical use cases
IEEE P1138/D7, 2021 is typically used when specifying or evaluating OPGW for transmission corridors that need both lightning protection and communication capability. It is useful during utility network upgrades, line design work, and equipment procurement for overhead power systems. The standard may also support laboratory testing, acceptance review, and supplier coordination for cable assemblies that must perform under electrical, mechanical, and environmental conditions common to electric utility infrastructure.
Why this standard matters
For OPGW projects, clear testing and performance criteria help reduce ambiguity across design, procurement, and field deployment. IEEE P1138/D7, 2021 supports more consistent evaluation of cable behavior before installation, which can lower the risk of compatibility issues or underperformance in service. In practice, that matters because OPGW must meet both utility grounding expectations and optical communication needs, making consistency and traceable technical requirements especially important.
