Spans to Splices: On the Transition of Fiber Optic Cable into Substations

As the boundaries between utility and telecommunications markets continue to blur amid ongoing grid modernization efforts, it is essential to understand the integration points between the various solutions, network stages, and grid components involved. One key example is the transition of fiber optic cable into substations, as cable and substations are traditionally considered distinct segments with dedicated expertise. This session will bridge that gap by combining insights from cable, hardware, substation, and connectivity perspectives. Multiple cable transition scenarios will be examined to demonstrate the range of possibilities, and the relevant cable types will be discussed, including:

• Optical Ground Wire (OPGW)

• All-Dielectric Self-Supporting (ADSS)

• Underground Micro Cable



Each stage of the transition will be explored in detail, including cable attachment to end structures, routing of cable, splicing to transition cable (as applicable), routing into the substation and splice hut, and termination to substation assets. Supporting materials to be covered will include cable attachment accessories, splice enclosures, slack storage solutions, patch panels, splice cassettes, field-installable connectors, and splicing technologies. By drawing on knowledge from these different product types and market segments, this overview will equip attendees with the high-level knowledge needed to seamlessly integrate fiber optic cables into substations.
