Utility & Energy Companies
Electric cooperatives, TDUs, pipeline operators, and grid managers depend on fiber that performs inside energized environments. CoreSync brings the safety discipline, technical precision, and documentation standards that utility-grade fiber infrastructure demands.
Fiber That Runs the Grid Can't Afford to Be Rebuilt
Utility fiber is operational technology, not information technology. The fiber running through a transmission substation or alongside a distribution corridor isn't carrying office traffic — it's carrying SCADA telemetry, protective relay communications, and distribution automation signals that keep the grid stable. A splice that degrades over three years costs far more than the splice itself; it costs the grid event or outage investigation that follows.
The work environment adds another layer of complexity. Fiber inside substations and along ROW corridors sits in proximity to energized infrastructure. Every CoreSync crew entering a utility work zone operates under your safety management system — not a generalized construction safety plan adapted on the fly. We coordinate with your line clearance team, follow your LOTO procedures, and work within the proximity limits your engineering standards define before a single splice tray opens.
NERC CIP-governed fiber assets and USDA-funded rural electric programs both carry documentation requirements that outlast the project itself. CoreSync delivers as-built records formatted for GIS integration and infrastructure management systems — not loose PDFs that become unreadable before the next maintenance cycle. When a storm takes down OPGW or compromises splice cases on a distribution corridor, we respond 24/7 with the same precision and documentation discipline we bring to scheduled utility work.

- OT-grade OTDR testing to your acceptance criteria
- GIS-ready as-built documentation for compliance records
Built for the Utility Field Environment
Transmission Corridor Fiber
Fiber splicing and closure work along high-voltage transmission and distribution corridors — coordinated with your line crews and executed under your safety rules of engagement.
SCADA & Substation Connectivity
Communications fiber inside substations and between control points, spliced and tested to the loss budgets your SCADA and distribution automation platforms require.
OPGW & ADSS Cable Support
Optical Ground Wire and All-Dielectric Self-Supporting cable splicing using the closure types and fiber entry methods your engineering standards specify — not generic commercial methods.
Utility Safety Compliance
Work conducted under your safety protocols — LOTO coordination, energized-line proximity limits, required PPE, and clearance documentation before any crew enters a right-of-way.
OT-Grade Testing & Acceptance
Bi-directional OTDR testing and insertion-loss verification documented to your operational technology acceptance criteria, not general IT network standards.
GIS-Ready As-Built Records
Splice matrices, tray maps, and trace files formatted for integration into your GIS or infrastructure management system — suitable for NERC CIP documentation requirements.
Safety First, Then Precision, Then Documentation
Pre-Job Safety Review
We review your work order, clearance procedures, and site hazards before mobilization. No CoreSync crew enters a utility ROW without understanding the energized infrastructure surrounding the work zone.
Utility-Compliant Field Execution
Splicing performed under your safety management system — proper PPE, line clearance coordination, and closure methods matched to your cable and closure engineering standards.
Test to OT Standards
Every fiber path verified with bi-directional OTDR before handoff. Out-of-spec splices corrected on the spot. SCADA-critical paths receive additional loss-budget confirmation.
Documentation for Operations
As-built records delivered in your format — splice matrices, closures mapped to structure numbers, and OTDR trace files ready for your GIS, document management, or NERC CIP records.
From Co-ops to Grid-Scale Transmission
Whether you're a rural electric cooperative running distribution automation fiber across a service territory, a TDU managing communications fiber on a 345kV transmission corridor, or a pipeline operator maintaining ROW fiber alongside a gas transmission system, the operational stakes make splice quality and documentation non-negotiable.

Frequently Asked Questions
Does CoreSync have experience working around energized electrical infrastructure?
Yes. CoreSync crews operate under utility safety management systems, including LOTO coordination, energized-line proximity limits, and required PPE. We follow your clearance procedures before any crew enters a right-of-way adjacent to live electrical infrastructure — this is a non-negotiable precondition of any utility engagement.
Can CoreSync splice OPGW on transmission lines?
Yes. We perform OPGW fusion splicing using the closure types and fiber entry methods your engineering standards specify. OPGW work is coordinated through your transmission line crews and conducted only after proper clearances are in place.
Do you work with rural electric cooperatives?
Yes. CoreSync supports rural electric cooperatives managing distribution automation fiber, SCADA connectivity, and member broadband programs — including work under USDA ReConnect or USDA Rural Development funding that requires documented, audit-ready as-builts.
Can CoreSync respond to storm damage on utility fiber?
Yes. We provide emergency restoration for storm-damaged utility fiber — whether OPGW downed by ice or wind loading, ADSS cable broken from galloping conductors, or splice cases compromised by flooding. We dispatch 24/7 with the same documentation standards applied to scheduled builds.
Do you provide documentation suitable for NERC CIP or utility compliance records?
Yes. Our as-built deliverables include splice matrices, closure-to-structure mapping, and OTDR trace files in formats suitable for GIS integration and infrastructure management systems. For NERC CIP-governed assets, we coordinate with your compliance team on record format and retention requirements before the job begins.
