Maintenance & Repair
Scheduled inspections, splice closure resealing, and rapid repair keep a fiber plant performing years after the original build. Preventive maintenance and damage response for live and dark fiber networks across Central Texas.
A Fiber Plant Degrades Long Before It Fails
Fiber networks are built to last decades, but they are not maintenance-free. Splice closures lose gasket integrity from UV exposure and thermal cycling. Aerial strand sags and shifts. Buried conduit gets struck by third-party excavation long before anyone notices a service impact. Left unmonitored, these small failures compound into rising loss, intermittent faults, and eventually a live outage that costs far more to fix under emergency pressure than it would have on a scheduled visit.
CoreSync treats maintenance as an extension of the same fusion, testing, and documentation standards we build to. A scheduled inspection walks the plant against your as-builts, checks every closure we can access, and localizes any drift in loss budget with OTDR before it becomes a customer-facing problem. When damage does happen — storm, dig-up, or age — we scope the real repair instead of a patch and re-certify the segment when it is done.
Central Texas brings its own maintenance pressure: summer heat cycles that stress aerial closures, spring storm season that takes down strand and poles, and a steady pace of utility and road construction that puts buried plant at risk. A maintenance program built around those local conditions catches problems your original installer's warranty window never covers.

Preventive Care and Damage Response
Scheduled Plant Inspections
Recurring walk-outs and closure checks on a schedule you set — pole-to-pole aerial review, vault and handhole condition checks, and splice-tray audits before small issues become outages.
Enclosure Inspection & Resealing
Gel and heat-shrink closures degrade with UV exposure, thermal cycling, and re-entry wear. We inspect gasket integrity and re-seal any closure that no longer holds a proper environmental barrier.
Damage Localization & Assessment
OTDR-based fault localization pinpoints a break or high-loss event to within meters before a crew is dispatched, cutting truck rolls and guesswork out of the repair.
Cable & Conduit Repair
Full-scope repair of damaged cable jacket, crushed conduit, and compromised innerduct — re-splicing, re-routing, and re-housing as the damage requires, not just a patch.
Storm & Weather Restoration
Aerial strand down, pole damage, and wind-driven debris are a routine part of the Texas storm season. We mobilize to reattach, re-splice, and re-certify affected spans.
Underground Dig-Up & Re-Splice
Third-party dig damage to direct-buried or conduit-run fiber gets located, exposed, repaired, and re-spliced with the same fusion and OTDR standards as new-build work.
From Fault Report to Re-Certified Segment
Assess & Locate
For scheduled work we walk the plant against your as-builts; for a fault we run OTDR from both ends to localize the event before a truck is ever dispatched.
Scope the Repair
We confirm whether the fix is a re-seal, a re-splice, a cable segment replacement, or a conduit/innerduct repair — and what access, traffic control, or utility locates the work requires.
Repair or Restore
Crews execute the fix to the same fusion, closure, and bend-radius standards as new construction — no shortcuts because it is a repair instead of a build.
Re-Test & Document
Every repaired segment is re-certified with bi-directional OTDR and the as-built record is updated, so your documentation reflects the plant as it actually exists today.
Maintenance for Every Stage of Plant Life
Maintenance is not a one-time service call — it is the ongoing work that keeps a fiber investment performing for its full service life. CoreSync supports plants we built and plants built by others, on a recurring schedule or a single damage call.
Need a fault localized and repaired the same standard as new construction? Pair maintenance with our OTDR testing and certification so every repair leaves you with updated, acceptance-ready documentation.
Frequently Asked Questions
What does a scheduled fiber maintenance visit include?
A scheduled visit covers aerial and underground plant walk-outs against your as-builts, splice closure and gasket inspection, vault and handhole condition checks, and a splice-tray audit — flagging anything trending toward failure before it causes an outage.
How quickly can you respond to a fiber cut or damage report?
For active outages we treat the call as emergency dispatch — see our 24/7 emergency response. For non-service-affecting damage found during inspection or reported by a third party, we typically schedule repair within days, prioritized by risk to the live network.
Do you repair conduit and innerduct, or only the fiber itself?
Both. A repair often needs crushed conduit cleared or replaced and innerduct re-routed before the fiber itself can be re-spliced, so we scope and execute the full repair rather than just the cable segment.
Why does a splice closure need resealing years after installation?
Gel and heat-shrink seals degrade over time from UV exposure, thermal cycling, and re-entry for prior maintenance. A compromised seal lets moisture into the closure, which corrodes splices and raises loss long before it causes an outright failure — regular inspection catches this early.
Will a repair update our as-built documentation?
Yes. Every repair is re-tested with bi-directional OTDR and the splice matrix and as-built records are updated to reflect the plant as it exists after the fix, not just as it was originally built.
