A clear starting point
Fiber Fault Investigation
Locate the likely fault, explain the evidence and agree on a repair or next test.
A fault-finding visit with a defined stopping point
A good fit
A damaged fiber, intermittent link, loss of light or an unexplained link failure between equipment rooms or buildings.
What you receive
The checks performed, connector and link observations, measured loss where appropriate, repair findings and remaining uncertainties. We agree the evidence needed to accept the result.
How we scope it
Share the symptom, affected route, connector/fiber information if known, access conditions and service impact. Investigation and repair can be separate approved stages.
FryAVSI can tone, test optical loss and fusion-splice fiber. An OTDR or other specialist testing is arranged when the scope requires it. A splice estimate does not replace an end-to-end loss test.
Tell us what stopped working
Useful starting details include the affected locations, when the problem began and any recent construction or equipment changes. A link light, alarm message or photograph of the damage helps narrow the first visit.
- Is one device, one building or the entire site affected?
- Did the fault follow repatching, excavation or a hardware change?
- Can the team reach both fiber ends and intermediate enclosures?
- Are there existing test records or spare fibers?
For an active outage, call 330-575-6134 to discuss availability. Dispatch and restoration timing depend on the fault and site conditions.
Separate the possible causes
Confirm the affected link → Check patching and optics → Test the fiber path → Agree on the repair
We review the connector arrangement, compatible optics and accessible cable condition before assuming the installed fiber needs replacement. Appropriate optical measurements can help distinguish a damaged path from an equipment or configuration issue.
OTDR testing can help locate events along a fiber, but it requires the right setup and interpretation. It is a separately scoped resource when the investigation needs it.
Restore service and preserve the findings
The repair may involve a patch lead, termination, protected fusion splice or replacement cable section. Available slack, route access and materials affect the options.
Closeout records the fault found, work performed, test evidence and operational checks. If a temporary repair gets the business connected first, its limitations and follow-up work remain explicit.
