Our first order of 25 km of FBG-optimized sensing fiber for a high-rise structural monitoring project in Dubai showed minor cladding diameter variance slightly outside the ±0.7 µm tolerance on approximately 3 km of one reel. We raised the issue with the technical team immediately. They acknowledged the non-conformance, issued a replacement reel within 9 business days, and provided updated IEC 60793-1 inspection records for full traceability. The resolution process was professional. The replacement fiber performed correctly. Rating reflects the initial issue, not the service response.
