Initial batch had labeling inconsistency — issue fully resolved
Ordered 15 reels of OM1 62.5/125µm fiber for a building backbone project. The fiber performance itself met TIA-568 and IEC 60793 attenuation specs on testing. However, three reels had mismatched batch numbers on the reel labels versus the test report documentation, which flagged during our QC check. I reported this to the supplier and received corrected documentation within 24 hours along with a formal explanation. The technical specs were never in question — purely an administrative issue. They handled it professionally and the project completed on schedule. Cautiously optimistic for future orders.
