Ordered 5 × 500 m LSZH OFNR OM2 spools for a campus network upgrade in Melbourne. On arrival, two spools had spool-length labels reading 480 m rather than the ordered 500 m. I raised this with the support team immediately. They responded within 6 hours, confirmed it was a labeling error, and verified via their production OTDR records that actual fiber length was 501 m and 499 m respectively. Replacement labels and corrected test reports were emailed within 24 hours. Optical performance — attenuation at 850 nm at 3.2 dB/km — was fully within spec. Issue was minor and handled professionally; no impact on the installation.
