Our cloud data center needed urgent interconnect upgrades. We piloted these optics instead of waiting for OEM inventory. Optical sensitivity is phenomenal, allowing us to hit 80km targets without inline amplifiers. Prometheus and Grafana integration via custom SNMP scripts was completely effortless. Truly reliable engineering for production environments.
