Case Studies
U.S. Enterprise Campus Renovation
A nationwide corporation used GAO Tek TDR handheld testers to locate open and mistermination points within copper backbone wiring. Fault localization reduced troubleshooting time by 50% and minimized service disruption.
U.S. Telecom Node Upgrade
A telecom provider deployed GAO Tek OTDR units to audit fiber links at central offices. High-resolution OTDR traces revealed splice losses and reflectance issues before system activation, enabling proactive resolution.
Canadian Educational Campus Fiber Audit
A Canadian university engaged GAO Tek OTDR systems for campus-wide fiber validation. The process identified fiber degradation zones and helped create a long-term maintenance schedule to ensure consistent uptime.
