Fiber Optic Test Equipment

Fiber optic test equipment verifies the installation quality and ongoing performance of fiber optic networks, covering everything from basic loss certification to detailed fault location. We stock a full range of fiber testing tools to support installation, certification, and troubleshooting work.

Choosing the Right Fiber Test Tool

Optical Loss Test Sets (OLTS) measure total end-to-end optical loss to certify a fiber link against industry loss budgets, making them the standard tool for installation certification. Optical Time Domain Reflectometers (OTDR) provide a detailed trace showing the location and loss of individual events along the fiber, making them the preferred tool for troubleshooting and fault location. Many technicians carry both tools, since certification and troubleshooting serve different purposes in a complete fiber test workflow.
