Features and Benefits

Fully Autonomous Inspection

with an All-in-One Solution


Automate your Inspection Workflow with the Press of a Button


With FiberChek, technicians get a complete fiber-inspection solution in the palm of their hand. There is no need to connect to other devices to inspect, test, or store. All of those capabilities, and more, are already built into the FiberChek probe.

Contaminated connectors are the #1 cause for troubleshooting in optical networks. Maintaining best practices with an Inspect Before You Connect workflow is essential, but without the right tools, it is difficult and time consuming. FiberChek eliminates these challenges by fully automating every detail of the inspection workflow.
