Fibre Visual Fault Locator Pen

Bring a visible fault-checking tool to accessible optical fibre. This pen-style locator sends red test light into a matching connection to help reveal visible indications of breaks or other faults.

✅ Follow a visible indication during fault checking - Red light can help you identify a fault indication where the fibre is accessible for inspection.

✅ Use one locator with several listed connector types - The 2.5mm interface is intended for the specified FC, SC and ST connections.

✅ Keep it ready in a portable maintenance kit - The pen format, supplied bag and lanyard support carrying the tool between jobs.

A Visible Reference for Fibre Troubleshooting

The locator supplies test light rather than measuring the link's total optical loss. Use the visible indication as part of troubleshooting, with the connection and fibre handled according to the relevant maintenance procedure.

The listed port matches 2.5mm FC, SC and ST fittings. LC uses a 1.25mm ferrule, so plan and verify the correct adapter if the job uses LC rather than expecting a direct fit.
