NF-919 Optical Power Meter, Light Source and VFL

Measure optical power, supply a test light and inspect suitable fibre paths with one rechargeable three-function fibre tester.

✅ Check optical power at the connection - The power-meter function presents readings in selectable optical-power units.

✅ Compare against a reference level - REF mode supports relative loss checks within a correctly arranged test.

✅ Provide a compatible test source - Switchable 1310 nm and 1550 nm light-source settings support appropriate fibre tests.

✅ Use a visible-light inspection aid - The 650 nm red-light function offers steady or flashing illumination for suitable visual checks.

Bring the test source and reading together

Fibre work can involve checking a received level, comparing loss or visually inspecting an accessible path. The NF-919 groups the power meter, source and visible-light functions so the tool can support those separate checks.

Select the wavelength, units and reference appropriate to the test and use compatible connectors. Keep optical outputs away from eyes and follow fibre-test procedures; a visible indication does not replace the measurements needed to assess the complete link.
