We needed inspection tools that grade to IEC 61300-3-35 consistently across our sites. This range delivers repeatable pass/fail results, so acceptance no longer depends on who is holding the probe. Documentation supports our audits well.
Stable fiber optic cable light sources for insertion loss testing paired with a power meter — laser and LED. Request a quote.
A fiber optic cable light source injects a stable, known optical signal into a cable so a power meter at the far end can measure insertion loss and confirm continuity. Source stability is everything: if the launched power drifts during a measurement, the calculated loss is wrong. A dependable cable light source is therefore the quiet foundation of every accurate loss and continuity test on a cable run.
Aevumix supplies fiber optic cable light sources in laser and LED formats for single-mode and multimode testing. Laser sources deliver the narrow, stable output single-mode certification needs; LED sources suit multimode loss testing. Multi-wavelength models cover the common test windows, and each source is matched to our power meters so the wavelengths align for accurate, repeatable dB results across a cable build.
Because the right source depends on your fiber type, wavelengths and whether you certify or troubleshoot, we help you specify the correct unit. Send your wavelengths and fiber type and we will recommend a cable light source and provide a quote.

A loss test is only as good as the source stability. These light sources hold their output with low drift, so our loss readings are the link, not the instrument. Consistent performance across every unit we have tested.

The stable light source gives me a reference that does not wander between readings, so my loss numbers hold up. The tone output helps identify fibers in a bundle too. Handy, reliable, and built for the field.

Incandescent and thermal lamps cannot be used in fiber optic systems. Learn why, what a fiber source must do, and the special case of the LED.
The light-emitting sources used in fiber optics are LEDs, laser diodes, and VCSELs. Learn how each works, the coherent vs incoherent distinction, and which fiber each suits.
How to use an optical power meter to measure fiber power and loss: cleaning, wavelength matching, setting the reference, reading dBm vs dB, and avoiding mistakes.
It launches a stable, known signal into a fiber cable so a power meter measures insertion loss and verifies continuity. Source stability directly determines measurement accuracy.
Single-mode certification generally uses a laser; multimode testing often uses an LED. We supply both — tell us your fiber type and standard.
Yes. For accurate loss testing the source wavelengths must match the meter's calibration. We supply matched sets or confirm compatibility with your meter.
Yes. Many sources output several wavelengths so one unit covers your test windows. Send your required wavelengths for a recommendation.
