fiber optic testing suite
BarnDr. combines every essential tool for live event fiber testing into a single 2RU rack unit. Technicians plug their fiber cables directly into the appropriate port — for inspection (microscope), tracing (VFL), or measurement (optical power meter) — getting everything they need instantly.
This accessibility drastically cuts down on troubleshooting time and, more importantly, reinforces best practices by making it easy to inspect and clean fiber before connecting. By preventing infrastructure contamination, the BarnDr. delivers substantial maintenance cost savings over the long run.
Comes with both 2.5mm and 1.25mm mating adaptors to accommodate ST, SC, FC and LC fiber connectors.
Large, easy to use focus ring to quickly sharpen the image in seconds or less.
High quality 3.5” LCD display for easy viewing.
X/Y position is locked to a fixed position with set screws or included thumb screws for easy adjustment.



Good Green lights show good power levels, yellow lights for low but measurable signal, and red for very low power levels. No need to think in dB units if you don’t want to.
The meter readout is also shown on a high-vis OLED screen showing precision power levels in several units. Absolute units shown as decibels with reference to one milliwatt(dBm) and actual milliwatts(mW).
Hold the button to zero the meter to a reference level, just like zeroing a scale.
Extremely simple use, just press the button to turn on the laser. Extremely handy to ID fiber lines or to cause breaks and tight bends visible in patch cables to glow.
At 2mW, the laser is powerful enough to get light to anywhere in your venue, but still safe and legal to use.
Connect to the power meter with a known good patch cable, then zero out the power meter. Now you can test any cable between the two ST connectors on the Heliac-R and take reliable measurements of the cable’s condition.
Cleaning OpticalCON connectors is crucial because even microscopic dust and oils on the ferrule end-face cause significant signal loss and poor performance. Mating dirty connectors can also permanently scratch the fiber, leading to costly repairs and network failure.
Cleaning optical connectors are vital because microscopic contaminants like dust and oil on the ferrule end-face cause significant light signal loss, or even permanent damage on the polished surface, leading to poor network performance. Inspection with a fiber microscope is essential to verify cleanliness before mating, ensuring the core is clear of debris. This prevents permanent scratches that cause costly damage, ensuring reliable, high-speed data transmission.
