Review on 🔍 KELUSHI Visual Fault Locator Fiber Optic Cable Tester VFL for FC, SC, ST & LC Adapter - High-Performance Aluminium Alloy, 30km Range by Peter Bates

I guess. This can damage the retina. !Buy the bag right away as it comes with additional features for connection. I used a Klien camo lined zippered pouch previously ordered from Revain. Fits perfectly. I'm not sure if this device can troubleshoot. It's so bright it breaks through the breaks in the fiber. I think the best would be to identify individual lines. A kind of continuity tester. I used it to identify circuits from MDF to multiple IDF. Worked great! Couldn't believe how bright it was.
