  • This Thing’s a Lifesaver for Fiber Work!
Style: 100-120KM VFL
Okay, so I snagged this Zenithra 100mW Visual Fault Locator for some fiber optic work, and holy cow, it’s awesome! I’m not gonna lie, I was a bit skeptical about the 100-120KM range claim, but this little red light pen seriously delivers. It lights up faults, breaks, and bends like nobody’s business, even on super long cables. Makes my job way easier when I’m trying to track down issues in the field. The build is legit—feels tough with its stainless steel head and aluminum body. I’ve dropped it a couple of times (oops), and it’s still going strong, no scratches or dents. Plus, the dust-proof design is clutch for working in less-than-ideal spots. It’s got a universal 2.5mm connector that plays nice with all my ST, SC, FC, and LC cables, so I don’t need to mess around with extra adapters (though they threw in a handy FC-to-LC one anyway). It runs on two AA batteries (you’ll need to grab those separately), and the battery life’s been solid so far. The kit also comes with a carrying pouch and lanyard, which is super convenient when I’m hauling my tools around. Honestly, this VFL has saved me so much time troubleshooting, and it’s just so easy to use. If you’re working with fiber optics, you need this in your toolbox. Totally worth the $89.99, especially with that 10% off coupon I snagged. Zenithra, you’ve got a fan in me! ... show more

  • Bright, but not 100km... More like 65km BARELY
Style: 100-120KM VFL
If you know anything about laser light, you'd know the shorter the wavelength the harder it is for light to travel. And red laser light like this, does not travel 100-120 km. It's impossible. With that being siad, it does travel ALOT further than your standard 30-35km laser. I was on a freeway project and was able to shoot laser to a node over 40 miles away. It was dim, but visible with all the lights off in the room. It could be a bit cheaper, especially when it claims to shoot distances it can't actually reach. But other than that, it's a decent little laser. easy to use, never used it for weeks without needed to replace the batteries so it's efficient too. ... show more

  • Review: Visual Fault Locator, 100mW 100-120KM Fiber Optic Cable Tester
Style: 100-120KM VFL
Every person who works with fiber optics needs this tool in their network toolchest. I used this Visual Fault Locator to test small runs at work and larger runs as well (over a mile long) and it worked perfectly. The light comes through nice and bright and makes it easy to help troubleshoot fiber optic lines. Overall, very happy with this and can't recommend it enough. ... show more
