2PCS Visual Fault Locator 50mW, VFL Tester Kit 50KM Range - Includes Single Mode 9/125um FC Male to LC Female Adapter and Red Light Pen for Fiber Optic Cable Network Testing

The tool performs its function effectively and is well-designed. Its exceptionally bright light makes it convenient for testing fiber optic cables.

Bought this laser in April. Worked great was used daily and kept in my reflection vest pocket, so it was put to work. Other end of fiber strand would shine bright so easy to see. Unfortunately after enough uses the orange cap broke off and exposed the silver cap where you connect your fiber to which ended up breaking next and became very lose. Now laser will not shine through unless you wiggle it and play around while connecting your fiber to the laser to find the “sweet spot”.Update: managed to buy a replacement plastic white tip and silver cap for the top of the laser from KELUSHI. Fixed the problem working back at 100%

Does the job well.

I have used this on many occasions and it worked perfectly. I wish it had a larger storage to be able to store the adapter and a fiber patch cable with the unit. Even if it was an addition item to purchase with this.

I use these for work. Very bright light. Makes it much easier to locate a fiber cable.

super bright! better than the one they give us. you can see it through the caps way better. worth the money for the time it will save me from looking for my dim ass light

As a network technician, I've found the Visual Fault Locator 30KM to be an invaluable addition to my toolkit. Its ability to detect fiber optic faults such as breaks, poor connections, and bends is impressive, emitting a strong 650nm red light that makes identifying issues straightforward. I had read the reviews and some reviews reported issues with the LC adapter not fitting securely on the unit, luckily, I have not had this issue.

do not use in data centers but good for the every now and then fault finding
