Can it test for both multi and single mode fiber? If i use it below 10KM cable, will it harm the cable?

I use it with SM cable - yellow I use it with MM cable - aqua & orange (san)

Can i bring it for travel/ on the plane?

If you are going to be testing Fiber lines, yes. I don't know why you wouldn't be able to take it in a carry on. I mean unless you plan on shining anyone, they'd be just as upset if it were a regular flashlight. The emitter isn't as strong as some of those pointer laser lights, still, probably not good to shine someone.

Reliable and Cost-Effective Fiber Testing Tool

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.

Easy to lose part/adapters as there is no place to store them in light pouch

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.

super bright

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 lightFollow up: 9/15/25 - after using it, i find the battery compartment is hard to keep tight. It loosens up and the light goes out.
