We use a visual fault finder that is bright enough that you can hold it a few inches from a surface and see it blinking red light onto that surface.  No need to look at it.  I think it is made by Fluke Networks.  You can also see red light bleeding through the jacket of patch cables that are bad using this tool.

Hello all,

We have been organising our fiber and making sure it is properly labeled at each end.  We have been using a fiber fault finder, and that shines a bright laser light down the fiber and you can see it blinking on the other end.  This is great for locating fiber and finding breaks, but is not so great for the eyes.  Even though you try to avoid looking directly into the laser light coming from the other end, you always end up glancing at it quick.  Nevertheless, it hurts my eyes and I am not very fond of using the tool this way.  

Has anyone seen a tool that uses a really bright light (maybe an LED) so the other end of the fiber can be found?  Otherwise, I am going to start wearing UV glasses.

Thanks,


Jeremy

Hi Jeremy,

 

You should be able to use any light source, but a specific tool that shines down the middle of the strand is best. We've used flash lights before, but it's just a little bit more difficult to aim down the center of the strand without something holding it still.

 

A quick google found that Miller makes a pocket fault finder that uses LED and has 5 lumens of power, model CCT-2.

 

Good luck,

From the specs of this device, I assume they are using this on multimode fiber.

 

I built one of these many years ago using a pocket flashlight with an ST coupler mounted on the lens.  The barrel fits a standard LED.  Works very well on multimode, but singlemode requires a dim room to locate the light.  Total cost around $6.

 

I later built one with the guts of a $2.99 pocket laser that is better on singlemode J

 

Just wanting to encourage the creative hardware hackers out there.

I just leave the cap on the fiber. Not as cool as the lightsaber, but does the job.
