No setup or interpretation required – just place in front of the fiber end face or port and a light and tone indicate an active fiber. This pocket-sized tool tests single-mode, multimode UPC and APC patch cords and ports using a “non-contact” detector. The FIBERLERT-125, detects for the presence of 850 nm to 1625 nm optical light.

Pretty nice tool to have in your tool belt as a network admin. Simply detects light on a fiber strand. No more, no less. You'll need a more feature rich (expensive) tool to really troubleshoot fiber issues, but if you just need to make sure there is light making it through your fiber, this works great.

This saves a lot of time and frustration. I connect fiber for a living.

this was a costly purchase but it does not have a light to trace fiber and that is what I was looking for.

Have this device for about a week now. I work in a complete fiber environment and this really saves time. If you work with a fiber heavy network, definitely should have in your tool kit. Its work the money.

Instructions could could be better, went to company website to view videos on usage.Needs a lanyard or wrist band not everyone wears a shirt with a pocket in which to put the device.Lightbeat feature is stupid and makes it confusing, when all it does is tell you that it’s about to power off.

This tester is simple to use and very helpful when all you need is to see if the fiber has a good connection.

When you have MM fiber, you can use your phone camera but under SM this tools is a “mustâ€

This is a very useful fibre optic detector, can save a lot of time checking cables, SPF modules etc,. Works well with no hassles or issues.

Das beste Tool ever, was ich bis jetzt gesehen und benutzt habe. Ich kann ohne teures Equipment SFP-Module auf Sendefunktion testen. Und wer schon mal Switche über eine Inhouse-Verkabelung geschaltet hat, weiß über die Vorteile Bescheid, wenn er am anderen Ende vom LWL-Patchpanel weiß auf welcher Faser das Signal ankommt.

Es macht was es soll. Teilweise muss man ein bisschen vor der Faser schwenken um das Signal zu finden, sonst ist es echt ne Arbeitserleichterung. Man muss nicht erst testen ob die Kabel verdreht sind, sondern sieht erstens ob überhaupt was ankommt und zweitens auf welcher Faser.
