From my experience, it is only short distance such as a fiber enclosure. Or pig tail inside the node. **Q: Is it supposed to come with an adapter for sc and st? mine came with no adapters. how to connect st to the meter?** A: I did not receive one either. I can not find one made for it. But it was pretty accurate compared to my old light meter with blue and green. **Q: Is there a digital version of the user guide? My unit didn't come with instructions.** A: Not sure. The great part is it only does basically 3 things. play with the buttons for a couple minutes you know more than the manual. 1) cable fault locator (red laser/on off). 2) function key sets db reading (check light level). toggle to RG45 you can check for faults on ethernet. That’s it, good luck **Q: What about lc interface ? i work with lc connections most** A: Lc is can't.It suit for SC/FC/ST. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Slight Expensive but Accuracy high *by M***O on 29 May 2026* Very good Optical power meter.
