Probably not a splitter. It gets very confused shooting past it (both our cheap China & the demo Veex). On Fri, Sep 29, 2023 at 3:24 PM Trey Scarborough wrote: > Could be a bad splice, but if it is a splitter it could just be an > artifact of that. It all depends on the type of splitter you are

Re: [AFMUG] dumb OTDR question

Could be a bad splice, but if it is a splitter it could just be an artifact of that. It all depends on the type of splitter you are using and what wavelength the OTDR is. It also depends what is on the other ends of the splitter. If that is a splitter with nothing spliced to one of the ends you

Re: [AFMUG] dumb OTDR question

Absolutely. Probably just a bad splice. Mark > On Sep 28, 2023, at 9:32 AM, Adam Moffett wrote: > > Can you have return loss (i.e. reflections) on bad fusion splices? > > Attached trace is a splitter showing return loss. It's supposed to be fusion > spliced, not connectorized. There are

Re: [AFMUG] dumb OTDR question

Yes, and depending on the length of the fiber and the conditions on the other end, you can have a return loss effect causing a splice to appear to have negative loss. Called a “gainer“. But this trace looks like a bad splice to me. From: Adam Moffett Sent: Thursday, September 28, 2023 7:

Re: [AFMUG] dumb OTDR question

When we found issues in our fiber, it has always been bad bends. We have Sumitomo splicers and they've all been flawless so far. Just our experience. Our OTDR is cheap china junk - it can't actually detect the splices ~90% of the time. Veex demo units caught every single splice. On Thu, Sep 28
