In the optical world we call it OTDR (optical time domain reflectometry). What an imaginative bunch we are /s.
You can get a tiny box to do it, to find fiber breaks and bad splices.
- Prcmaker 5y agoThere's also OFDR now, frequency based. My understanding of it is pretty hand-wavey, but it's a lot more sensitive.
- canadianfella 5y ago> pretty hand-wavey What do you mean?
- shadowgovt 5y ago"hand-wavey" refers to (in this context) an understanding that is missing a lot of detail. The term refers to the notion that if someone asks you to explain a specific piece of the theory, you'd have to respond with "enhhhhh...." and a wave of your hand
- Prcmaker 5y agoYep, pretty much exactly this. I understand it enough to use it as a tool and do some rudimentary troubleshooting, but to explain how it works would require some waving of the hands to fill in my knowledge gaps.
