Optical time domain reflectometers (OTDR) measure the elapsed time and intensity of light reflected along an optical fiber. They are useful tools for locating problems in an optical network as they ...

[android] has built up a fast edge pulse generator for time domain reflectometry (TDR). TDR is a neat technique which lets you measure cable lengths using electrical signals and can also be used ...

Single-mode Single-mode optical fibers will allow only one mode to propagate. The fiber has a very small core diameter of approximately 8 µm. It permits signal transmission at extremely high bandwidth ...
