Review on Optical Ethernet Network Analyzer for Portable Disorder Testing, Measurement & Inspection by Jose Mcdaniel

If you're the type of person who likes to solve problems with wiring, telephone, antenna or anything else. This is a very handy pair of tools to add to your box. I just used them to trace a broken pair of wires in my home phone jacks and to trace an antenna wire from a pile of old antenna wires. For these projects alone, they have more than paid for themselves. Very easy to use and just make sure the wires you are working with are dead.
