Around cable

Consider the primary functions of reflectometers, such as automatic detection, searching for crossed pairs, and identifying 'floating' defects.

Critical options for reflectometers: Why is this important, and how do you use it?

The noise filtering function - how to use it, when it helps and when it interferes with measurements. An important parameter is the velocity of propagation (VoP) - how it affects the measurement accuracy and how it can be determined experimentally if its value is unknown.

How to compare OTDRs from different manufacturers? What is more critical: resolution capability or sensitivity? How to determine the actual range of a device?

What determines the accuracy and range of defect detection? What is better: short/long or single/multi-pulses? Case: one reflectometer, but different types of cables.

The reflectometer measures the reflection of a signal. This method for cable damage detection complements all the others we've previously discussed and, in some cases, gives more accurate results, especially when locating wire entanglements or breaks and looking for non-persistent faults. Furthermore, it allows one to clearly identify several individual problems when they interfere with each other, as well as determine the range of each one of them.

Applications, details, and features.

When servicing metal cable lines, measuring bridges are most commonly used. They are accurate in a wide range of measured values, with compensation of extraneous influences, and inexpensive.
