The basic principle is to send a signal down the cable and then study the reflected signal back. If the cable is sound without any intermittent faults or arc faults then the reflected signal will be exactly the same as the sent signal. If the cable is not sound, the reflected signal will be 'altered'. By studying the exact location of the alteration, a time domain reflectometer can help identify the exact location of the fault.
A more technical, academically reviewed paper with diagrams on how the reflected signal is changed can be found at http://livewiretest.com/analysis-of-spread-spectrum-time-domain-reflectometry-for-wire-fault-location

What is an explanation of what an OTDR represents?
An Optical Time Domain Reflectometer (OTDR) is a device used to characterize the performance of an optical fiber by measuring the amount of light that is reflected back along the fiber. This reflection data is used to locate faults or losses in the fiber, such as breaks or bends. OTDRs are commonly used in the telecommunications industry to troubleshoot and maintain optical networks.
What is domain test?
A domain test is to test if a domain is available. It tells you if the domain is available and if it is how much it costs.
What tool can you use to test a fiber optic cable?

What is principle the Murray Loop Test?
A Murray Loop Test is used to locate faults in networks of cables such as three-phase services, groups of underground cables, etc. It works by using the principle equation on which the Wheatstone bridge is based: when the galvanometer is in a null condition, R1/R3=R2/R4. The location of a cable fault within a network can be found by using a process of elimination: good connections are identified and are then excluded from further iterations of the Murray Loop Test.
How can one test out a domain for their website?
You can test a domain by going to the website or asking other people to view your website. There are also companies that will test the website for you, for a fee.

How do you test the 11KV HT cables?
The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.
