The viability of fiber optic cable communications is based on the fact that signals in a bundle of glass conductors can be passed faster, and over longer distances, than signals carried across bundles of copper cables. Since these conductors are created from spun glass, they are limited by their light weight and frangibility. Various electronic inspection tools are available that are optimized to allow technicians to examine these cable in place, without risking physical damage to the conductor caused by excessive movement .

Fiber optic microscopes are high power magnifying glass, that a service or spiral, to consider a fiber optic cable, rather than possible. These systems often create their own light, so that a technician, a driver closely with the chips, cracks or other defects that could affect the continuity of the signal and the speed of data transmitted to the driver identified. In general, these systems the target cable 200-1000 extension times, depending on quality and cost of the instrument.

digital device, continuity  source pitch recognition and an integrated fiber-optic cable to determine the effectiveness of the signal conductor. The process is to enable in this case, the unit continues to generate an internal signal from its end, an end to the end of the cable length. At that time, the test measures the gain of the unit signal cable amplitude (volume) signal, and detects the electrical resistance along its length in order to prove its effectiveness.

Optical power meter appear high intensity light to a length of fiber optic cable to measure the brightness of the candidate to an end and back. This specific unit fiber type. Copper wire or solid wire is not practical depth of technical tests, as the wiring metal base can be used on the signal strength.
