What is OTDr?
Optical Reflector Time Domain (OTDR) is used in fibers optics to measure time and intensity of light reflected on optical fiber. More on the thing is used as a device to eliminate problems to find errors, buckles and bends in optical fiber cables with respect to the identification of light loss. Loss of light is particularly important in optical fiber cables as it can disrupt data transmission. OTDR can detect such loss of light and determine problems with problems, which makes it easier. The faster they are identified and solved, the less your optical network will suffer from data transfer problems. The user connects cables with optical fiber in the same way that two drivers connect the batteries with connecting cables and then reset the OTDR settings for any parameters used in a particular test. Typical OTDr can take anywhere from ten seconds to three minutes.
OTDr uses the light scattering in the optical fiber to make its measurement. OTDR releases a high -performance pulse that behindIt reaches the thread and bounces back. What is coming back is measured, factor in time and distance, and the result is "problem places" that emit and can be focused on repair. In general, data is in the form of wool, with problems clearly visible as aberrations in the wave.
Some OTDR systems are equipped with PC connection capabilities, so the data recorded during testing can be downloaded to a computer for analysis and storage. Naturally specific software applications are naturally available for such analysis.
Of course, OTDr is not perfect. Critics charge that they can bring inaccurate results if two problems are very close to each other or if the pulse has a long travel of LENGTH. Experts also apply for training to interpret the data correctly. Another factor is the relatively high price for equipment that could only be used sparingly. However, supporters face the ability to determine and solve the points of loss of the worldThe pressure is worth the price, both for the OTDR and the training needed for operation and the correct understanding of the data recorded by the OTDr.
