General information
Optical time domain reflectometers (OTDRs) allow for automated measurements of key fiber optic communication line parameters: determining the length of an optical line and the distance to fiber discontinuities (splices, connectors), calculating line attenuation, reflective signal magnitude, and much more.
The principle of operation of an optical reflectometer – how it is designed and how it works
Best models
This table contains the best models of optical time domain reflectometers with the status of Top sales or Expert's choice. Such models have a high price / capability ratio, so they should be paid attention first of all. The table is interactive, any column can be sorted in ascending or descending order.

Additional equipment
In addition to the main list of optical time domain reflectometers presented above, the following additional series are produced: the inexpensive Grandway FHO3000, the universal Grandway FHO5000, for monitoring active fibers EXFO Nova Fiber RTU-2 and the modular analyzer Anritsu MT1000A. Also used for servicing fiber optic communication lines are: optical loss testers, fiber inspection probes, optical spectrum analyzers, modular test platforms, fiber optic fusion splicers and other telecommunications equipment.
Manufacturers of measuring equipment regularly develop and launch new models of optical time domain reflectometers with expanded capabilities and improved performance. Some time after the start of sales of new models, old models and series are discontinued. A complete list of discontinued optical time domain reflectometers, including proposed replacements, can be found here: discontinued optical time domain reflectometers.

Basic theory
Buying an inexpensive and high-quality optical time domain reflectometer is not always easy. When choosing a model, in addition to the standard parameters: wavelengths, dynamic range, event dead zone, attenuation dead zone, it is necessary to take into account additional characteristics and capabilities of the reflectometer: pulse width, sampling points, working with live fiber, possibility and ease of programming, built-in digital interfaces, a set of additional functions, operating temperature range, quality and durability of the device, the reputation of the manufacturer, the professionalism and reliability of the supplier, the availability of a service center, warranty period and much more. In addition, you may need technical advice on the types of reflectometers produced: for short lines, for PON, for longhaul and universal.
Measuring optical fiber parameters is a fairly complex topic. Specialists performing such measurements must understand both the reflectometer itself (its modes and settings) and the theory of signal transmission over fiber optics, be able to distinguish good from bad reflectogram events, and know how to correct defective sections of the optical line.
The next section Documentation contains useful information on the theory and practice of using optical time domain reflectometers, which will help you understand this issue and improve your professional level. For complex and unclear issues, write to us by e-mail or call, we will be happy to advise.
