Optical reflectometers (OTDR)

General information

Optical reflectometers (English name: OTDR) allow automatic measurements of the main parameters of fiber optic communication lines: determination of the length of the optical line and distances to points of inhomogeneities of the optical fiber (welding, switching points, etc.), calculation of attenuation in the line, the amount of return loss and the amount of the reflected signal, visual determination of FOCL damage and much more.

Tehencom company supplies a large number of optical reflectometers (OTDR) both portable and laboratory. You can buy a reflectometer from us at a good price from a warehouse in Kyiv. We deliver orders throughout Ukraine. If you need technical advice or assistance in comparing the characteristics of reflectometers, you can contact our technical specialist: contacts (consultation is free). We also carry out training in the theory and practice of reflectometric measurements and provide optical fiber measurement services (singlemode and multimode).

Comparison table

This page has a lot of information about different series of modern reflectometers. Each series has a short description and a photo. The table below shows the same reflectometers, but not by series, but by models. At the same time, for each model, the main technical characteristics are indicated (dynamic range, operating wavelengths, dead zone, etc.).

All models of optical reflectometers sorted in the table as they increase dynamic range. If the dynamic range is the same, then the cheaper models are placed first.

Notes:

¹ Dynamic Range – the best value is indicated, which the reflectometer can provide at the maximum duration of the probing pulses. The more dynamic range, the better. For more information about probing pulses, see here.

² Event Dead Zone (EDZ) – the best value is indicated, which the reflectometer can provide with the minimum duration of the probing pulses. The dead zone determines the ability of the reflectometer to distinguish closely spaced events. The smaller the dead zone, the better.

³ Operating range on a real line - the guaranteed length of the fiber optic line is indicated, which can be measured at the maximum duration of the probing pulses. At the same time, a margin of dynamic range is provided so that the end of the trace is 5 dB above the noise level. Please note that for PON networks, the range is much shorter and depends not only on the dynamic range of the reflectometer, but also on other parameters.

All series of optical reflectometers

The table below presents a wide range of new optical reflectometers for solving any modern problems. If you need detailed pricing information or technical advice on choosing the best OTDR for your application, just call us or write to us at E-mail and we will be happy to answer your questions.

Comparison of the best models by price level

When choosing an optical reflectometer, the first question that you may be interested in is the cost of the device. The cost of reflectometers depends on many parameters, for example: the number of wavelengths, dynamic range, dead zone, correctness of the reflectogram (minimum noise and absence of phantom events), the ability to connect a microscope, the convenience and security of the case, etc.

If, when choosing a reflectometer, you will focus only on its price, then you may not be satisfied with its other parameters. On the contrary, think about the value of the device, based on its characteristics and capabilities. good device allows you to quickly and efficiently perform work, and this saves time, nerves and money.

In the price range up to $1,000 the most simple USB reflectometers without a screen are offered, capable of measuring the parameters of short lines (up to 10 km) at two wavelengths (1310 nm and 1550 nm). Near about $1,000 we offer the only economy series Grandway FHO3000, made in a compact instrument case with a touch screen. Economy reflectometers Grandway FHO3000 allow you to comfortably work with single-mode fibers with a length of several tens of kilometers.

In the price range from $1,000 to $4,000 there are most models of purely Chinese reflectometers, with different wavelengths, auxiliary options (built-in power meter, transmission, etc.), the ability to connect a microscope to check the quality of connectors, and other useful features. A typical representative of this price range is a series of reflectometers Grandway FHO5000.

In the range over $4,000 high-quality, accurate and functional series of world famous companies such as EXFO and Anritsu are produced. Devices of this price range are ideal for building and maintaining networks with a large number of subscribers (from several thousand to tens of thousands), PON networks, as well as for optical networks of industrial enterprises. typical representative: EXFO MaxTester 700C. Optical reflectometers of this price segment have all the features that you may need when performing any kind of work. At the same time, the devices themselves are very convenient and reliable, and the accuracy and stability of measurements meet the highest standards. To better understand the difference between the features and quality of models under $4,000 and models over $4,000, check out this comparison: Selecting an OTDR for PONs.

Please note that all optical reflectometers can be equipped with additional useful options that significantly expand the functionality of the device, but at the same time increase its cost.

Discontinued models

Manufacturers of measuring equipment regularly develop and launch new models of optical reflectometers with enhanced capabilities and improved characteristics. After some time, after the start of sales of new models, old models and series out of production. A complete list of discontinued reflectometers, with an indication of the proposed replacement, you can see here: optical reflectometers discontinued.

Basic theory on optical fiber reflectometry

Measuring the parameters of optical fibers is a rather complicated topic. Specialists who perform such measurements need to understand both the reflectometer itself (instrument modes and settings) and the theory of signal transmission over optical fiber, be able to distinguish good reflectogram events from bad ones, and know how to correct defective sections of the optical line.

Here are collected the main articles and documents on the theory of reflectometric measurements, which will help you understand this issue and improve your professional level. For complex and incomprehensible moments, write to us by E-mail or call - we will be happy to advise.
