Things You Should Know Before Choosing an OTDR

OTDR that is short for optical time domain reflectometry, is a fiber optic tester for the characterization of optical networks that support telecommunications. It can be used to measure loss, optical return loss (ORL) and optical distance on a fiber optic link. Besides, by providing pictorial trace signatures of the fibers under test, an OTDR can offer a graphical representation of the entire fiber optic link. However, there are so many OTDR brands in the market. Choosing the right OTDR for your application can be challenging. So this post is intended for giving some reminders when choosing an OTDR. Hope it may help you.


Why You Need an OTDR?

As we all know, fiber testing is an essential procedure to make sure that the network is optimized to deliver reliable and robust services without fault. So here are two reasons for why an OTDR is needed.

First, service providers and network operators want to insure that their investments into fiber networks are protected. Installers need to use OTDR performing bi-directional tests and providing accurate cable documentation to certify their work. Of course, OTDRs can be used for troubleshooting problems such as break locations due to dig-ups.

Second, premises fiber networks have tight loss budgets and less room for error. Therefore installers have to test the overall loss budget with a light source and power meter, which is a big task. While OTDR can easily pinpoint the causes for excess loss and verify that splices and connections are within appropriate tolerances, which saves lots of time. Besides, it is also the only way to know the exact location of a fault or a break.

What and Where Will You Test?

Before choosing a suitable OTDR, ask yourself the following two questions.

Loss, reflectance, splicing alignment and distance, which one are you going to test? Make sure the OTDR you choose can do what you want easily, quickly and accurately. If you need to make “live” test (like during a “hot cut”—splicing of fibers in a working cable), you need an OTDR that can do an active splice loss measurement in “real time”.

Where are you going to do testing? A good understanding of the applications of an OTDR will help you make the right choice for specific needs. For example, what kind of networks will you test? LAN (local area network), metro or long haul? What is the maximum distance you might have to test? 700 m, 25 km, 150 km?

What Should Be Focused on When Choosing an OTDR?

Many people may be familiar with OTDR but not know how to choose a real right one. Except for the quality that we must focus on, the following three factors also should be attached great importance to.

A Simplified and Task-focused User Interface

Maintaining fiber health is just as challenging and makes fast troubleshooting critical. Almost every OTDR on the market today is designed to cover carrier applications. As a result, many OTDR have very complex user interfaces which require the user to make sense numerous buttons and controls and navigate cumbersome multi-level menus. It’s bad for users improving operating efficiency. So a simplified and task-focused user interface test equipment is important.


Precision Fiber Channel Information

With the wide use of short patch fibers and various types of fiber connectors, details on network link—loss, connector and reflectance—are critical to ensuring performance. However, OTDR with an attenuation dead zone of more than 3m are no longer applicable for testing data center fiber. But when problems arise, an OTDR with precision fiber channel information can help users with various skill levels efficiently perform troubleshooting and accelerate network recovery.


Effective Planning and Documentation

As data centers grow and change, it’s challenging to ensure all fibers are installed with certificated quality. Therefore, integrated project management capabilities with cable-by-cable granularity can save time and planning effort. An OTDR with built-in project management capability that allows users plan day-to-day activities without using a personal computer or laptop.


Selecting a proper OTDR to test your network not only can strengthen its reliability, but also improve the efficiency of the testing job as well as documenting the quality of work. Therefore, before selecting an OTDR, considering the applications and specific needs of your testing work will ensure that it is suited for your applications. FS.COM provides various types of OTDR with different wavelengths such as 850 nm, 1310 nm, 1550 nm and 1625 nm. You can find one that best suits for your network.

Fiber Optic Tester–An Important Tool for Your Network Installation

Fiber optic testing is necessary in optical installations. Accurate testing result can’t be got without high quality fiber optic testers. And there are various kinds of fiber testers available in the market. Today, this article mainly focuses on introducing several common types of fiber optic testers.


What Should Be tested?

When it comes to fiber optic installation and termination, fiber optic testers cannot be ignored. After the cables are installed and terminated, it’s time for testing. But what should be tested with fiber optic testers? Here are some common parameters which need to be tested.

Power Measurement

Power in a fiber optic system is like voltage in an electrical circuit. It’s important to have moderate power. Because too little power may not distinguish the signal from noise and too much power can cause errors too. So it’s important to measure power.

Loss Testing

Loss testing is the difference value between the power coupled into the cable at the transmitter end and what comes out at the receiver end. In fiber optic system, many things can result in loss such as dirt, connectors and breaks.

Optical Return Loss (ORL)

Optical return loss is the total accumulated light power reflected back to the source from the complete optical span. It includes the back scattering light from the fiber itself and the reflected light from all the joints as well as terminations. Generally, ORL is expressed in decibels (dB). And a high level of ORL will affect the performance of transmission systems.

In addition, some optical testers also can be used for troubleshooting.

Common Types of Fiber Optic Tester

Having known what should be tested in fiber optic testing. Now it’s time to know something about fiber optic testers. Generally, the common types of fiber optic test instruments are visual fault locator (VFL), OTDR (Optical Time Domain Reflectometry), optical power meter, optical multimeter, etc. Following is a brief introduction to the usual types of fiber optic tester.


OTDR comprising a laser source and an optical detector operates like radar. It generates short pulses of light and then samples the light scattered back by fiber segments and reflected by connections and other events. OTDR is the main piece of test equipment that is used to analyze a fiber optic link. In addition, as it is possible to calibrate the speed of the pulse as it passes down the fiber, the OTDR also can measure time.



VFL is an essential tool for testing cable continuity and locating visual faults. As is known to all, when light encounters a break or sharp bend, it scatters, and scattered light can be observed emerging from the cable. By emitting a laser beam of red light, the VFL can quickly illuminate fiber breaks, damaged connectors, detective splices and tight fiber bends. It even can locate the breaks in a short patch cord, which an OTDR cannot detect. Therefore, VFL is a helpful assistant to the dead zone of DTOR. And it also a basic maintenance tool for fiber network, LAN (Local Area Network) and telecommunication network system.


Optical Power Meter

Optical power meter is a device to measure the power of an optical signal. Its function is to display the incident power on the photodiode. When testing the signal, optical power meter is connected to different places. When testing transmitted power, t is connected directly to the optical transmitter’s output, but it will be connected to the fiber system while testing the received power. In a word, optical power meter is a the primary test instrument for fiber optic networks, as measuring optical signal power is a necessary task for any fiber technician.


Optical Multimeter

Optical multimeter, also called optical loss test set, is an instrument that measures several optical parameters such as optical power and wavelength. It adopts an optical laser source and an optical power meter into one handheld instrument, which makes it easy to measure the optical loss of optical fiber links, optical components and fiber networks.



In summary, choosing a good quality and high performance fiber optic tester not only can avoid unnecessary problems but also can improve your testing efficiency in fiber optic installation. FS.COM offers a wide range of cable testers and tools to meet any of your demand on copper or fiber installation, termination and troubleshooting. Welcome to visit for more information.

The Applications and Basic Settings of OTDR

OTDR refers to Optical Time-Domain Reflectometer, a test instrument that analyzes the light loss in an optical fiber and verify inline splices on concatenated fiber optic cables and locate faults. If you use fiber optic cables for network connectivity, you ought to know about the applications and basic setting of OTDR.

application of OTDR in life

  • OTDR can be used for return loss measurements, although quoted accuracy is not particularly high. It is very useful for measuring points loss on installed systems where it is used to find faults and measure point losses such as caused by splicing. However, to do this accurately is more complicated and time consuming than is commonly supposed. Since a measurement should be taken from both ends of the system and then averaged.
  • OTDR is useful for testing fiber optic cables. It can verify splice loss, measure length and find faults. It simply shows you where the cables are terminated and confirm the quality of the fibers, connections and splices. What’s more, OTDR trace could be also used for troubleshooting, since it can show where breaks are in fiber when trace is compared to installation documentation.
  • OTDR is also widely used for optical cable maintenance and construction. Because it can evaluate the fiber cable length, measure optical transmission and connection attenuation, as well as detect the faulty location of the fiber links.
  • In addition to fiber characterization, OTDR can also be used for sensing chemicals and gases. Because certain substances cause changes to the light guiding properties of the fiber and those can be observed as changes in the measurement curve.

According to the contents above, we could learn that OTDR is a valuable fiber optic tester in many applications. However, if you use it in an improper way, it can be misleading and can lead to some unnecessary mistakes. So it is necessary to understand some basic settings when using OTDR. Using an OTDR is not very difficult, but it does require familiarity. Here are some tips on how to minimize the chance of making a costly mistake.

Basic Settings:

  • Fiber Type – first you should choose singlemode or multimode.
  • Wavelength – you usually start with 850 nm on multimode fiber and 1310 nm on singlemode, since the shorter wavelength has more backscatter so the trace will be less noisy.
  • Measurement Parameters – the typical parameters to be set are distance range, resolution, and pulse width.
  • Event Threshold – it determines how much loss or change will be tagged as an event.
  • Index of Refraction – it is the speed of light in the fiber. You can obtain this figure from the fiber manufacturer. In most cases, you can take it directly from a standard specific sheet.
  • Display Units – they are usually labeled in feet or meters.
  • Storage Memory – this should be cleared so a new figure can be saved or stored.
  • Dead Zone Jumper – you must connect this fiber which should be sufficiently long between the OTDR and the fiber under test. Sometimes you may also have to connect it at the far end of the cable.

OTDR is valuable test instruments that can illuminate problems in your optical fiber. Once you’re acquainted with what it is used for and learn some basic settings about it, you’ll be prepared to detect and eliminate your optical fiber events. It is an ideal test instrument applied to return loss measurement, fiber optic cables testing, optical cable maintenance and construction, as well as sensing chemicals and gases etc.

The Common Types of OTDR Test Equipments

OTDR is short for optical time-domain reflectometer, is an optoelectronic instrument used to characterize an optical fiber. It can offer you an overview of the whole system you test and can be used for estimating the fiber length and overall attenuation, including splice and mated-connector losses. It can also be used to locate faults, such as breaks, and to measure optical return loss. There are four types of OTDR, they are Full-feature OTDR, Hand-held OTDR, Fiber Break Locator, and RTU in RFTSs.

Full Feature OTDR

Full-feature OTDRs are traditional. They are feature-rich and usually larger, heavier, and less portable than either the hand-held OTDR or the fiber break locator. despite being characterized as large, their size and weight is only fraction of that of early generation OTDRs. Often a full feature OTDR has a main frame that can be fitted with multi-functioned plug-in units to perform many different fiber measurement tasks. Larger, color displays are common. The full-feature OTDR often has a greater measurement range than the other types of OTDR-like equipment. Often it is used in laboratories and in the field for difficult fiber measurements. Most full-feature OTDRs are powered from an AC source and or battery source.

Handheld OTDR and Fiber break locator

Handheld (formerly mini) OTDRs and fiber break locators are designed to troubleshoot fiber networks in a field-type environment often using battery power. The two types of instruments cover the spectrum of approaches to fiber optic plant taken by the communications providers. Handheld OTDR is more cheaper, more easy to use and light weight than full feature OTDR, sophisticated OTDRs to collect field data and perform rudimentary data analysis upon. They may be less feature rich than full feature OTDRs. Often they can be used in conjunction with PC based software to perform easy data collection with the hand-held OTDR and sophisticated data analysis with the PC-based software. 

The hand-held OTDRs are commonly used to measure fiber links and locate fiber breaks, points of high loss, points of high reflectance, link end-to-end loss, and Optical Return Loss (ORL) for the link. Fiber break locators are intended to be low cost instruments specifically designed to locate the position of a catastrophic fiber event, e.g., point of high reflectance, or high loss. The fiber break locator is an opto-electronic tape measure that is designed to measure only distance to catastrophic fiber events.

In general, hand-held OTDRs and fiber break locators are lighter and smaller, simpler to operate, and more likely to operate using battery power than full-feature OTDRs. The intent is for hand-held OTDRs and fiber break locators to be inexpensive enough for optical technicians to be equipped with one as part of their standard tool kit.

Remote Test Unit (RTU)

An RFTS enables fiber physical plant to be automatically tested from a central location. a central computer is used to control the operation of OTDR-like test components located at key points in the fiber network. These test components will scan the fiber to locate problems. If a problem is found, its location is noted and appropriate Operations Systems (OSs) are notified to begin the repair process. The RFTS can also provide direct access to a corporate database that contains a historical repository for the OTDR fiber traces and any other fiber records for the physical fiber plant.

Since OTDRs and OTDR-like equipment have many uses in the communications industry, their possible operating environment is varied, ranging from indoors to outdoors. Most often, however, these test sets are operated in controlled environments, accessing the fibers at their termination points on fiber distributing frames. Indoor environments include controlled environments such as in central offices (COs), equipment huts, or Controlled Environment Vaults (CEVs). Use in outside environments is rarer, but may include use in a manhole, aerial platform, open trench, or a splicing van.

FiberStore supply all kinds of OTDRs, our OTDRs are available with a variety of fiber types and wavelengths, including single mode fiber, multimode fiber, 1310nm, 1550 nm, 1625 nm, etc.. And we also supply OTDRs of famous brands, such as JDSU MTS series, EXFO FTB series, YOKOGAWA AQ series and so on. OEM portable and handheld OTDRs (manufactured by FiberStore) are also available. What’s more, we also offer many kinds of fiber optic tools. If you would like to know our OTDR price, please send your requirements to sales@fiberstore or visit our website.

FTTH Promote The Surge In Demand For Optical Network Testing

Testing is an important means to enhance network quality, network construction, an important means of operators. Test on the one hand, to ensure the consistency and stability of the business, at the same time can be effectively promoted the maturity of the industry.

Currently, the test is not only limited to test network equipment, more and more important for the business and user perception test. Therefore, testing techniques, testing tools developed laboratory environment to build all aspects of test quality assurance will affect the results of the entire test.

In the field of fiber optic communications, with China Mobile completed 100G network test now, “Broadband China” strategy forthcoming FTTH being the country vigorously. Fiber optic communication testing methods and techniques are changed with the change of network.

FTTH test can be roughly divided into the construction, maintenance, fault diagnosis phases. FTTH three wavelengths (1310nm, 1490 nm and 1550 nm) loss during the construction phase, the test focus. The optical splitter in a PON will bring a larger loss (such as a 1:32 optical splitter loss will be greater than 15dB), not only makes the light generating loss downlink, the uplink of the light will produce substantially the same loss. Splitter implementation techniques vary, making each optical path loss may exist differences, in order to strictly limit each optical path loss within the budget is a challenge.

Optical return loss is one of the difficulties of the current test. Optical return loss is not only a loss of energy, but also lead to the originator laser instability. Recommendations based on the ITU-TG.983 and G.984 series, optical return loss values should be in both directions. PON-based FTTH OTDR put forward new demands, requires not only support the 1490nm wavelength testing, but also with penetrating optical splitter. In addition, FTTH network transmission distance is shorter, but the introduction of the high loss of optical splitter requirements OTDR dynamic range wide enough selection of shorter OTDR dead; joints more requirements, high linearity.

In large-scale FTTH deployment phase, testing will be very heavy instrument automation has become one of the factors to be considered. FiberStore’s FOT-930 test instrument developed for this demand, the user simply one-button operation can be completed in the 10s three wavelengths (1310nm, 1490 nm and 1550 nm) bi-directional loss, optical return loss and fiber length test and automatically store test results.

Activation and maintenance, fault diagnosis stage, the most commonly used test instruments PON power meter. EPON or GPON system using time division multiple access technology, OLT and ONT need to activate in order to work, PON power meter has to trigger tests optical power capacity and support meter needs different optimization. FTTH construction early will also face business opened the challenges, many links need to manually construction service activation, as well as the opening of a long cycle, poor customer perception. Troubleshooting link, the failure rate and the declaration of DSL-more than twice the proportion of regional centers for processing, the door-to-door high.

FiberStore, EXFO, JDSU and other enterprises to provide FTTH is simple, fast, and a variety of intelligent solutions, provide strong support for FTTH construction.
