Frequently Asked Questions 

1. How do OTDRs work?
   OTDR testers contain a laser source that sends out a pulse of light at a specific wavelength. As the pulse moves through the optical fiber under test, the OTDR detects the light that reflects or refracts back down the fibre toward the device. By analysing the returning light from the pulse the instrument can determine the type, location, and loss value of events in the cable. Displaying this on the screen of the tester allows users to diagnose issues from the optical return loss and reflectance.
2. How do I choose the right OTDR?
   Many factors impact the type of OTDR which is right for your application. Firstly, the type of networks under test and the fiber types should be considered. Whether you opt for a singlemode or multimode OTDR will depend on the type of fibers you will be testing and the type of measurements you will be making are also important when choosing a device. The dimensions and weight of the tester are also important to consider so that you have the right balance of function and portability. Other factors that may make a difference are the battery life, size of the display, and storage capacity for results. Whether the device is compatible with intelligent optical link mapping is another thing to consider. 
3. What's the difference between an OTDR and IOLM?
   IOLM or intelligent optical link mapping is a way of enhancing your OTDR testing through automation. An IOLM application simplifies complex trace analysis by automatically defining the testing parameters and interpreting the multiple traces for you. Many of the OTDRs we stock are compatible with intelligent optical link mapping. 
4. What wavelengths do OTDRs operate at, and why does it matter?
   Many OTDRs work at ordinary wavelengths (for example 1310nm and 1550nm) that are well suited for typical single-mode testing. For FTTx or passive optical network(PON), more wavelengths, such as 1490 nm, 1625 nm, and so on, are indispensable for operation. Appropriate wavelength selection enables accurate fault and reflectance/attenuation detection at the fiber link.
5. What is dynamic range in an OTDR, and how does it affect testing?
   Dynamic range is the OTDR’s capacity to see weak reflections at greater distances. With a higher dynamic range (i.e., 35–45 dB) you can verify longer fiber runs and find small problems with more certainty, which is critical for metro and long-haul applications.
6. What are event and attenuation dead zones, and why are they important?
   Event dead zones determine how close two events can be and be separated by detection. Attenuation dead zones influence the ability to measure gradual signal loss. Short dead zones OTDRs will be in demand in high-density environments such as data centers where the connectors and splices can be very closely spaced to each other.
7. Can OTDRs be used for FTTx or PON testing?
   Yes. FTTx/PON dedicated OTDRs have a very high dynamic range and superior filtering to characterize events even through the splitters. Such modules typically work at 1490 or 1625 nm wavelengths and can feature dedicated PON test modes for precise fault location.
8. Are handheld or portable OTDRs available for field testing?
   Absolutely. Deployment ready, portable, battery operated, touchscreen, and rugged OTDRs are available in a handful of field ready, lightweight, handheld formats that are easy to transport in the field or to a telecom closet, or even out on the strand or in an outdoor enclosure.
9. Do OTDRs include other functions like VFLs, power meters, or inspection scopes?
   A few OTDRs have the advantage of an all-in-one unit with VFL’s, optical power meters and video inspection probes. These functionalities allow for fiber testing to be simplified while minimizing the need for additional test tools.
10. Can OTDR test results be exported or saved for reporting?
    Yes. Your typical OTDR will have a USB or SD card for saving your trace results and PDFs, or export the information to the cloud and share the file with a fellow tech. Some of them also include an automatic report feature that is used for documentation or turning in other project documentation.
11. Why rent an OTDR?
    Giving you the flexibility you need, renting an OTDR allows you to access the right equipment at a fraction of the cost of buying, with no delays or downtime. With our rental solutions, you can use top-of-the-range OTDRs without any of the upfront costs. Plus, if your testing and measurement needs change it’s easy to change your rental, too.
12. Why buy used OTDRs?
    You can access top-quality OTDRs at stunningly low prices by buying certified pre-owned instruments. All fully tested and calibrated by our experts, our pre-owned OTDRs are on sale for a fraction of the price of new devices. Buying pre-owned is one of the most cost-effective solutions for all your optical fiber testing needs.
