Types of Fiber Optic Testers

Fiber optic testers are essential for testing and maintaining the performance of fiber optic networks. Different types of fiber optic testers are available to meet the needs of different applications. The following section summarizes the most common types of fiber optic testers available on the market.

Loss/OTDR (Optical Time Domain Reflectometer): OTDRs measure events along optical fibers by sending a pulse of laser light, then measuring how long it takes each pulse to travel down and back along the cable and analyzing how much of that light has been lost or reflected back up the line.

Power Meters: Power meters measure a wide range of power signals in an optical link, allowing users to troubleshoot problems with splices and other issues without having to view each connector individually.

Optical Light Sources: Optical light sources are used to test transceivers for continuity or send data for transmission over a link. A light source emits a continuous beam or pulses that test for signal quality, losses due to dispersion, reflections and other factors affecting network performance.

Analog Optical Testers: Analog optical testers are designed to test analog links between devices such as transceivers and amplifiers by measuring both analog data rates and visual indicators. These devices can detect issues, such as jitter, that require more sophisticated instrumentation than traditional link tester models provide.

Optical Time Domain Reflectometer (OTDR)

An Optical Time Domain Reflectometer (OTDR) is the most commonly used optical testing instrument in the industry and is commonly used to detect faults in long fiber optic cable lengths. It works by sending short pulses down the cable and then measuring the delay time, loss, or reflection for each event along its length at each end of the line.

A OTDR allows a technician to quickly and accurately diagnose a wide range of issues including broken fibers, failed connections, poor splices, poor cable integrity, poor continuity or weak signals. This type of test also provides detailed information on each event including location, length and magnitude allowing technicians to accurately pinpoint and resolve any issue quickly.

Additionally it can be used to measure attenuation losses in hundreds of meters with a single measurement. All these features make OTDRs essential tools for those who maintain fiber networks.

Optical Power Meter (OPM)

An Optical Power Meter (OPM) measures optical power at various wavelengths and is used in telecommunication systems to accurately record, track, and analyze optical power levels. The device is also helpful in ensuring that the system employs appropriate values of attenuation or gain which can be adjusted as required.

Different types of Optical Power Meters are available depending on your requirements. They range from digital OPMs that provide fine resolution measurements to units with a real-time automatic wavelength tuning feature for rapid measurements on any fiber types. Also, others provide the user with backlit LCD displays providing a clear view of measurement results in low-light conditions. Precision OPMs provide users with precise readouts, while other OPMs are designed to allow simple point and shoot measurements without precise readings or any external calibration source.

Regardless of the application and needs, all OPMs measure the optical power in dBm (decibel milliwatts), and many come with built-in laser sources allowing direct measurements without needing additional instrumentation. A wide selection of testing capabilities are provided by various manufactures including power monitoring over various fiber types such as multimode, single-mode, SMF-28e+, G657A2/A1 etc., wavelengths from 850 nm to 1625 nm spectrums along with average power measurement over different time scales giving insight into reachability status in the network. Many modern models also feature automated spectral analysis functions providing end users with detailed spectral analysis even over high-spectral dynamic range signals like PON networks.

Visual Fault Locator (VFL)

A Visual Fault Locator (VFL) is a device used to detect and examine breaks, bends, and discontinuities in optical fiber. It produces short pulses of laser light and can be used to identify breaks in the core of the fiber, which presents an opaque light barrier.

VFLs are available in various types ranging from visible red LED sources up to recent LED multimode laser sources, which provide the user with both visible red light (for finding faults) and near infrared (NIR) for trace locations and end-to-end testing purposes. The higher power output VFLs offer improved visibility for singlemode fiber inspection particularly in fouled spaces such as patch panels or inside optical closures.

Light Source (LS)

Light Sources (LS) are used to send a light from a transmitter device or an optical cable into the receiver device or another optical cable. The basic function of Light Sources is to inject single or multimode light into an optical network. This can be done with the help of Laser light sources, LED light sources, or even an obscured laser source like a flashlight. The selection of which type of Light Source is best depends on your application, testing objectives and the overall budget available.

For singlemode fiber testing, laser LS offers greater details on faults in long distance networks due to its narrow spectral wavelength. LED light sources can also be used but the results would not provide as much accuracy when compared to using Laser-based light sources for singlemode fiber testing across long distances. For multimode networks, LED LS offers greater flexibility as it emits a relatively broad incidental wavelength thereby allowing it to support both 50/125µm and 62.5/125µm fiberoptic cables simultaneously.

Apart from this, there are other features like power meter timer which measure power and timing waste parameters including Pulse Width Modulation (PWM). Furthermore, power meter functions such as averaging out the Power Spectral Density (PSD) for finding maximum loss peaks in real time should also be considered before making your choice for the best Light Source tester that fits your specific application needs in 2023.

Factors to Consider When Choosing a Fiber Optic Tester

It is important to consider certain factors before investing in a fiber optic tester. These considerations will ensure the tool is capable of meeting the requirements of your specific job. Here are some of the features that you may want to look for in a fiber optic tester:

  • Test Data Storage: The capacity to store accurately measured test data over long-term usage can be helpful in analyzing and troubleshooting problems.
  • Software Interface: Look for an easy-to-navigate interface that will allow you to access its full complement of features without any hassle. A good software interface should also include troubleshooting tools and help functions.
  • Connectors Support: It is important that the tester comes equipped with support for all connector types, as different connectors in many cases have different test procedure requirements.
  • Additional Technologies: Depending on the type of task, additional technologies like optical talk sets, power meters, visual fault locators should be included with a tester so you can perform multiple tasks without needing separate equipment.
  • Probe Types and Accessories: Also take into account whether specific probes or accessories are required for certain tests, such as FiberViewer or tone generators which are used quite frequently when dealing with cables project management activities or locating faults within cables.

Purpose of the Tester

A fiber optic tester analyzes, tests and maintains optical networks. It helps technicians troubleshoot network problems by providing complete diagnostic data on the performance of the network and its link elements.

The tester provides quick and accurate fault location, which reduces time and money spent on rectifying errors. The purpose of a fiber optic tester is to accurately measure optical power output from a source, detect light along the entire length of a cable, identify broken fibers, losses at splices or connectors, measure insertion loss for certification reasons, determine distance-to-fault for locating breaks in long runs of fiber optic cable, check for proper splicing methods used in the installation process and inspect for cleanliness of connectors.

Type of Fiber Network

Before researching and buying a fiber optic tester, it helps to understand what type of fiber network your project requires. Different types of networks have different testing procedures, so picking the right testing tool is important. Some common types of fiber networks are:

-Multi-mode Fiber: Multi-mode fiber networks use an LED to transmit light which is then converted back into electrical signals at the receiving end. These types of networks are commonly used in short distance applications such as within a building, or campus environment.

-Single Mode Fiber: Single mode fiber networks use lasers instead of LEDs to transmit information over a much longer distance as compared to multi-mode. Single mode networks are used for most long haul applications such as long distance telephone communication or cable TV distribution.

-Gigabit Ethernet: Gigabit Ethernet works by combining traditional Ethernet frames with optical technologies so that data can be transmitted faster over the same physical mediums like single mode or multi-mode blades. Typically gigabit ethernet is used for high speed backbone networks between computers on a larger scale network like corporate offices or university campuses.

Frequency Range

The frequency range of an optical fiber tester is an important feature to consider when making a purchase, as it determines the maximum and minimum frequencies to which the tester can be tuned. Choosing a tester with a wide range of frequencies allows you to measure parameters over a wider band and minimize ambient interference.

Most professional-grade fiber optic testers offer frequency ranges from 4 Hz up to 12.75 GHz, but these may vary from model to model. Generally speaking, the wider the frequency range, the more signals it will be able to detect and accurately measure.

Additionally, make sure that your chosen fiber optic tester has an adjustable high-definition LCD display so you can accurately read its results.
