ULTIMODE OR-20-S3S5-iSMV is a device designed for measuring and diagnosing optical fibre connections. It combines the functions of: OTDR, optical power meter, light source and visual fault locator.
The device generates pulses at 1310 nm and 1550 nm. This enables full diagnostics of the optical path for fibre attenuation, splices, connectors, as well as events like fibre bending and cable bending or breakage. Dynamics of 20 dB enables inspection of connections up to a length of several tens of kilometers.
The special features of ULTIMODE OR-20-S3S5-iSMV include small size and comfort of use. 3.5-inch touch screen and intuitive and simple interface allow for easy navigation and quick measurement. For this reason, the device is perfect for installers who have no experience with this type of equipment.
The results of the measurements performed can be automatically stored in the device's memory (about 30 MB of built-in memory available, allowing 300-500 measurements to be stored) or on a U-disc memory stick (USB-C flash drive – for example, in the case of a 16 GB flash drive, the number of possible measurements to be stored reaches as much as 250,000). The results easily and quickly can be downloaded to a PC via a USB-C cable (the device is visible as a portable memory stick), and then used to generate simple or advanced measurement reports in pdf/xls format with the OTDR Assistant software.
In addition to the ability to perform a standard reflectometric measurement at two wavelengths and generate a graph of events in the optical path (reflectogram), the ULTIMODE OR-20-S3S5-iSMV features iOLA function. This option is especially recommended for less experienced installers, it enables automatic execution of a series of measurements without defining the parameters of the measurement pulse, measurement range, etc. The result is presented in a clear graphical form in the form of a link with marked events such as joints, splices, bends, etc.
A very useful option is the ability to enable the "Pass/Fail " verification when performing measurements. This makes it possible to check the connections against preset boundary conditions, i.e.: attenuation of the entire connection and attenuation and/or reflectance of individual events. The verification takes place on the device itself and can be transferred to the measurement report. It is therefore possible to generate a pdf report with the "Pass " indication, i.e. to acknowledge that the desired expectations have been met.

OTDR measurements require the launch fibre. It eliminates the so-called OTDR dead zone and correctly measures the parameters of the first connector in the system. ULTIMODE launch fibres with a length of 150 m are excellent for measurements of short (up to several kilometers) connections. Versions with SC/APC connector matching the ULTIMODE OR-20-S3S5-iSMV reflectometer and connectors are available: SC/APC L58510, SC/UPC L58512, LC/UPC L58514. These launch fibres have a practical, convenient-to-use housing and the ability to protect the connectors when the components are not in use. Depending on the type of connectors encountered in the system, one or more launch fibres should be provided. If you want to properly measure the connector at the end of a fibre optic link, then it is necessary to use the launch fibre.
Dirty OTDR connector is one of the most common causes of problems in performing reflectometry measurements. Using tools to clean the OTDR socket and the plug of the runner plugged into it is crucial for a properly performed measurement and the life of the connector itself. A dirty connector compromises the dynamics of the device and generates high signal reflection. Failure to clean can lead to damage to the OTDR socket which is one of the more common failures in this type of device. Use good practices – clean the connectors! We recommend a proven solution from the renowned Japanese company NTT Nanoclean E3 L59161.
ULTIMODE OR-20-S3S5-iSMV is equipped with 2 lasers operating at 1310 nm and 1550 nm. This makes it possible to perform a comprehensive measurement of the optical path. 1310 nm is the basic wavelength at which measurements are made, it allows highlighting problems with fibre positioning (higher attenuation of connectors and splices), while the 1550 nm wavelength can, in turn, reveal problems with cable or fibre bending. It is thus worthwhile to perform measurements for both wavelengths.
This function allows the installer to save time by automatically measuring at 2 wavelengths with different measurement parameters. The results are analyzed by the OTDR and then presented in a graphical form that everyone can understand. This option can be used, among others, by novice installers and those who want to perform a quick but comprehensive measurement with verification that the attenuation of the entire link is within the specified limits.
Presenting the parameters of individual events in tabular form for both wavelengths and graphical visualization of the fiber optic link allows for quick analysis and conclusions in the event of problems. In the example presented here, the problem is a poorly made weld.

The "Pass/Fail" analysis option is an extremely important feature for those who develop their systems according to predetermined rules (e.g., multi-family housing – optical path attenuation less than 1.2 dB) or for those who, after the service has been performed, want to submit a measurement report containing clear information on whether the system meets the specified requirements. The OTDR analyzes the attenuation of the entire measured section, taking into account all events (connectors, splices, etc.), and determines whether the parameters of all elements of the path and its entirety are within the limits defined in the settings.
Despite its small size, the multi-touch screen allows you to zoom in on parts of the reflectogram for detailed analysis of events in the optical path. The screen's rotation function allows the reflectogram to be analyzed in both vertical and horizontal positions.
The menu layout and navigation are extremely accessible right from the start of working with the device. The way to edit parameters and activate and deactivate selected functions is instantaneous. In addition, navigation via the touchscreen and gestures known from smartphones greatly enhances the user experience.
Parameters such as wavelength, averaging time, pulse width, and measurement range are set using sliders. Access to basic and advanced options is obtained with one touch on the screen. The sheer number of options that can be set is not overwhelming, which makes this device extremely simple and understandable to use.

To download the measurement files to the computer, simply connect the device to the computer using a USB type C cable (included) and activate the communication function with the computer. The OTDR is then recognized as a removable memory device.
The device has a built-in memory of 30 MB. This allows up to 1,000 measurement files to be stored, depending on whether the files are OTDR or iOLA module files, or both, and whether files are generated for one or both wavelengths. In addition, the u-Disc function allows you to connect an external memory device (such as a small flash drive) to the USB-C port and write files directly to it. With a capacity of 16 GB, the number of possible results to be saved will exceed one hundred thousand.
The OTDR Assistant for PC application allows you to read *.sor (Telcordia SR-4731 standard) measurement files generated by the OTDR for accurate analysis. It is possible to freely navigate through the reflectogram, zoom in on parts of it, or determine the attenuation of a given section or event using markers (2-point method, 4-point method, LSA method). The application also has an iOLA plugin for reading the *tor files generated when the results of the iOLA module are saved.
The saved files and the above-mentioned software allow the generation of measurement reports in *.pdf or *.xls format. The Measurement Report Wizard gives you a choice as to the format and content of the report. You can choose between a one-page document containing basic information, or advanced reports including such data as a reflectogram, event tables, or graphical representation of the measured link.
The device is equipped with a 2000 mAh LiPo battery charged via a USB-C port (a typical 5V/1A charger is sufficient for this). Typical operating time on a single charge is 4h. It is, of course, possible to connect an external power source such as a power bank to the USB port, which will easily extend the uninterrupted working time to a full working day.
ULTIMODE OR-20-S3S5-iSMV combines the functionality of several devices – in addition to the basic function of the OTDR, the user can benefit from an optical power meter (OPM), light source (OLS), visual fault locator (VFL) and flashlight (LED). As a result, the device can be used for both quick connection diagnostics and more advanced measurements.
Note: the warranty period for the battery is 12 months.
