OTDR/tester ULTIMODE OR-30-S3S5S62B-iSMV pentru rețele de fibră optică și cupru

OTDR ULTIMODE OR-30-S3S5S62B-iSMV is a device designed for measuring and diagnosing optical fibre connections. It combines the functions of: an OTDR, optical power meter, light source and visual fault locator. In addition, it has the function of copper cable locator (operating in analog or digital mode), and the function of connection map for twisted-pair cables. Thus, it provides a universal installation diagnostic tool for telecom network contractors and others. The device generates pulses at three wavelengths: 1310 nm, 1550 nm and 1625 nm. This enables full diagnostics of the optical path in terms of fiber attenuation, splices, connectors, as well as events such as fiber bending and cable bending or breakage. A 1625 nm wavelength is available on a second OTDR connector equipped with filters for lower wavelengths, making it possible to perform measurements on active line in GPON networks and beyond. The dynamic range of 32/30 dB makes it possible to check connections on cables as long as tens of kilometers, including splitters. Why a 3-wave OTDR? Having an OTDR device with the ability to make measurements at 3 wavelengths comes with a number of benefits. The first is the ability to provide service to a variety of customers, regardless of their requirements. Among the requirements for performing reflectometry measurements, one can find both, those in which the customer expects measurements for 1310 nm and 1550 nm and those in which only measurements at 1625 nm are expected (mainly measurements in the networks of larger operators). The OR-30 L5835 allows for each of these types of assignments. Another benefit is the possibility of full diagnostics of the system being made. The additional 1625 nm laser makes it possible to detect any macro-bends in the system that would not necessarily manifest themselves with 1310/1550 nm measurements. The higher wavelength, due to occupying a larger area of the MFD in the fiber, is more sensitive to leakage at bends, resulting in increased attenuation. However, it is also worth taking measurements at lower wavelengths, because it is at these wavelengths that transmission is usually realized, and the 1310 nm wavelength sometimes allows to highlight problems with fiber positioning (poor connectors, splices). To summarize, 3-wave measurement is a complete measurement and provides full information about the network. Example of a 3-wavelength measurement where the measurement at higher wavelengths highlighted a problem at a splice location. The problem, however, is not the splice itself, but the bend in the fiber that occurs right behind it. Event number 2 is a combination (splice) of fibers in G.652.D and G.657.B3. When measured at a wavelength of 1310 nm, an apparent signal amplification (gain) of 0.104 dB was recorded at this location, as expected (screenshot on the left) – you can read more about "gainers" here. This is the correct combination. The measurement at 1550 nm gives a worse result – an attenuation of 0.233 dB appears at the apparent gain spot (middle screenshot), which is a poor result for a splice and suggests that there may be a kink there. This is finally confirmed by a measurement at 1625 nm, which gives a result of 0.717 dB at this location (screenshot on the right). After eliminating the kink on the fiber, the measurement at 1310 nm did not change, while for higher wavelengths this connection became invisible in the measurement. Special features of ULTIMODE OR-30-S3S5S62B-iSMV include compact size and convenience of use. The device features a 5-inch LCD touchscreen with 800x400 p resolution and rubber function keys, making operation of the OTDR and use of basic functions quick and intuitive. Simple and intuitive interface allows for easy navigation and quick measurements. For this reason, the device is well suited for installers who have no experience with this type of equipment. The results of measurements taken 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 microSD card (not included). 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. After the measurement in OTDR mode, the user has a choice of 4 tabs in which to analyze the results. The “Test Curve” tab allows the user to view the reflectogram and the event table. “Event list” contains only the event table. The "Event map" tab contains a graphical representation of the measured line – the OTDR analyzes the parameters of the events and assigns them an appropriate icon (splice, joint, macro bend, etc.). After pointing to the selected element, the user gets access to information on its parameters. The “Analysis” tab can be used for detailed analysis of selected events or fragments of a connection.
