Performing an OTDR test involves careful setup and analysis. Set Parameters: Choose wavelength (e. Acquire Trace: Run the test and capture the. Download free OTDR Trainer Software for PCs After you study this page, you can download a free OTDR Trainer to run on your PC. It can verify splice loss, measure length and find faults. The OTDR. · Automatic / manual OTDR mode: multi pulse width test + automatic analysis · High speed test, accurate results and high repeatability · Simple operation, no training, easy to start · Long battery life, unique replaceable smart battery · Adapt to a variety of environments Product Description The. There are a number of test tools available that address the different testing needs at various stages of the network, such as fiber commissioning. Used to reveal the total loss, optical return loss (ORL) and the fiber length, such tests can be performed either on a single fiber or on a complete. Ensure the integrity of your fiber optic network with an Optical Time Domain Reflectometer (OTDR). OTDR testing analyzes fiber optic cable performance from end to end by testing components along the cable, including connection points, bends, and splices. Measure at 850nm (for short-range) and 1310nm or 1550nm (for longer distances). A shorter pulse, like 5 nanoseconds (ns), gives you fantastic resolution and smaller dead zones, allowing you to distinguish events that are very close together.
