WebMay 24, 2013 · OTDR working principle and OTDR characteristics are extensively introduced in this article. An OTDR tester is essentially an optical radar. It sends out a flash of bright light and measures the intensity of echo or reflections. So this weak signal is averaged to reduce detection noise. Besides computation is used to display a trace and make a ... WebOTDR II Tester. R230000. Tablet-inspired design. 7-inch, outdoor-enhanced touchscreen.

WebThe OTDR II is the first tablet inspired OTDR that is handy, lightweight and rugged enough for any environment. With a 7-inch outdoor enhanced touchscreen, the most efficient hand held display in the industry, it delivers an unprecedented user experience. Its intuitive user interface including onboard manual ensures a fast learning curve. WebAn OTDR’s performance can be accurately evaluated by briefly examining the following key specifications: Dynamic range describes the loss and distance measurement capability. Measured in decibels, it is the difference between the backscatter level at the front end of the fiber and the noise floor at the end of the fiber. WebOTDR gain (Raman gain) as a function of WDM power for a 25 km SMF fiber, experimental data (dot) and theoretical data (solid line) for a 10 mW OTDR pulse power. OTDR Penalty Due to Spontaneous Raman Scattering The most troublesome impact that can be seen in Figure 4 is the rise in noise floor on the OTDR trace. location of protons electrons neutrons
