The noise level can be estimated based on non-vibration images, which can be used to set the threshold for curvelet coefficients.

WebApr 27, 2012 · As mentioned the main question is whether the optical signal getting to the far side is within the thresholds. Here are some ways to do this; Obtain or borrow a power … WebIn MM fibers, the OTDR will underestimate the loss considerably - as much as 3 dB in a 10 dB link - but the amount is unpredictable. In long distance SM links, the difference may be less, but there are other measurement uncertainties, like connector or splice loss, where the OTDR can show a gain.
WebThe following examples show how different splice-loss threshold levels can affect the number of displayed events, especially small non-reflective events such as those caused …
