WebConfiguration settings include index of refraction (IOR), pulse width, range, wavelength, dead zone, event dead zone, masking, noise floor, and loss variables. Acceptance testing consists of checking two-point attenuation, the index of refraction vs. the actual cable length, and zooming in to correctly place markers. WebEvent dead zone: the minimum distance after a Fresnel reflection where an OTDR can detect another event. In other words, it is the minimum length of fiber needed between two reflective events. Pulse width: the time during which the laser is on. Since time is converted into distance, pulse width has a length. selling to grainger supplies https://boldnraw.com

WebIt was reflected back toward the OTDR and then reflected back to the far end and then reflected back again to the OTDR where it showed up on the trace as a peak, bouncing back and forth in the fiber. The trace did indeed look like there was a break in the cable, but the location of the first peak was a dead giveaway—it was at the actual length of the cable. WebDec 1, 1999 · Dynamic Range Still Key Spec. Dynamic range remains one of the most important characteristics of an OTDR because that spec determines the maximum observable length of a fibre. The higher the dynamic range, the higher the signal-to-noise ratio and the clearer the display will be, and the better the event detection. http://documents.exfo.com/Products/UserGuides/User_Guide_OTDR_English_(1068770).pdf selling to homeowner associations
