5.4 Fiber Optic Measurements with OMNIFiber
5.4.1LENGTH/DELAY
The Length/Delay function measures a fiber’s length and propagation delay. Length measurements are derived from the propagation delay results using the GRI (Graded Refractive Index) at the appropriate wavelength.
Propagation Delay is the measure of the time required for a signal to advance from one end of the link to the other. When measuring propagation delay, OMNIScanner measures the round trip delay through both fibers, and then divides the result by two, assuming that the cables are equal in length.
Propagation Delay cannot be measured on a
OMNIScanner measures the full length of the fibers under test.
