OTDR optical cable test pulse width
OTDR test pulse width: then set the OTDR test pulse width to the shortest pulse width available, which will provide the highest resolution, giving the best "picture" of the fiber being tested. This is usually listed in nanoseconds (ns), with typical choices of 10 to 30 ns. OTDR settings are a balance between dynamic range, acquisition time, spatial resolution and accuracy. OTDR (Optical Time-Domain Reflectometer) is such a powerful test instruments for fiber optic cable testing: when used properly, it not only simplifies testing requirements, but also help to increase the reliability and value of the network. also depends on the type of network to be characterised (overall length, density of optical devices).
