Importance of OTDR – blind areaadmin
Short attenuation blind area makes OTDR not only can detect continuous events, but also can return a very close event loss. For example, you can learn the loss of short fiber optic fiber network, which can help technicians understand the situation within the link.
Blind area is also affected by other factors: pulse width. The shortest pulse width is used to provide the shortest blind area. However, the blind area is not always the same length, with the pulse width, blind will stretch. The use of the longest possible pulse broadband will result in a particularly long blind spot, but this has different uses.
