Changing OTDR Settings

Setting Macrobend Tolerances

FastReporter can locate macrobends by comparing the loss of events

occurring at a certain wavelength (for example, 1310 nm) with the loss of

the corresponding events at a greater wavelength (for example, 1550 nm).

FastReporter will identify a macrobend when comparing two events if:

³ Of the two events, the greater loss occurred at the greater wavelength.

AND

³ The difference between the loss of two events exceed the defined

delta loss value. The default delta loss value is 0.5 dB (which is suitable

for most fibers), but you can modify it.

Changes made to event matching tolerances will affect macrobends.
