Setting Macrobend Parameters
Setting Macrobend Parameters
Note: This function is available only with the optional FTTx software package.
Your unit can locate macrobends by comparing the loss values measured 
at a certain location, for a certain wavelength (for example, 1310 nm) with 
the loss values measured at the corresponding location, but for a greater 
wavelength (for example, 1550 nm).
The unit will identify a macrobend when comparing two loss values if:
³
Of the two loss values, the greater loss occurred at the greater 
wavelength.
AND
³
The difference between the two loss values exceeds 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.
You can also disable macrobend detection.
Note: Macrobend detection is only possible with singlemode wavelengths.
