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.
