Fiber Optics Cable Field Calibration and Testing
Calculated Loss Budget lets FIBERTEK calculate the limits for each wavelength
based on parameters you specify. Fiber length, number of connectors and splices, and
maximum attenuation for each of these are entered into the calculator to determine
the proper loss budget.
Setting the Loss Budget
1.
Select a wavelength by pressing the F1–F4 keys.
2.
Use the ARROW keys and NUMERIC keypad to enter a value into the Loss Budget
field.
3.
Select another wavelength with the F1-F4 keys and enter the loss budget.
4.
Press ENTER to complete the process.

Press the SHIFT key and then select
to enter the Budget Loss Calculator.
3.
Using the UP/DOWN ARROW keys to move between fields, and the
LEFT/RIGHT ARROW keys to scroll through a field, enter values with the
NUMERIC keypad for cable length, loss/km, splices, connectors, and repair
margin.
4.
Press
to update the budget then press ENTER to save. Repeat for each
wavelength. Press
again to store values and return to the READY screen.
