850 nm Calibration Adjustment
1. Set the switch on the FOM to the 850 nm
2. Connect the light source to the reference power
3. Connect the 850 nm light source to the FOM.
4. Adjust R1 for an output on the DMM of P o
5. Apply insulating varnish, such as red GLPT, to
1550 nm Calibration Adjustment
1. Set the switch on the FOM to the 1550 nm
2. Connect the light source to the reference power
3. Connect the 1550 nm light source to the FOM.
4. Adjust R3 for an output on the DMM of P o
