Performance Tests

Performance Test

1. Set the attenuator as follows:

λ

as required

CAL

to 0.00 dB

ATT

to 0.00 dB

2.Connect the equipment as shown in the appropriate Total Insertion Loss Test Setup 2.

NO T E

Use a tape to fix the fibers on the table. Don’t touch the fibers during

 

the measurement to prevent changes of state of polarization.

 

 

3.Zero the power meter channel and make sure that the parameters are set as follows:

λ

as required

CAL

to 0.000 dB

T

to 500ms

4.Set the power meter to AUTOrange, then enable the laser source and the attenuator output.

5.On the power meter select display in dB (dB key)

6.Press DISP→ REF for the power meter.

7.Set the DUT attenuation to 60dB

8.If the powermeter does not show 60.00dB, set [lambda] on the DUT so that the power meter shows 60.00dB. Tuning the DUT in 0.1nm steps is sufficient to accomplish this. This is necessary to eliminate the wavelength dependence of the DUT.

9.Press and hold ATT until the attenuation resets to 0.000dB.

10.Press DISP→ REF for the power meter.

11.Increase the DUT attenuation in steps as shown below and note the power meter reading in the Test Record.
