Performance Tests

Technology (NIST), will be covered in a manual change supplement, or revised manual. Such specifications supersede any that were previously published.

D.5 Performance Test

The performance test given in this section includes the Total Insertion Loss Test, the Attenuation Accuracy Test, the Attenuation Repeatability Test, and the Return Loss Test. Perform each step in the order given, using the corresponding test equipment.

The performance test should be performed once at 1310nm, and then repeated at 1550nm.

If you are testing options 100, 101 or 121, you will need to change the isolator when changing wavelength.

If you are using two separate sources, you will need to change them when changing wavelength.

Make sure that all optical connections of the test setups given in the procedure are dry and clean. DO NOT USE INDEX MATCHING OIL. Make sure that all optical connectors are undamaged. The value for insertion loss depends on the quality of the connectors.

The optical cables from the laser source to and from the Agilent 8156A Attenuator to the power meter must be fixed on the table to ensure minimum cable movement during the tests.

The environmental conditions (temperature and relative humidity) must remain constant during the tests.
