Performance Tests
Performance Test
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.
NOTE 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.
NOTE 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.
