Set up equipment 11 Set the DUT to 1310.00 nm.

12 Enable the laser source and the Agilent 8156A output,

and wait 3 minutes until the laser has settled.

13 Set the DUT to display power levels in W.

Note result in test record 14 Note the displayed measured value on the DUT in the

test record.

Test of the other wavelength

Repeat for other wavelength 15 Set the laser source to 1550 nm (nominal), and set the

attenuator and the DUT to 1550.00 nm.

16 Repeat steps 1 to 14 for this wavelength, replacing all

settings of 1310 nm/1310.00 nm by 1550 nm/

1550.00 nm.

NOTE The Reference Power Meter 81524A and the DUT are both

of the same type InGaAs. This means that the wavelength

dependencies are equal.

As long as both the Reference Power Meter and the DUT

are set to the same wavelength, the actual wavelength of

the source does not noticeably add to measurement

uncertainties, if the source is within a

±20 nm limit of the

measuring wavelength.

Total Uncertainty/Accuracy Test

NOTE Make sure that all equipment has warmed up, and all

connectors are clean.

Make sure that all patchcords are fixed to the table and

will not move during measurements.

Repeat each of the following steps for each of the

specified wavelengths.
