Calibration Overview

User Calibrations—Optical and Electrical

O/E User-Wavelength Calibration

This optional optical/electrical (O/E) calibration is for optical measurements
only. It compensates for the photodetector’s responsivity. The vertical accu-
racy of all optical channel user wavelength measurements is dependent on
proper O/E user wavelength calibration. O/E user-wavelength calibrations
should be performed annually or whenever a new wavelength is being mea-
sured. To perform a O/E user-wavelength calibration, a CW optical source with
a known optical output power level is required. Refer to the specifications for
the plug-in module for the acceptable power level ranges.
