The following items are set and displayed when installing the O/E
converter.
Table 8.3.1-1 O/E Converter Setting Items
Item Description
Filter On/Off When installing the Option 086, the internal low pass
filter is set to On/Off.
Filter Selection Sets the internal low pass filter when one of the Options
063, 065, 069, and 087 to 089 is installed.
Wavelength Select the wavelength of input light from the following:
850 nm, 1310 nm, 1550 nm, User
The Responsivity, Conversion Gain, or System
Conversion Gain varies depending on the wavelength.
Conversion Gain* Indicates the conversion ratio of the O/E.
The setting range is from 1 to 9999 (V/W).
System Conversion
Gain*
Indicates the conversion ratio between the power input to
the O/E Data In and the voltage displayed on the Result
window. This is automatically set by Conversion Gain,
internal loss of the BERTWave, and filter loss:

Used for calculating filter loss when one of the Options
070 to 073, 075, 076, 078 to 082, and 086 is added. The
loss varies with the filter types.
Responsivity* Rate at which photodiode converts optical power to
current
The setting range is from 0.001 to 999.999.
Calibration Automatically adjusts the Conversion Gain/ Responsivity
/System Conversion Gain values. For adjustment, refer to
8.3.3 “Adjusting values for changing the wavelength
bands”.
Input Power Setting used when adjusting Conversion Gain/
Responsivity /System Conversion Gain.
For adjustment, refer to 8.3.3 “Adjusting values for
changing the wavelength bands”.
Extinction Ratio
Correction
Sets whether to correct the Extinction Ratio
measurement.
Extinction Ratio
Correction Factor
Indicates the correction factor of Extinction Ratio The
setting range is from –9.99 to 9.99%.
O/E Calibration Starts module calibration.
*: Changes in the setting values of Conversion Gain, Responsivity and
System Conversion Gain are not required when measuring an optical
signal at a wavelength of 850 nm, 1310 nm or 1550 nm.
