Figure B–2. This responsivity curve is applicable to both the displayed wave-
form and the mean power monitor output.
The SD-46 Optical-to-Electrical Converter Head is calibrated for response to
optical signals with wavelength of 1300 nm
±
20 nm. Optical signals with
wavelengths in the range of 1200 nm to 1650 nm can be analyzed using the
SD-46 with the responsivity as a function of wavelength being given in
Figure B–4. This responsivity curve is applicable to both the displayed wave-
form and the mean power monitor output.
