Excerpt from Technical Digest, Symposium on Optical Fiber Measurements, 1980
Because of chromatic aberrations of the microscope objective lenses, the launch optics has to be readjusted for na-dependent loss measurements in the 1.3um wavelength region. The loss-versus-na de pendencies of several sub - 1 db/km ge-p - doped fibers measured at pm are similar to those observed at 0.82um some with a steadily increasing, and some with a parabolic dependence) (fig. MW data were typically within to 0.2db/km (max. Difference) of the steady - state losses determined with matched-beam launch optics.
