This procedure is restricted to wavelengths at which the fiber is effectively single-mode. The cutoff wavelength ?cf of an un-cabled fiber may be determined by FOTP-80, while the cutoff wavelength ?cf of a cabled fiber may be determined by FOTP-170.
This method is intended for installed cabled fibers without amplification, with PMD values in the range 0.1 to 20 ps.
