Description / Abstract:
Introduction
Intent
This test method describes a procedure for measuring the
polarization-mode dispersion (PMD) of single-mode optical fibers.
It produces a single measurement value that represents the PMD over
the measurement wavelength range of typically a few hundred
nanometers. The method can be applied to both short and long fibers
in the limits of both zero and strong polarization mode coupling.
Under some circumstances, repeated measurements are necessary to
achieve satisfactory precision using this FOTP - see Annex A.
The procedure is restricted to wavelengths greater than or equal
to that at which the fiber is effectively single-mode.
