TIA TIA-455-44-B

W/D S/S BY TIA-455-176-A

Intent

This is a method for measuring the refractive index profile, includingcore, cladding, and barrier layers of single-mode and class Ia multimodefibers.It is destructive in the sense that a freshly cleaved end isrequired.Scans are generally taken along a diameter of the fiber end,and data are displayed as relative index of refraction as a function ofradius.It is possible to obtain normalized core-cladding indexdifferences with an accuracy of +/-0.001; absolute values of index areless precise.A spatial resolution of less that 1 µm is obtainable; 0.2micro;m has been reported.Core or cladding diameter may be measured to anaccuracy of 1 µm.FOTP-44 may be used in conjunction with FOTP-58 orFOTP-177 to determine the core diameter and numerical aperture of
