What is BS EN 60793-1-44 - Optical fibres about?
BS EN 60793 is a series on optical fibres. Optical fibres are cylindrical dielectric waveguide (nonconducting waveguide) that transmits light along their axis through the process of total internal reflection. BS EN 60793-1-44 establishes uniform requirements for measuring the cut-off wavelength of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. BS EN 60793-1-44 gives the methods for measuring the cut-off wavelength of fibre and cable.
The test method in BS EN 60793-1-44 describes procedures for determining the cut-off wavelength of a sample fibre in either an uncabled condition
