Bibliography
Determines uniform requirements for measuring the coating geometry of optical fibre. Coating geometry measurements are fundamental values that need to be known for subsequent procedures such as cabling, connectorization, splicing, handling and for making other measurements.

Gives four methods for measuring the coating geometry of optical fibres. The following parameters are measured: coating diameter, coating non-circularity, coating-cladding concentricity error. The methods are conducted off-line during inspection. They are not suitable for on-line, in-process measurements.
