Summary:
|
Recommendation ITU-T G.650.1 contains definitions of the linear, deterministic parameters of single-mode optical fibres and cables. It also contains both reference test methods and alternative test methods for characterizing these parameters.
These test methods are suitable mainly for factory measurements of the linear, deterministic attributes of single-mode fibres and cables. Some of the test methods may also be used to characterize discrete optical components.
This revision is to add clause “3.4 Coating geometry characteristics” and “6.3 Test methods for the primary coating diameter and primary coating-cladding concentricity error” to define definitions and measurement methods.
