scope:

Applies to isolators used in the field of fibre optics, all exhibiting the following features: - they are non-reciprocal optical devices, in which each port is either an optical fibre or optical fibre connector; - they are passive components containing no opto-electronic or other transducing elements; - they have two optical ports for directionally transmitting optical power. This standard establishes uniform requirements for the following points: - fibre optic isolator requirements; - quality assessment procedures.
