This part of IEC 61202 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.
