IEC 61202-1: 2016(E) 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 fibre optic connector;

- they are passive devices containing no opto-electronic or other transducing elements;

- they have two optical ports for directionally transmitting optical power. This fourth edition cancels and replaces the third edition published in 2009. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

- the terms and definitions were reconsidered;

- quality assessment level was deleted from classification;

- the clause numbers of Annexes A and B have been rearranged.
