EN IEC 61753-022-02:2026

IEC 61753-022-02: 2026 defines the minimum initial test and measurement requirements and severities which multimode fibre optic connectors terminated as a pigtail or patchcord satisfy in order to be categorized as meeting the IEC standard category C (controlled environment), as defined in IEC 61753‑1. This first edition cancels and replaces the second edition of IEC 61753-022-2 published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:a) addition of provisions for rectangular ferrule connectors;b) additions of terms and definitions;c) update of the fibre naming conventions in accordance with IEC 60793-2-10;d) update of test severities in accordance with IEC 61753‑1;e) addition of the torsion test;f) reduction of the duration of the fibre/cable retention test on reinforced cables from 120 s to 60 s minimum;g) deletion of the static side load test;h) update of the flexing of the strain relief test to use the change in attenuation instead of the transient loss;i) reduction of the number of mating durability cycles for cylindrical ferrule connectors from 500 cycles to 200 cycles;j) addition of the mating durability for rectangular ferrule connectors with 50 cycles;k) addition of Annex B for visual examination of the outer cable sheath movement of reinforced cables as an additional requirement for change of temperature, cable retention and flexing of the strain relief tests.
