About This Item
IEC 61280-4-5:2020/COR1:2022 provides a corrigendum to the fibre-optic communication subsystem test procedures for installed cabling plant, specifically the attenuation measurement of MPO-terminated fibre optic cabling plant using test equipment with MPO interfaces. It is relevant where engineering teams, laboratories, and procurement groups need to align documentation and test practice with the corrected reference. As a supporting document to IEC 61280-4-5:2020, it helps maintain technical accuracy in verification activities, documented evaluation, and conformity assessment workflows.
What is IEC 61280-4-5:2020/COR1:2022?
This document is a corrigendum linked to IEC 61280-4-5:2020, so it should be used as a modifying reference rather than treated as a standalone testing standard. Its role is to correct or clarify the published guidance for attenuation measurement of MPO-terminated fibre optic cabling plant using test equipment with MPO interfaces. For organizations carrying out technical review, laboratory evaluation, or compliance preparation, the corrigendum helps ensure the parent document is applied as intended in engineering documentation and testing workflows.
Applications of IEC 61280-4-5:2020/COR1:2022
IEC 61280-4-5:2020/COR1:2022 is typically used in fibre-optic installation, inspection, and acceptance testing activities where MPO-terminated cabling must be measured in a controlled and repeatable way. It is relevant to test labs, network deployment teams, and quality assurance functions that manage installed cabling plant performance checks. The corrigendum may also support procurement review and regulatory preparation when the corrected technical reference is needed for specification control, supplier documentation, or project-level compliance workflows.
Why is IEC 61280-4-5:2020/COR1:2022 important?
Corrective documents like IEC 61280-4-5:2020/COR1:2022 matter because small wording or technical corrections can affect how test results are interpreted and recorded. In fibre-optic cabling projects, consistent attenuation measurement practices support interoperability, quality assurance, and reduced risk during acceptance and maintenance. Using the corrigendum alongside the parent reference can improve technical validation, strengthen conformity assessment preparation, and help organizations keep engineering specifications aligned with the intended test procedure.
