IEC 61300-3-42:2007

IEC 61300-3-42:2007 defines a test and measurement procedure for examining attenuation in single mode alignment sleeves and adaptors with resilient alignment sleeves, within the fibre optic interconnecting devices and passive components series. It is relevant to engineers and laboratories that need a clear technical reference for evaluating optical interface performance, supporting documented evaluation, quality workflows, and conformity assessment. As a primary technical reference, IEC 61300-3-42:2007 helps organizations align verification activities with a recognized method when reviewing component behavior in fibre optic systems.

Purpose of IEC 61300-3-42:2007

The purpose of this document is to provide a controlled procedure for examining and measuring attenuation in specific fibre optic alignment components. By focusing on single mode alignment sleeves and adaptors with resilient alignment sleeves, it supports technical review of interfaces that can affect transmission performance and operational consistency. Organizations may use it to structure laboratory evaluation, compare results across testing workflows, and support technical compliance decisions during product development, qualification, or procurement review.

Compliance applications of IEC 61300-3-42:2007

IEC 61300-3-42:2007 is commonly used where fibre optic passive components must be checked against defined measurement expectations during engineering documentation and regulatory preparation. It can support product evaluation for interconnecting devices, connector adaptors, and related optical assemblies where attenuation behavior matters to system performance. Test laboratories, manufacturers, and conformity assessment teams may use the reference to guide consistent measurements, improve repeatability, and document results for acceptance decisions, supplier qualification, or internal technical validation.

Benefits of IEC 61300-3-42:2007

Using IEC 61300-3-42:2007 can improve testing consistency and reduce uncertainty when assessing attenuation in fibre optic alignment components. It provides a structured basis for comparison, which is valuable for quality assurance, procurement checks, and risk management in product release processes. The document also supports interoperability-focused engineering reviews by helping teams evaluate whether components meet expected optical behavior under controlled conditions. For organizations preparing conformity assessment records, it offers a practical compliance reference for repeatable laboratory evaluation.
