IEC 61753-042-2:2014

Overview

IEC 61753-042-2:2014 is an international standard published by the International Electrotechnical Commission (IEC) that specifies performance requirements for fibre optic interconnecting devices. Specifically, it addresses plug-pigtail-style and plug-receptacle-style OTDR reflecting devices designed for category C – Controlled environments. These devices are essential components used in out-of-band Optical Time-Domain Reflectometer (OTDR) testing within optical fibre systems. The standard establishes minimum performance thresholds, testing methods, and measurement severities required to classify these components under controlled environmental conditions as defined in IEC 61753-1:2007.

Key Topics

• Scope and Purpose: Defines minimum initial performance and test requirements for OTDR reflecting devices of plug-pigtail and plug-receptacle styles intended for controlled environments.
• Device Types Covered:
  • Plug-pigtail-style OTDR reflecting devices
  • Plug-receptacle-style OTDR reflecting devices
• Testing Standards Reference: Aligns with the IEC 61300 series for test and measurement procedures including vibration, shock, optical power endurance, temperature, and humidity tests.
• Optical Fibre Specifications: Requires use of single-mode fibres complying with IEC 60793-2-50 categories B1.1, B1.3, or B6 for sample terminations.
• Performance Parameters: Includes dimensions, polarization dependent loss (PDL), return loss, optical attenuation, and mechanical stability under various environmental stresses.
• Sample Size and Testing Conditions: Specifies the number of test samples, test severities, and details for sample preparation according to device style.
• Annexes:
  • Annex A: Normative guidance on sample size for testing
  • Annex B: Informative details about OTDR reflecting devices’ construction and application

Applications

IEC 61753-042-2:2014 standard is critical for manufacturers, quality assurance professionals, and testing laboratories involved in the production and validation of fibre optic components. Its practical applications include:
