IEC 61753-084-2:2007

Overview

IEC 61753-084-2:2007 is an international standard published by the International Electrotechnical Commission (IEC) that specifies performance requirements for non-connectorised single-mode fibre optic WWDM (Wavelength and Wavelength Division Multiplexing) devices operating at 980 nm and 1550 nm wavelengths. This standard applies specifically to devices used in category C - controlled environments, ensuring reliable functionality under defined, stable environmental conditions.

The document details the minimum initial test procedures, test measurement requirements, and severity levels that fibre optic pigtailed WWDM devices must meet to comply with category C classification. This includes specifying tests for devices with non-connectorised single-mode fibre pigtails designed for controlled environments such as data centers or telecommunication equipment rooms. The standard incorporates the corrigendum issued in September 2008, ensuring it reflects the most current accepted practices and technical accuracy.

Key Topics

• Scope and Application
  IEC 61753-084-2 sets the baseline performance criteria for 980/1550 nm WWDM fibre optic devices without connectors aimed at controlled indoor environments, ensuring device stability and reliability in sensitive or regulated settings.

• Test Procedures and Measurement Requirements
  The standard prescribes detailed testing protocols, including the number of samples required, grouping of tests, and performance parameters such as insertion loss, return loss, isolation, and environmental durability under controlled conditions.

• Device Categorization – Category C
  Category C devices are defined as suitable for environments where temperature, humidity, and other conditions are maintained within specific ranges - typically controlled indoor installations - differentiating them from devices designed for more variable or harsh environments.

• Normative References and Definitions
  IEC 61753-084-2 references the general IEC 61753 series and related fibre optic standards, clarifying terminology, abbreviations, and definitions to provide a consistent framework for measuring performance and quality.

Applications

• Telecommunication Systems
  The standard guides manufacturers and system integrators in ensuring WWDM devices meet quality criteria for optical networks operating in controlled indoor environments, vital for telecom backbone and access networks.

• Data Centers and Enterprise Networks
  Fibre optic hardware used in data centers can leverage this standard to guarantee consistency and interoperability for WWDM devices that handle multiplexed optical signals at 980/1550 nm wavelengths.

• Passive Optical Components Manufacturing
