Overview
IEC 61753-086-6:2010 is an international performance standard established by the International Electrotechnical Commission (IEC). This standard specifies the minimum initial performance, test, and measurement requirements for non-connectorized, single-mode, bidirectional wide wavelength division multiplexing (WWDM) devices used in passive optical networks (PONs). Designed for category O environments-uncontrolled and potentially harsh conditions-this document ensures reliable operation of fibre optic pigtailed devices operating at:
- Downstream wavelengths: 1 490 nm and 1 550 nm
- Upstream wavelength: 1 310 nm
The standard defines necessary performance metrics to qualify devices used in WWDM PONs, critical for robust fiber optic communication systems in uncontrolled environments.
Key Topics
-
Scope and Application: IEC 61753-086-6 targets fibre optic WWDM devices without connectors, focusing on single-mode fiber technology for bidirectional communication in passive optical networks.
-
Performance Criteria: The standard outlines essential performance requirements including optical characteristics, physical dimensions, and environmental durability needed to comply with category O standards for uncontrolled environments.
-
Test Methods: Tests are based on the IEC 61300 series, including vibration, shock, temperature-humidity cycling, torsion, fibre retention, and optical power handling. Measurements are conducted at key wavelength ranges consistent with ITU-T and IEEE standards, ensuring devices meet stringent operational conditions.
-
Sample Handling: Detailed guidelines on sample size, sequencing, and grouping of tests are included to guarantee statistically relevant and reproducible results for device qualification.
-
Documentation and Reporting: Comprehensive test reports must document all testing procedures and evidence of compliance to provide traceability and support quality assurance.
Applications
This standard is essential for manufacturers, developers, and quality assurance professionals in the fibre optics sector who design or validate WWDM PON passive components. Typical applications include:
-
Passive Optical Network (PON) Infrastructure: Ensures WWDM devices achieve reliable bidirectional signal transmission for telecom operators deploying 1 490/1 550 nm downstream and 1 310 nm upstream links.
-
Telecommunications Networks: Provides assurance that fibre optic interconnecting devices survive uncontrolled environmental conditions such as outdoor or indoor non-climate-controlled environments.
-
Network Equipment Manufacturing: Assists manufacturers in adhering to internationally recognized performance benchmarks, facilitating global market acceptance.
-
Quality Control and Certification: Supports conformity assessments for fibre optic passive components used in next-generation broadband access systems.
