Overview
IEC 61753-087-2:2010 is an international standard published by the International Electrotechnical Commission (IEC) focusing on fibre optic interconnecting devices and passive components. Specifically, it sets the minimum performance, testing, and measurement requirements for non-connectorized single-mode bidirectional wide wavelength division multiplexing (WWDM) devices operating at 1310 nm upstream and 1490 nm downstream wavelengths. The scope of this standard targets devices designed for Category C environments-controlled environments as defined in IEC 61753-1:2007.
This standard defines the criteria WWDM passive optical network (PON) devices must meet to ensure reliable operation in controlled, less harsh environments typically found in indoor or central office installations. It addresses devices used in bidirectional communications where upstream and downstream signals share a single optical fibre but operate at separate wavelengths.
Key Topics
-
Performance Requirements: Establishes key parameters such as insertion loss maximums, wavelength isolation, and dimensional tolerances that WWDM devices must meet. For example, maximum insertion loss is limited to 0.8 dB with measurement uncertainty of ±0.1 dB.
-
Test Methods: References IEC 61300 series for standardized test procedures including vibration, shock, temperature cycling, and optical power handling. These tests validate the physical and optical reliability of pigtailed WWDM components.
-
Sample Size and Test Reporting: Specifies how many samples must undergo testing to ensure statistical validity and mandates comprehensive documentation and test reports for traceability and compliance verification.
-
Device Scope: Applies to non-connectorized single-mode fibre WWDM devices designed for upstream transmission near 1310 nm and downstream near 1490 nm wavelengths, consistent with ITU-T G.983.3 and G.984.2 recommendations.
-
Environmental Category: Devices compliant with this standard fall under Category C, meaning they are intended for controlled environments with stable temperature and humidity conditions.
Applications
-
Passive Optical Networks (PON): IEC 61753-087-2:2010 directly supports the deployment of WWDM components in PON architectures widely used by telecommunications providers for fiber-to-the-home (FTTH) and fiber-to-the-premises (FTTP) services.
-
Central Office Equipment: Devices certified under this standard are suitable for installation in central offices and controlled indoor environments requiring reliable bidirectional fibre optic communication over wavelength multiplexed channels.
-
Network Equipment Manufacturing: Manufacturers producing fibre optic pigtailed WWDM devices leverage this standard to ensure product interoperability and compliance with international performance expectations.
-
Telecom Infrastructure Planning: Network planners and engineers utilize the performance criteria established to specify components that meet the required optical performance and durability within controlled settings.
