Fibre optic interconnecting devices and passive components. Performance standard - Non-connectorized single-mode bidirectional OTDR monitoring WWDM devices for category C. Controlled environment Ingestion-build-82061 • Terms and definitions1 Scope This part of IEC 61753 contains the minimum initial performance, test and measurement requirements and severities which a fibre optic pigtailed wide wavelength division multiplexing (WWDM) device for monitoring passive optical networks (PON) using an optical time domain reflectometer (OTDR) satisfies in order to be categorized as meeting the requirements of category C (controlled environments), as defined in Annex A of IEC 617531: 2007.
