BS EN IEC 61753-086-02:2025

Fibre optic interconnecting devices and passive components. Performance standard. Non-connectorized single-mode bidirectional 1490 / 1550 nm downstream and 1 310 nm upstream WWDM devices for category C. Indoor controlled environment | Status: Current

1 Scope This part of IEC 61753 contains the minimum initial performance, test and measurement requirements and severities which a fibre optic pigtailed 1 490/1 550 nm downstream and 1 310 nm upstream wide wavelength division multiplexing (WWDM) passive optical network (PON) device will satisfy in order to be categorized as meeting the requirements of category C (indoor controlled environment), as defined in IEC 61753‑1:2018, Annex A. WWDM is defined in IEC 62074‑1. Annex B gives general information for these PON WWDM devices.
