BS EN IEC 61753-084-02:2025

Fibre optic interconnecting devices and passive components. Performance standard. Non connectorised single-mode 980/1550 nm 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 980/1 550 nm wide wavelength division multiplexing (WWDM) 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. The requirements cover devices with single-mode non-connectorised pigtails. This device has three ports; 980 nm port, 1 550 nm port and common port for output or combining 980 nm and 1 550 nm.
