Fibre optic interconnecting devices and passive components performance standard - Non-connectorised single-mode bidirectional 1490 / 1550 nm downstream 1310 nm upstream WWDM devices for category C. Controlled environment Ingestion-build-54371 In the interest of implementing1 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 must satisfy in order to be categorized as meeting the requirements of category C (controlled environments), as defined in Annex A of IEC 617531. Annex B of this standard
