Fibre optic interconnecting devices and passive components. Performance standard - Single-mode fibre non-connectorized fixed attenuator. Category O in outside plant environment Ingestion-build-100580 Acceptance criteria are not defined1 Scope This part of IEC 61753 contains the minimum initial test and measurement requirements and severities which a fibre optic attenuator satisfies in order to be categorised as meeting the requirements of single mode fibre non connectorized fixed attenuator devices used in outside plant environments. IEC 608691 contains the generic specification of the optical attenuator. Optical performances specified in this document relate only to non
