Fibre optic interconnecting devices and passive components. Basic test and measurement procedures - Examinations and measurements. Error and repeatability of the attenuation settings of a variable optical attenuator Ingestion-build-224916 Integrating or converting terminological data1 Scope This part of IEC 61300 provides a method to measure the error and repeatability of the attenuation value settings of a variable optical attenuator (VOA). There are two control technologies for VOAs, manually controlled and electrically controlled. This standard covers both control technologies of VOAs and also covers both single mode and multimode fibre VOAs.
