Fibre optic interconnecting devices and passive components. Performance standard -- Non-connectorized single-mode bidirectional OTDR monitoring WWDM devices for category C. Controlled environment
This part of IEC 61753 contains the *minimum initial performance, test and measurement requirements and severities* which a fibre optic pigtailed wide wavelength division multiplexing (WWDM) device for monitoring passive optical networks (PON) using an optical time-domain reflectometer (OTDR) satisfies in order to be categorized as meeting the requirements of **category C (controlled environments)**, as defined in Annex A of IEC 61753-1:2007.
Annex B of this standard provides information concerning the *principle and function* of the OTDR monitoring WWDM.
