IEC 61753-089-2 Ed. 1.0 en:2013

IEC 61753-089-2:2013(E) 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. Keywords: wide wavelength division multiplexing (WWDM), passive optical networks (PON), optical time-domain reflectometer (OTDR)
