IEC 61753-041-2:2014 contains the minimum initial performance, test and measurement requirements and severities which a fibre optic non-connectorized OTDR reflecting device for monitoring point to point (PTP) or point to multipoint (PTMP) passive optical networks (PON) using an optical time-domain reflectometer (OTDR) should satisfy in order to be categorized as meeting the requirements of category C (controlled environments), as defined in Annex A of IEC 61753-1:2007. Keywords: fibre optic non-connectorized OTDR reflecting device, point to point (PTP), point to multipoint (PTMP), passive optical networks (PON), category C (controlled environments), optical time-domain reflectometer
