| Subject of the standard: | IEC 61280-4-3: 2022 describes the measurement of attenuation, optical return loss and optical power in installed passive optical networks (PONs) using single-mode fibre. This document specifies two methods for measuring the attenuation before activation of the PON: method A: one-cord method using a light source and a power meter (LSPM); method B: optical time-domain reflectometer (OTDR) method in upstream direction only, with reduction of uncertainties due to the variation of backscatter coefficient.activation of the PON by using a U band filtered optical time-domain reflectometer (FOTDR) in an upstream direction. |
