scope:

This part of IEC 61300 describes methods for quantitatively assessing the endface quality of a polished fibre optic connector and of a fibre optic transceiver using a fibre-stub type interface. The information is intended for use with other standards which set requirements for allowable surface anomalies such as scratches and defects which may affect optical performance. Sub surface cracks and fractures are not considered in this standard. In general, the methods described in this standard apply to 125 µm cladding fibres contained within a ferrule and intended for use with sources of = 2 W of input power. However, portions are applicable to non-ferruled connectors and other fibre types. Those portions are identified where appropriate.
