EVS-EN 61300-3-35:2015

IEC 61300-3-35:2015 describes methods for  quantitatively assessing the end face quality     of a polished fibre optic connector   or of a fibre  optic transceiver  using   a fibre-stub type interface. Sub-surface  cracks  and fractures  are  not  considered  in this standard. In general, the methods described    in this standard  apply  to 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. It is not the intention of this standard that the  size of scratches should be measured, the dimensions and requirements are selected such that they can be estimated. There  is no need to measure for example if a scratch is 2,3 m wide. This second edition cancels and replaces the first edition published in 2009 and constitutes a technical revision. This edition includes the following significant  technical changes with respect to    the previous   edition:
- modification to the title;
- addition of some terms and definitions;
- reconsideration of the specific values of Tables 1 to 4 to reflect the current market situation;
- addition of visual requirements for single-mode transceivers using a fibre-stub interface in Table 3;
- addition of a sentence in 4.1 concerning the susceptibility of the methods to system variability.
