IEC 61977 Ed. 2.0 en:2010

IEC 61977:2010(E) applies to the family of fibre optic filters. These are passive components used to select specific wavelengths. The standard covers their optical, mechanical and envoronmental properties; as well as the measurement and text procedures for quality assessment. The changes with respect to the previous edition include having substantially increased the number of terms, added an informative annex for example of filtering technologies and deleted quality assessment procedures.
