IEC 61753-087-2:2010 contains the minimum initial performance, test and measurement requirements and severities which a fibre optic pigtailed 1 310 nm upstream and 1 490 nm downstream wide wavelength division multiplexing (WWDM) passive optical network (PON) device must 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.

IEC 60875-1:2010 applies to non-wavelength-selective fibre optic branching devices which:
- are passive (they contain no optoelectronic or other transducing elements) and
- have three or more ports for the entry and/or exit of optical power which is shared among these ports in a predetermined fashion. This fifth edition cancels and replaces the fourth edition published in 2000. It constitutes a technical revision. The changes with respect to the previous edition are to delete the clause of Quality assessment procedures and reconsider the constitution of this standard.

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.
