What is BS EN 60793-2-30- A3 multimode fibresabout?
BS EN 60793-2-30 is a safety standard on A3 multimode fibres.
BS EN 60793-2-30 is applicable to sub-categories A3a, A3b, A3c, A3d, A3e, A3f and A3g. These fibres are used or can be incorporated in different information transmission equipment, other applications employing similar light transmitting techniques as well as fibre optic cables.
Three types of requirements apply to these fibres:
- General requirements, as defined in IEC 60793-2
- Specific requirements common to the category A3 multimode fibres covered in this standard and which are given in Clause 3
- Requirements applicable to the individual sub-categories or specific applications (e.g. automotive or industrial applications), which are defined in the normative subcategory annexes
Who is BS EN 60793-2-30- A3 multimode fibres for?
BS EN 60793-2-30 on the sectional specification for category A3 multimode fibres is relevant to:
- Manufacturers of A3 multimode fibres
- Suppliers of fibre optic products
- Manufacturers of fibre optic cables
- Testing authorities
Why should you use BS EN 60793-2-30- A3 multimode fibres?
The A3 multimode fibre consists of a glass core and a plastic cladding.
BS EN 60793-2-30 assists with the dimensional attributes and measurement methods of all categories of A3 fibres. BS EN 60793-2-30 also assists with relevant mechanical attributes and test methods, transmission attributes and measurement methods, and environmental attributes and test methods. The tests are normally conducted periodically as type-tests for a fibre design.
Overall, BS EN 60793-2-30 is useful as it provides guidance on the sectional specification for category A3 multimode fibres which can help you out in your business.
