BS EN 60793-2-70:2017

What is BS EN 60793-2-70 – Polarization-maintaining fibres about ?

BS EN 60793-2-70 is a part of the BS EN 60793 multi-series that discusses optical fibres product specifications. 

BS EN 60793-2-70 is applicable to optical fibre types D1, D2, D3. These fibres are polarization-maintaining fibre types, and are used or can be incorporated in information transmission equipment and optical fibre cable. These fibres are available for use in optical transport networks. Three types of requirements apply to these fibres: 

• General requirements defined in BS EN 60793-2 
• Specific requirements common to the category D polarization-maintaining fibres covered in BS EN 60793-2-70 
• Particular requirements applicable to individual fibre types or specific applications 

Who is BS EN 60793-2-70 – Polarization-maintaining fibres for ?

BS EN 60793-2-70 on the sectional specification for polarization-maintaining fibres is useful for:

• Manufacturers of fibre optic cables
• Telecommunication companies
• Testing and inspection personnel

Why should you use BS EN 60793-2-70 – Polarization-maintaining fibres ?

Polarization-maintaining fibres (PMFs) are single-mode fibres that can carry randomly polarized light. PMFs can be created in the manufacturing phases by inducing stresses on the material itself. 

BS EN 60793-2-70 provides specific dimension, mechanical, and environmental requirements for D1, D2, D3 types of fibres and also provides you with reference to the standard documents that contain the test methods to verify these specifications.  

BS EN 60793-2-70 helps you minimize polarization crosstalk in optical fibres by facilitating in production of polarization-maintaining fibres.
