BS EN 60793-1-60:2017

What is BS EN 60793-1-60 — Beat length of optical fibres about?  

BS EN 60793-1-60 is a part of the BS EN 60793 multi-series that discusses optical fibres. 

BS EN 60793-1-60 defines test methods for both the phase beat length, and the group beat length. These two parameters are defined differently, and will give different results depending on the type of polarization-maintaining (PM) fibre. 

Who is BS EN 60793-1-60 — Beat length of optical fibres for? 

BS EN 60793-1-60 on beat length of optical fibres is useful for: 

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

Why should you use BS EN 60793-1-60 — Beat length of optical fibres?  

Beat length is an important measurement aspect in optical fibres as it measures the polarization-preserving performance of an optical fibre. A fibre with a short beat length is more desirable as it preserves polarization more effectively than a fibre with a longer beat length. 

BS EN 60793-1-60 helps you perform the test methods to calculate the phase beat length and group beat length of optical by providing you apparatus requirements, step-by-step procedures for test methods and formulas to determine the optical fibres beat length. 

Overall, BS EN 60793-1-60 helps you to calculate the polarization-preserving performance of optical fibres, which in turn can help you to maintain the beat length of optical fibre to a minimum.
