Optical fibres - Part 1-60: Measurement methods and test procedures - Beat length

IEC 60793-1-60:2017 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. The phase beat length is the relevant parameter for the fibres ability to maintain a high extinction ratio. This is described in more details in Annexes A and B.
