What is BS EN 60793-1-61 - Polarization crosstalk of PM fibres about?
BS EN 60793-1-61 is a part of the BS EN 60793 multi-series that discusses optical fibres.
BS EN 60793-1-61 establishes uniform requirements for measuring the polarization crosstalk of polarization-maintaining (PM) fibres.
BS EN 60793-1-61 gives two methods for measuring the polarization crosstalk of PM fibres. Method A is the power ratio method, which uses the maximum and minimum values of output power at a specified wavelength, and Method B is the in-line method, which uses an analysis of the Poincaré sphere.
Who is BS EN 60793-1-61 - Polarization crosstalk of PM fibres for?
BS EN 60793-1-61 on polarization crosstalk of PM fibres is useful for:
- Manufacturers of fibre optic cables
- Telecommunication companies
- Internet service providers
- Testing and inspection personnel
Why should you use BS EN 60793-1-61 - Polarization crosstalk of PM fibres?
Polarization crosstalk in PM fibres can arise due to multiple reasons. It can be due to fibre axis misalignment at fibre connections, PM fibre imperfections, or external mechanical stresses that cable might incur over its length. These factors can cause polarization crosstalk of varying amplitude and affect the performance of optical fibres.
BS EN 60793-1-61 helps you perform the two methods that can measure the polarization crosstalk in PM fibres and help you in enhancing the quality and performance of your optical fibres.
