What is BS EN 60793‑1‑48 - Polarization mode dispersion in optical fibres about?
BS EN 60793‑1‑48 is a part of the BS EN 60793 multi-series that discusses optical fibres.
BS EN 60793‑1‑48 applies to three methods of measuring polarization mode dispersion (PMD), which are described in Clause 4. BS EN 60793‑1‑48 establishes uniform requirements for measuring the PMD of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes.
Who is BS EN 60793‑1‑48 - Polarization mode dispersion in optical fibres for?
BS EN 60793‑1‑48 on polarization mode dispersion in 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 60793‑1‑48 - Polarization mode dispersion in optical fibres?
Polarization mode dispersion (PMD) causes an optical pulse to spread in the time domain. This dispersion could impair the performance of a telecommunications system. The effect can be related to differential phase and group velocities and corresponding arrival times δτ of different polarization components of the signal.
BS EN 60793‑1‑48 provides you with three methods to measure polarization mode dispersion in optical fibres and cables. BS EN 60793‑1‑48 also defines three approaches for each of the methods. These approaches provide you with the means to calculate and express PMD in multiple frequencies. The test results of the methods described in BS EN 60793‑1‑48 can help you to calculate other characteristics of optical fibres in the subsequent parts of the BS EN 60793 series.
In conclusion, the guidelines of BS EN 60793‑1‑48 help you to identify and measure PMD of single-mode optical fibre, thereby enabling you to take the necessary measures to improve the cable quality.
