What is BS EN 61300-3-32- PMD of passive fibre optic device about?
In the frequency domain, the polarization properties of the DUT are analysed. In the time domain approach, the pulse delay or broadening is observed.
BS EN 61300-3-32 presents several alternative methods for measuring the polarization mode dispersion (PMD) of a passive fibre optic device under test (DUT). These methods typically measure PMD using either a frequency domain or time-domain approach.
BS EN 61300-3-32 describes a procedure that is to be applied to laboratory, factory, and field measurements of PMD in passive fibre optic devices. This procedure is also applied to a transmissive or reflective DUT.
Who is BS EN 61300-3-32 - PMD of passive fibre optic device for?
BS EN 61300-3-32 on polarization mode dispersion measurement for passive optical components is relevant to:
- Manufacturers of fibre optic interconnecting devices and passive components
- Manufacturers of optical detectors
- Manufacturers of testing equipment and apparatus
- Fibre optic technicians
- Fibre optic installers
- Testing authorities of polarization mode dispersion
Why should you use BS EN 61300-3-32 - PMD of passive fibre optic device?
Polarization mode dispersion (PMD) refers to the spreading of an optical pulse due to polarization-related anomalies. PMD in passive fibre optic devices is usually deterministic by nature meaning that the phenomenon is predictable, can be reproduced, and controlled.
In optical passive fibre optic devices, the mode coupling is typically referred to as negligible or no or negligible (including the cases of polarization maintaining fibres and short lengths of ordinary fibre) as opposed to random or strong mode coupling such as frequently seen in the case of long lengths of fibre.
BS EN 61300-3-32 lays down the technicalities for measuring the polarization mode dispersion (PMD) of a passive fibre optic device under test (DUT). BS EN 61300-3-32 gives you detailed information about various techniques that are used to measure the PMD of a fibre optic device such as the stokes parameter evaluation method, polarization phase shift method, fixed analyser measurement method, interferometric method, and modulation phase-shift method.
BS EN 61300-3-32 gives a procedure that covers measurements of both broadband and narrowband dense wavelength division multiplexing (DWDM) passive fibre optic devices. Differences between measurement practices for these varied classes of passive fibre optic devices are noted in the text.
Overall, BS EN 61300-3-32 is useful as it provides guidance on the polarization mode dispersion measurement for passive optical components, which can be helpful for your business.
