The BS EN 61290 series is a European Standard series that discusses optical amplifiers. BS EN 61290 provides you with test methods and gain transient parameters for optical amplifiers.
BS EN 61290-11-1 applies to all commercially available optical amplifiers (OAs), including optical fibre amplifiers (OFAs) using active fibres, semiconductor optical amplifiers (SOAs), and planar wave guide optical amplifiers (PWOAs).
The test method described in BS EN 61290 requires a polarised signal at the input of the polarimeter with a degree of polarisation (DOP) of at least 25 %. Although the test source is highly polarised, the DOP at the output of the OA is reduced by amplified spontaneous emission (ASE). Annex A analyses the impact of ASE on the DOP. In order to assure an accurate measurement, the DOP is measured as part of the measurement procedure.
The method described in BS EN 61290 has been shown to be immune to polarisation-dependent gain (PDG) and polarisation dependent loss (PDL) up to approximately 1 dB.
BS EN 61290-11-1 on Optical amplifiers is useful for:
Polarisation mode dispersion (PMD) is a form of modal dispersion that causes random spreading of optical pulses.
This test method describes a procedure for measuring the PMD of optical amplifiers. The measurement result is obtained from the measurement of the normalised Stokes parameters at two closely spaced wavelengths on which Jones matrix eigen analysis (JME) is applied.
BS EN 61290-11-1 guides you with details such as apparatus, procedure, and calculations help you determine the efficiency of optical fibre amplifiers.
Using BS EN 61290-11-1 guidelines, you can determine the effectiveness of optical fibre amplifiers, which helps you with new product development so that customers have access to high-speed networks.
