Popis

BS EN 60027-3:2007


This standard BS EN 60027-3:2007 Letter symbols to be used in electrical technology is classified in these ICS categories:
  • 33.180.20 Fibre optic interconnecting devices
  • 01.060 Quantities and units
  • 29.020 Electrical engineering in general
  • 01.075 Character symbols
IEC 61753-381-2:2016 contains the minimum initial test and measurement requirements and severities which a Gaussian-passband-profile cyclic arrayed waveguide grating (AWG) for single-mode and bidirectional transmission systems satisfies in order to be categorised as meeting the requirements of IEC 61753-1 for category C (controlled environment). This standard pertains to wavelength division multiplexing (WDM) network with multiple spectral-band usage. This standard covers the requirements of cyclic AWG devices with free spectral range (FSR) characteristics to ensure multiple spectral bands transmission performance, with single-mode non-connectorised pigtails and no electric circuit board. Keywords: Gaussian-passband-profile cyclic arrayed waveguide grating (AWG), wavelength division multiplexing (WDM), category C (controlled environment)
