Omfang

IEC 61977:2015 applies to the family of fibre optic filters. These components have all of the following general features: - they are passive for the reason that they contain no optoelectronic or other transducing elements which can process the optical signal launched into the input port; - they modify the spectral intensity distribution in order to select some wavelengths and inhibit others; - they are fixed, i.e. the modification of the spectral intensity distribution is fixed and cannot be tuned; - they have input and output ports or a common port (having both functions of input and output) for the transmission of optical power; - the ports are optical fibre or optical fibre connectors; - they differ according to their characteristics. They can be divided into the following categories: - short-wave pass (only wavelengths lower than or equal to a specified value are passed); - long-wave pass (only wavelengths greater than or equal to a specified value are passed); - band-pass (only an optical window is allowed); - notch (only an optical window is inhibited). It is also possible to have a combination of the above categories. This standard establishes uniform requirements for the following: optical, mechanical and environmental properties. This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - harmonization of a number of terms and definitions with other generic specifications; - deletion of the quality assessment level clause. Keywords: fibre optic filters generic specification
