What is BS EN IEC 61977 about?
BS EN IEC 61977 applies to the family of fibre optic filters. These components have the following general features:
They are passive because they contain no optoelectronic or other transducing elements that 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
