28、TIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC FILTERS GENERIC SPECIFICATION 1 Scope This International Standard 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 optoelectro

29、nic 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 can n

30、ot 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

31、: 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

32、 combination of the above categories. This standard establishes uniform requirements for optical, mechanical and environmental properties. 2 Normative references The following referenced documents are indispensable for the application of this document.
