Status: active
Page Count: 38
ICS Code (Fibre optic interconnecting devices): 33.180.20
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 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.
