This part of IEC 61300 provides methods for measuring the polarisation extinction ratio (PER) of single-mode, polarisation-maintaining (PM) optical components based upon PM fibres. This document also provides methods for detecting the input and output orientation of the PM components’ principal axes as well as methods for estimating the keying accuracy i.e. the angular misalignment between the principal axes and the mechanical reference key of the connectors, if these are present.

This document 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);

gain flattening (compensating the spectral profile of the device).

It is also possible to have a combination of the above categories.

This document provides the generic information including terminology of IEC 61753-04x series documents. Published IEC 61753-04x series documents are listed in the Bibliography.

This document establishes uniform requirements for the following:

optical, mechanical and environmental properties.
