This part of IEC 61282 is a guideline providing methods of
\nrepresenting the process statistics of the chromatic dispersion of
\noptical fibres and related components that may be combined in a
\nlink.<\/p>\n
Chromatic dispersion (ps\/nm) is the derivative, with respect to
\nwavelength, of the group delay (ps) induced by the spectral content
\nof light propagating through an optical element or fibre. Chromatic
\ndispersion is normally a function of wavelength and can be either
\npositive (group delay increasing with wavelength) or negative
\n(group delay decreasing with wavelength).<\/p>\n
The presence of chromatic dispersion can induce distortions in
\nsignals leading to bit errors depending on<\/p>\n
\u2013 source spectral width;<\/p>\n
\u2013 source chirp;<\/p>\n
\u2013 bit period;<\/p>\n
\u2013 distance.<\/p>\n
In addition, chromatic dispersion is interactive with the
\neffects of non-linear optical effects and second order polarisation
\nmode dispersion (PMD). The above system impairments are beyond the
\nscope of this technical report.<\/p>\n
When different components or fibres are combined, the chromatic
\ndispersion of the combination is the total of the chromatic
\ndispersion values of the individuals, on a wavelength-
\nby-wavelength basis. A section with high chromatic dispersion will
\nbe balanced by sections with lower values. The variation in the
\ntotal dispersion of links will therefore be dependent on the
\ndistributions of the products that are used in the link. This
\ndocument provides methods to calculate the distribution statistics
\nof concatenated links based on information on the distributions of
\ndifferent fibre or component populations.<\/p>\n
NOTE In the clauses that follow, examples are given for
\nparticular fibre and component types. These examples are not
\nnecessarily broadly representative.<\/p>\n","protected":false},"excerpt":{"rendered":"
