Resumen:
IEC TR 61282-5:2019 which is a Technical Report, describes various
techniques for accommodation and compensation of chromatic
dispersion in fibre optic communication systems. These techniques
include dispersion compensation with passive optical components,
advanced dispersion management, and electronic accommodation of
dispersion in the transmitters and receivers. This second edition
cancels and replaces the first edition, published in 2002, and
constitutes a technical revision. This edition includes the
following significant technical changes with respect to the
previous edition:
a) extends the application space for dispersion compensation
and accommodation to communication systems that employ non-zero
dispersion-shifted fibres;
b) adds a discussion on the suitability of fibre types for
long-haul transmission of wavelength-multiplexed signals;
c) updates the dispersion coefficient limits for
dispersion-unshifted fibres;
d) adds information on the dispersion coefficients of
dispersion-shifted fibres;
e) updates the naming of the fibre types to the revised
naming conventions defined in IEC 60793-2-50:2018;
f) updates Table 2 to include the dispersion tolerance of
phase-shift-keyed modulation formats used for the transmission of
40 Gbit/s and 100 Gbit/s signals;
g) adds information on dispersion management in terrestrial
and submarine communication systems;
h) extends the description of passive dispersion
compensators based on fibre Bragg gratings and etalons;
i) adds information on electronic dispersion accommodation
in coherent communication systems (including transmitters and
receivers);
j) updates the description of optical accommodation
techniques to include soliton transmission and mid-span spectral
inversion;
k) extends the list of system parameters for passive
dispersion compensators to include wavelength-dependent loss, phase
ripple, and latency;
l) updates the description of dispersion compensator
applications in long-haul communication systems.
