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.
