Optical transmission path for high data-rates, has all transmission path sections except last one, provided with over-compensation for first order dispersion

摘要

An optical transmission path has transmission sections (SP 1,2,3,4) and discrete dispersion compensation units (DCF), and with the transmission sections (SP1,2,3,4) except for the last section (SP4) for first order (D1) dispersion each have an over-compensation for the dispersion, and the transmission paths (SP1,2,3,4) at the end of the last transmission section (SP4) have approximately a complete compensation after dispersion compensation. The transmission sections (SP1,2,3) except the last one (SP4), do not have complete compensation for the second order and higher orders of dispersion and the transmission path at the end of the transmission section (SP4) has at least approximately complete compensation.
