43 Gb/s DQPSK transmission over fibre with 2450 ps/nm of dispersion using electronic pre-equalization

Electronic pre-equalization of chromatic dispersion for 43 Gb/s DQPSK has been demonstrated employing a developed test chip. The chip enables the BER in fibre with 2450 ps/nm of dispersion to be improved to 7.6E-05 without an optical dispersion compensator.
