Titel
640 Gbit/s DQPSK single-channel transmission over 480 km fibre link
Abstract
We report error-free transmission of a 640 Gbit/s DQPSK modulated signal over 6x80 km of dispersion-managed fibre. The DQPSK modulation together with polarization multiplexing enable the use of semiconductor-based components for the key devices.
