Nowadays, the long-haul optical fiber communication system is one of the
important way to convey the information, and there is strong competition of research
in the optical long-haul transmission to achieve high channel bit rates and large
transmission capacity. Therefore, it is important to study a technology to improve the
performance of such system. The return-to-zero differential phase-shift keying
(RZ-DPSK) and the return-to-zero differential quadrature phase-shift keying
(RZ-DQPSK) have received renewed attention recently for the long-haul transmission
systems, because they can improve the transmission performance of the long-haul
system.
Furthermore, the design of the dispersion map becomes significantly different
from that of the conventional system using the intensity modulation direct detection
(IM-DD) scheme. Besides, the RZ-DQPSK can transmit two bits per symbol, so it has
twice the spectral efficiency of the RZ-DPSK. This study is focusing on the difference
of the transmission performance of the long-haul RZ-DQPSK system due to the
dispersion map using the numerical simulation.
