Possible scenario for upgrading long-haul undersea optical fiber cable system using RZ-DPSK modulation format.
A numerical study focusing on the feasible upgrade scenario of long-haul undersea optical fiber cable system is discussed. At first, appropriateness of the simulated performance is confirmed through conventional IM-DD modulation format. Then, capacity upgrade of the system is attempted by adopting the RZ-DPSK modulation format. As the RZ-DPSK format alone does not make capacity upgrade possible, additional methods are considered, and the modification of the dispersion map is revealed to be effective. The results show that it is possible to double the capacity of the long-haul undersea system using the RZ-DPSK modulation combined with the dispersion map modification.
