Nonlinearity in Fiber Optic Communication Technology
Nonlinearities of OPFs originated from the susceptibility of the third order (c3). As the length of the OPF increases, the interaction between the light and the fiber material also increases, resulting in enhanced. In recent years, significant research efforts have focused on mitigating its impact through two complementary approaches. The study examines many digital modulation methods, such as Differential Phase Shift Keying (DPSK), Return-to-Zero (RZ), and Non-Return-to-Zero (NRZ), and evaluates how they affect system performance and efficiency at high bit-rates.
