All-optical 2r regenerator based on self-phase modulation
… based on self-phase modulation (SPM) in a single highly nonlinear fiber (HNLF) with 2500 km length of transmission is investigated. In addition, there are two types of modulation format namely, non-return�to-zero on-off keying (NRZ-OOK) and return-to-zero on-off keying (RZ-OOK) were investigated. …

Performance of four-stage cascaded fiber optical parametric amplifier (FOPA) using optisystem
An optical fiber plays a significant role to cater the increasing transmission capacity. In optical fiber, there is a few nonlinear effects. One of the nonlinear effects is four-wave mixing (FWM). In-depth analysis of FWM is conducted and it is found that one of the applications in the FWM is a …

Time-Frequency Localisation of Distributed Brillouin Optical Time Domain Reflectometry
… of the optic fibre. The performance of a highly nonlinear fibre that can generate a higher Brillouin scattering signal is compared to that of a standard single mode fibre. The results show that much higher SNR of the Brillouin scattering spectrum and smaller frequency uncertainties in the …
