The fiber optic is a transmission channel with low attenuation and large bandwidth. These characteristics allow to achieve a great distance and a high data rate. The synchronizer main function is to sample and to retime the data bits. The objective is to study the synchronizer performance in the global system in the presence of noise.engDigital communicationFiber opticSynchronizerconference object
