Simulación de la transmisión de información a través de la fibra óptica con modulación 16-QAM

Abstract

The following article shows a proposal for a network based on optical fiber, implementing in the electrical domain the generation of the I, Q signals of the information to be sent through the fiber, which is modulated in 16-QAM with different transmission rates which are 20, 50 and 100 Gbps. It will be transformed into the optical domain with the help of MZM modulators. The quadrature modulation of the 16 QAM system will be implemented in the optical domain generating an offset to be combined and transported to the fiber by implementing PMF fiber-based X couplers. Finally, a quadrature demodulation system and DPS systems will be implemented for the correction of bit errors due to Chromatic Dispersion that is generated in the optical fiber, which its length change between 20, 50 and 100 Km emulating FTTH environments.
