Resumen

Este artículo investiga el potencial de un sistema de particionado espectral óptico de doble polarización para permitir enlaces ópticos de alta capacidad en el segmento de la red de acceso a radio en la nube (C-RAN, Cloud-Radio Access Network) basados ​​en radio sobre fibra (RoF, Radio-over-Fiber) de una red 5G. Se describe analíticamente el proceso de generación de señal basado en particionado óptico con polarización dual y se realiza una demostración experimental para evaluar la viabilidad de la propuesta. Los resultados experimentales se centran en medir la magnitud del vector de error (EVM, Error Vector Magnitude) para ranuras ópticas de doble polarización de 0.1 nm, 0.5 nm y 1 nm. Los datos se miden experimentalmente para señales QPSK y 64QAM en frecuencias portadoras de 1.7 GHz y 3.5 GHz en 10 km de fibra óptica monomodo. Los resultados demuestran que una partición óptica de 0.1 nm con QPSK a 1.7 GHz conduce a un EVM de 2.4%, mientras que para 64QAM se observó un EVM del 4.5% bajo las mismas condiciones. Además, el modelo de simulación proyecta la viabilidad del transporte RoF de señales 64QAM a 1.7 GHz y 3.5 GHz en enlaces de fibra de 25 km y 16 km respectivamente.
