Abstract

La presente invención se refiere a un sistema de distribución de señales de comunicación y potencia en redes de acceso de fibras ópticas utilizando cajas ópticas, comprendiendo un bus de cajas ópticas conteniendo tres cajas ópticas de derivación (10) conectadas en secuencia y una caja de terminación (12). La primera caja óptica de derivación (10) recibe un cable de distribución o de derivación (CD) formado por una única fibra óptica ofreciendo una determinada potencia óptica de entrada, a la referida caja óptica de derivación (10) que posee un divisor de entrada (DE) para dividir, de forma desbalanceada, la potencia óptica de entrada recibida en la caja óptica (10) del bus en dos partes. Una primera parte de la potencia óptica de entrada es conducida para un divisor de salida (DS), el divisor de salida (DS) dividiendo la primera parte de la potencia óptica en potencias ópticas que son selectivamente transferidas a los respectivos cables ópticos terminales (CT) de usuario. Una segunda parte de la potencia óptica de entrada es conducida a la segunda caja óptica (10) del bus por un cable de continuación (CC) formado por una única fibra óptica, y así sucesivamente hasta alcanzar la referida caja de terminación (12), en la cual la potencia óptica de entrada está disponible totalmente a los cables ópticos terminales (CT) de usuario. La razón de la división de los divisores de entrada (DE) de cada una de las tres cajas ópticas de derivación (10) varía entre 70/30 y 90/10, siendo el numeral antes de la barra el porcentaje de la potencia encaminada para la próxima caja óptica (10,12) del sistema y el numeral después de la barra el porcentaje de la potencia encaminada al divisor de salida (DS) y a los cables de acceso (drop).The present invention relates to a communication and power signal distribution system in fiber optic access networks using optical boxes, comprising a bus of optical boxes containing three optical junction boxes (10) connected in sequence and a termination box (12). The first optical junction box (10) receives a distribution or branch cable (CD) formed by a single optical fiber offering a certain optical input power, to the referred optical junction box (10) that has an input splitter (DE) to divide, in an unbalanced way, the optical input power received in the optical box (10) of the bus into two parts. A first part of the optical input power is conducted for an output splitter (DS), the output splitter (DS) by dividing the first part of the optical power into optical powers that are selectively transferred to the respective terminal optical cables (CT) ) of user. A second part of the optical input power is conducted to the second optical box (10) of the bus by a continuation cable (CC) formed by a single optical fiber, and so on until reaching the said termination box (12), in which the optical input power is fully available to the user's optical terminal cables (CT). The ratio of the division of the input splitters (DE) of each of the three optical junction boxes (10) varies between 70/30 and 90/10, the numeral before the bar being the percentage of the power routed to the next optical box (10.12) of the system and the number after the bar the percentage of the power directed to the output splitter (DS) and the access cables (drop).
