Abstract

La presente invención se refiere a un sistema de distribución de potencia en redes de acceso de fibras ópticas utilizando cajas ópticas (10), comprendiendo un bus de cajas ópticas conteniendo por lo menos una caja óptica de derivación (10) conectada en secuencia y finalizado con una caja de terminación (12). Por lo menos una 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’), a la referida caja óptica de derivación (10) un divisor de entrada (DE) para dividir, de forma desbalanceada, la potencia óptica de entrada (A’) recibida en la caja óptica (10) del bus en dos partes. Una primera parte de la potencia óptica de entrada (A’) es conducida a 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 (A’) es conducida a una siguiente caja óptica (10, 12) del bus por un cable de continuación (CC), y así sucesivamente hasta alcanzar la referida última caja óptica de terminación (12), en la cual la potencia óptica de entrada es integralmente ofrecida a los cables ópticos terminales (CT) de usuario.The present invention relates to a power distribution system in fiber optic access networks using optical boxes (10), comprising an optical box bus containing at least one optical junction box (10) connected in sequence and terminated with a termination box (12). At least one optical junction box (10) receives a distribution or branch cable (CD) formed by a single optical fiber offering a certain optical input power (A '), to the referred optical branch box (10) an input splitter (DE) to divide, in an unbalanced way, the optical input power (A ') received in the optical box (10) of the bus into two parts. A first part of the optical input power (A ’) is driven to 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 user terminal optical cables (CT). A second part of the optical input power (A ') is conducted to a next optical box (10, 12) of the bus by a continuation cable (DC), and so on until reaching said last terminating optical box (12 ), in which the optical input power is integrally offered to the user's optical terminal (CT) cables.
