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 embarrado de cajas ópticas conteniendo por lo menos una caja óptica de derivación (10) conectadas en secuencia y terminado por 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, suministrando una determinada potencia óptica de entrada (A’), la referida caja óptica de derivación (10) poseyendo un divisor de entrada (DE) para dividir, de forma desbalanceada, la potencia óptica de entrada (A’) recibida en la caja óptica (10) del embarrado en dos partes. Una primera parte de la potencia óptica de entrada (A’) 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 (A’) es conducida a una siguiente caja óptica (10, 12) del embarrado por un cable de continuación (CC), y así sucesivamente hasta ser alcanzada la referida última caja óptica de terminación (12), en la cual la potencia óptica de entrada es integralmente suministrada a los cables ópticos terminales (CT) de usuario.The present invention refers to a power distribution system in fiber optic access networks using optical boxes (10), comprising a busbar of optical boxes containing at least one optical junction box (10) connected in sequence and terminated by a termination box (12). At least one optical branch box (10) receives a distribution or branch cable (CD) formed by a single optical fiber, supplying a certain input optical power (A '), the referred optical branch box (10) having an input divider (DE) to divide, in an unbalanced way, the input optical power (A ') received in the optical box (10) of the busbar into two parts. A first part of the input optical power (A ') is conducted for an output splitter (DS). The output splitter (DS) dividing the first part of the optical power into optical powers that are selectively transferred to the respective optical end user cables (CT). A second part of the input optical power (A ') is conducted to a next optical box (10, 12) of the busbar by a continuation cable (CC), and so on until the referred last optical termination box ( 12), in which the input optical power is integrally supplied to the user terminal optical cables (CT).
