Abstract

Un aparato de telecomunicaciones ejemplar (100) incluye una caja (103) un caja (103) que tiene una base de alojamiento (101) y una cubierta de caja (102) que se unen en una interfaz sellada. La cubierta de la cala (102) puede engancharse a la base de la caja (101). Un ensamble de bandeja de empalme (106) está dispuesta dentro del interior (104) de la caja (103). El ensamble de la bandeja de empalme (106) incluye bandejas de empalme (150() montadas en un inserto de administración. Un divisor (192) puede ser provisto en el inserto administrador. El inserto administrador también puede incluir una placa ranurada (160) asegurada a la placa base (180). Uno o más ensambles de puerto (107-109) permite que los cables entren y/o salgan de la caja (103) a través de puertos de cable sellados (145-147. Los ensambles de puerto (107-109) pueden proporcionar cables (214,234) para los miembros de refuerzo de cables y/u organizadores (243, 244, 253, 254) para esos tubos de fibra.
