ABSTRACT:
A trough for safely retaining and routing fiber optic cables having a predetermined minimum bend radius entering or exiting an opening of a building entrance protector. The trough comprises of a cylindrical elongated O-shaped body defining a hollow space therebetween for retaining the cables, and a semi-circular curved gap on the body which provides cables access to the space. A pair of ribs extend from the body for slidable engagement with slots of the openings of a building entrance protector. The cross-section of the cylindrical body and the semi-circular curved gap have a predetermined radius equals to or greater than the minimum bend radius prescribed for the fiber optic cables. The trough has two separate retention mechanisms for securing it with the openings of a building entrance protector. The first retention mechanism is of a protrusion-recess type, located at the ribs and slots of the opening respectively. The second retention mechanism is of a latch-groove type, located at the bottom section of the body and along the opening of the building entrance protector respectively.
