<p>A means for encasing fiber optical cable is presented which provides security, ease of installation and strength. The casing (1) is made of two identical halves (5, 5') which are manufactured from standard angle iron. The two identical halves (5, 5') are joined together at the bottom by pinned hinges (6) and at the top by off-set corresponding bolt holes (7) and bolts (12, 12'). The pinned hinges (6) on the bottom of the two halves allow the halves to open up so that the casing (1) can be placed around the optical fiber cable. The two halves (5, 5') are then closed and clamped together to form a strong and permanent protection for the optical fiber cable, either by bolts (12, 12') or by the security lock (22). One end of the main casing (1) has a male projection (2) with a chamfered outer edge with bolt notches which is inserted into the female end of a second length of casing. The chamfered edge allows easy insertion of the male end into the female end. The female end of the casing has bolt holes (8, 8') at the top and bottom. When bolts (12, 12') are inserted through the bolt holes (8, 8') and the outer female end is tightened about the inner male projection, a firm and secure connection between the two lengths of casing is accomplished. Alternatively, a security lock (22) may be placed through the bolt holes (8, 8') to allow access to the cable only by authorized personnel.</p> |
