ABSTRACT:
The present invention provides an optical fiber buffer loop management system which may be incorporated into a conventional interconnection box and which comprises one or more spools or pins around which optical fiber buffer loops are loosely dressed. Strategically placed cover guards forming narrow insertion slots for the fibers are attached to the tops of the spools or pins to prevent the fibers from unraveling. By loosely dressing the fiber loops in the interconnection box, no excess slack exists in the portion of the loop running from the spool to the point at which the plug connector on the end of the buffer loop is connected to the coupling located inside of the interconnection box. Preferably, each of the buffer loops is loosely wrapped about two spools in a figure-of-eight configuration, which allows a buffer loop density approximately four times greater than that of the prior art systems to be achieved without bending the fibers beyond their minimum bend radii. By loosely retaining the buffer loops in the interconnection box, as opposed to wrapping them tautly, the buffer loops can be easily unraveled when repairs are to be made. The present invention also provides a method for replacing faulty plug connectors. In order to replace a faulty plug connector, the plug connector is removed from the coupling device in the interconnection box and the optical fiber is cut so as to separate the plug connector from the optical fiber. The optical fiber is then removed from around the spool or spools and a new plug connector is then secured to the optical fiber. The new plug connector is then connected to the coupling device. The buffer loop is then wrapped about the spools in a figure-of-eight configuration as discussed above.
