Abstract
Abstract A storage shelf (10) is provided for accommodating excess lengths of a plurality of optical cables (40) connected to and extending from electronic equipment. The storage shelf (10) includes a shelf housing (12) with an open front and two substantially vertical side walls (24, 26). The excess length of each optical cable (40) is coiled about the spool (42) formed in a cable storage cartridge (16). The storage cartridge (16) can be slidably inserted in the shelf housing (12) and stacked vertically therein. Each cable storage cartridge (12) has two opposable members (50, 52) closeable about a self hinge (56). The cable storage cartridge (16) further has two cable exit ports (44, 46) for allowing the two ends of the optical cable (40) to extend therethrough out of the cartridge (16) for connection with the telecommunications equipment.
