A cassette which serves the purpose of connecting and branching light waveguides has a reserve length thereof for each of the waveguides deposited in the cassette in either a figure eight or circular or oval pattern. To accomplish this, the cassette is formed with upstanding holding devices which enable winding the waveguides in a figure eight pattern or in a circular pattern, or both. A plurality of the cassettes can be interconnected together to form a cassette block which can be opened hinge-like. To interconnect waveguides in one cassette with the other cassette, each of the cassettes is provided with an opening in a floor of the cassette and a portion of the side wall midway along the longitudinal side wall, which side wall is positioned adjacent a hinge interconnecting the cassettes together.
A cassette block comprising a plurality of cassettes for coupling and branching light waveguides, each cassette comprising a floor having a first longitudinal side wall, a second longitudinal side wall, and a pair of end walls upstanding from said floor, each cassette having deposit means for guiding light waveguides to enable them to be held in the shape of a figure eight configuration in the cassette and to enable them to be deposited in one half of the figure eight configuration, each cassette having first means for forming an opening adjacent each corner of the first and second longitudinal side walls for receiving incoming and outgoing leads, said first means supporting the lead adjacent the first longitudinal side wall to a extend obliquely to a center line of the cassette and outward of the deposit means and said first means supporting the lead adjacent the second longitudinal side wall to extend outwardly and longitudinally to the deposit means, each cassette having an opening mid-way along the first longitudinal side wall and a portion of the cassette floor adjacent thereto, and said cassette being joined together by a hinge positioned in the neighborhood of the first longitudinal side wall.
A cassette for the acceptance of light waveguides which are joined to one another by at least one element selected from a group consisting of a coupling element and a connector element, said cassette having a floor with a longitudinal first side wall, a longitudinal first side wall, a longitudinal second side walls, and a pair of end walls forming corners with the first and second side walls, said floor having deposit means for receiving and returning a wound waveguide, said deposit means being constructed to form a pair of ovals in line with each other to form a waveguide path with a shape of a figure eight to receive and retain the waveguide wound in a figure eight pattern and in a half of a figure eight pattern, said cassette having first means at each corner for forming an introduction opening for a lead having a light waveguide, a portion of the floor adjacent to a mid-point of the first side wall and a mid-region of the first side wall having second means for forming an access opening to enable passage of a waveguide through the floor, said first means at each corner of the first side wall supporting each lead to extend outwardly displaced with reference to the deposit means and obliquely to a center line of the cassette and the first means for the corners of the second side wall supporting the lead to extend longitudinally and outwardly relative to the deposit means.
