Abstract: An optical cable fixture includes a base and a cover. The base defines a receiving groove penetrating opposite sides of the base. The receiving groove includes a first receiving portion and a second receiving portion. The first receiving portion receives an optical cable. The second receiving portion receives first optical fibers extending from the optical cable. The cover covers the base and fixes the optical cable and the first optical fibers.

Abstract: An optical fiber shuffle includes a protective shell and a number of crossover optical cables. The protective shell supports and fixes the crossover optical cables. Each of the crossover optical cables includes a support member, a number of first optical cable units, and a number of second optical cable units. The support member is coupled to the number of first optical cable units and the number of second optical cable units. Each of the first optical cable units includes a number of optical fiber units. The optical fiber units extend into the support member, are sequentially redistributed in the support member, and enter into corresponding second optical cable units. Ends of the first optical cable units facing away from the support member and ends of the second optical cable units facing away from the support member are coupled to a corresponding optical module.

Abstract: An optical fiber array device includes a substrate, a cover plate, and a ceramic ferrule array. A receiving groove is defined in one surface of the substrate. The substrate and the cover plate are coupled together and cover the receiving groove. The receiving groove includes a first groove wall and a second groove wall. The ceramic ferrule array includes at least one layer of ceramic ferrules and a number of positioning members. Opposite sides of the at least one layer of ceramic ferrules respectively abut the first groove wall and the second groove wall. Each of the positioning members is located between two adjacent ceramic ferrules.

Abstract: A fiber optic crossover cable includes a first cable portion, a second cable portion, a crossover distribution unit, and fiber optic subunits. The first cable portion includes an M number of first cable units. Each of the M number of first cable units includes an N number of the fiber optic subunits. The second cable portion includes an N number of second cable units. Each of the N number of second cable units includes an M number of the fiber optic subunits. The M number of first cable units and the N number of second cable units are arranged in the crossover distribution unit. The N number of fiber optic subunits respectively extend to the N number of second cable units. The M number of fiber optic subunits respectively extend to the M number of first cable units.

Abstract: A high-density fiber array unit includes a plurality of substrates arranged and connected in an array, a side plate arranged at one side of the plurality of substrates and connected to one of the plurality of substrates, and a plurality of fibers. Each substrate comprises a first surface and a second surface opposing the first surface, and the first surface defines positioning grooves. The side plate is connected to the first surface of one of the substrates, and each fiber can be fixed to and held by a positioning groove. A fiber array apparatus including the fiber array unit is also provided.
