Abstract
The present invention provides a precise optical fiber cable connector for aligning and connecting ends of a pair of cables. The connector has a fiber alignment block having a fiber receiving surface and a connector engagement surface. First and second openings are provided in the connector engagement surface. An alignment ball is provided and is retained in the first opening. The alignment ball is for aligning the connector with another like connector, and specifically, for aligning optical fibers carried on the connector alignment assemblies.
Claims11
A method of assembling an optical fiber cable assembly, the method comprising the steps of:
- providing an optical fiber cable having at least one optical fiber;
- providing at least one pair of connector alignment assemblies, the connector assemblies including connector engagement surfaces and alignment grooves;
- positioning the at least one pair of connector alignment assemblies in a face to face arrangement;
- positioning a spacing member between the connector engagement surfaces of the at least one pair of connector alignment assemblies;
- laying the optical fiber cable over the connector alignment assemblies such that individual fibers of the cable are positioned in each groove of the alignment grooves;
- and
- cutting the cable between the connector alignment assemblies.
A method of automating the assembly of at least a pair of optical connector alignment assemblies on a continuous optical fiber cable comprising the steps of repeating the method of claim 40 along a continuous length of optical fiber cable.
A method of attaching an optical fiber cable to a connector alignment assembly wherein the cable has a coating jacket thereabout and wherein the connector alignment assembly has a fiber alignment block having a fiber receiving surface for receiving optical fibers from the cable and a connector engagement surface, and a channel formed in the fiber receiving surface, at least one alignment groove formed in the channel, the method including the steps of:
- stripping the coating jacket off of a portion of the optical fiber cable;
- laying the optical fiber cable over the connector alignment assembly such that the stripped portion of the cable is positioned above the alignment grooves;
- and
- cutting any excess cable.
A method of abutting a pair of optical fiber cable ends in an aligned position using a pair of connector alignment assemblies wherein the cables are carried on the connector alignment assemblies having a fiber receiving surface for receiving optical fibers from the cables and a connector engagement surface, at least one alignment groove formed in the channel, first and second openings formed in the connector engagement surface, and an alignment ball retained in the first opening, the method including the steps of:
- positioning the connector engagement surfaces in a face to face arrangement;
- moving the connector alignment assemblies together so that the alignment ball of the first connector is inserted into the second opening of the second connector and the alignment ball of the second connector is inserted into the second opening of the first connector, thus aligning the fibers carried on the connector alignment assemblies.
